Photopolymerizable Hydrogel Polymers Modified With Magnetic Nanoparticles Coated With Cytostatics For Cancer Treatment

Anna Drabczyk, Cracow University of Technology

In presented research photopolymerizable hydrogels containing magnetic nanoparticles coated with cytostatic have been developed. Application of UV radiation allowed to obtain hydrogels in short time and without generation of any waste. Such materials may find application in the treatment of skin tumors, where they provide an adequate healing environment for external skin lesions, nanoparticles with cytostatic will penetrate the wound and the external magnetic field will prevent them from spreading throughout the body, limiting side effects.

Novel Approaches to Improve Scratch Resistance in UV Coatings

Bob Lin, Evonik Corporation

UV Coatings have evolved to protect a broad range of substrates. One of the main performance characteristics required is excellent scratch resistance. This ongoing search for improvement in scratch resistance has resulted in the development of a wide variety of additive technologies to address this functionality in the marketplace. Additives chemistries differ in their physical-chem properties and in their approach to improve scratch resistance performance. In this study, the paper addresses a range of available additive technologies which span from surface active siloxanes and nanocomposite technology to synthetic silica and co-binders; and evaluates them side-by-side in an urethane UV curable system. The study will look at compatibility of these products in a coating formulation as well as its impact on the scratch resistance measured by several common test methods. The results will provide a comparable overview of how these various technologies perform in improving scratch resistance of the UV coating.

Advancements and Challenges in "Easy-to-Clean" Coatings

Kristy Wagner, Red Spot Paint and Varnish

Electronic touch screens are no longer just a part of communication devices. They are now key components in automotive interiors and home appliances. As such, the demand for anti-fingerprint technology has increased dramatically. When you also consider the ramped-up development in autonomous vehicles, the need for dirt repellent hard coats is no longer an aesthetic want, but a critical safety need. The challenge to develop and evaluate “Easy-to-Clean” hard coats is a pressing issue in multiple coating markets. This paper will discuss some coating technologies, the challenge of quantifying the technology, as well as unmet needs in these areas.

High-Performance UV Curable Resin for Automotive Coatings

Marcus Hutchins, allnex

Light weighting, reduced carbon footprint, throughput, and sustainability are just some of the more common buzzards original equipment manufacturers (OEM) are using. They are looking for this advantage in not only the assembly process but every part and coating aspect that goes into that assembly. Going hand and hand with the challenges to improve the assembly process is the need to meet more stringent performance requirements. Allnex has developed a number innovative UV curable products that can be used in automotive refinish, films, conformal coatings, and glazing applications that maximize throughput and coating performance. This paper will discuss a variety of UV curable resins that can be used in a variety of automotive applications such as film and sheets used in IMD/IML, metallization, conformal coatings, structural adhesives and automotive refinish applications allowing formulators and finishers to capitalize on the intrinsic values of UV curable chemistry such as rapid throughput and excellent chemical and abrasion resistance.

Curing Functional Properties into UV Coatings: Direct Contactless Microfabrication of Anti-bacterial, Anti-fouling and Drag Reducing Microstructures

Henry C. Bilinsky, MicroTau Pty Ltd

Properties of a final cured surface are traditionally achieved through chemical means in formulating the UV curable coating. Different functional properties may also be produced through physical means resulting from microscopic patterns on a surface like as those found on the skin of plants and animals in nature. MicroTaus Direct Contactless Microfabrication (DCM) technology.

Achieving Ultra-Low Gloss Coatings Through the Use of Excimer Technology

Jonathan Shaw, allnex

There is a continuing desire for the aesthetic of ultra-low gloss in coatings in nearly every market and across many different substrates. There has also been a renewed interest in excimer technology as the desire for lower and lower gloss levels increases. This presentation will examine the technique of using excimer lamps to achieve ultra-low gloss levels and discuss the structure features desirable in an oligomer to take advantage of the technology.

Matting Optimization: Achieving High Quality, Ultra-Low Matte Radiation Curable Wood Coatings

Mike Toth, BYK USA

This presentation will explore the influencing factors and mechanisms required to optimize and successfully achieve desired matting for ultra-low gloss radiation-curable wood coatings. The application of wetting and dispersing additives to achieve these challenging demands is paramount. Tailor-made products are essential to meet all technical requirements, as well as to offer solvent-free delivery forms in which do not contribute volatile solvents to the coating formulation for solventborne, waterborne or solvent-free UV coating systems. Consideration for the use and benefits of wax alternatives to silica to improve surface features, as well as proper selection and balancing of the entire coating system to meet low matte requirements is of significant importance.

Curing Matte Finishes into UV Curable Wood Coatings by Direct Contactless Microfabrication

David Ivarsson, EFSEN UV & EB TECHNOLOGY

Matt finish for wood coatings are traditionally achieved by the use of matting agents that impose constraints on the application and resistance properties of the coating. This paper reports on a new process to cure matt finishes into UV curable wood coatings without the need for matting agents, by curing a micro-rough structure into the coating. This is a new application of the MicroTau Direct Contactless Microfabrication (DCM) technology originally developed for printing drag-reducing microstructures for aerospace applications. MicroTau and EFSEN UV & EB TECHNOLOGY are working together to integrate this technology into existing furniture manufacturing lines that utilize UV curing.

Aerospace UV Cured Coatings; Yesterday, Today & Tomorrow

Michael J. Dvorchak, Dvorchak Enterprises LLC

Over the last three decades suppliers to the Aerospace coatings industry, paint companies, the USAF, US Army, US Navy, US Coast Guard and civil aviation entities have, with limited success tried to implement the use of UV cure coatings. The benefits of the UV cure technology are well understood in that it will provide for the end user the following; immediate dry to fly, ultra-low VOCs and VHAPS, one component and technology that could potentially meet military specification MIL-PRF-85285D. From the early uses of UV-A cure stencils for Aerospace UV coatings the technology has evolved to the UV Cure Shark Skin coatings that have the promise of delivering drag reduction values in the range of 6-7%. Both the MicroTau Direct Contactless Microfabrication (DCM) technology and the Lufthansa Technik Airbus UV Cure Shark Skin coatings have the promise of accelerating these developments of Aerospace UV cure coatings acceptance in the market place. These UV cure technologies can be based on 100% oligomer as well as water based polyurethane dispersion technology. During this nearly three decades of development several hurdles have impeded UV Cure technology progress and use in the Aerospace market. This paper will report on these hurdles and potential solutions to further develop the UV Cure Aerospace coatings market.

Organic-inorganic hybrid coatings for high-performance protective coating applications.

Vijay Mannari, Eastern Michigan University

Sol-gel derived organic-inorganic hybrid (OIH) thin films and coatings have emerged as advanced materials for myriads of applications. Such films are typically applied from water or solvent-based composition and are generally limited to thin films < 2-5µm. We have developed novel materials and process that allows deposition of highly adherent and dense OIH films up to 30 µm, by leveraging photo-latent super acid and super base initiated UV-curing process. Besides many technical and environmental benefits, such coatings can find high-performance applications including superior corrosion resistance of metal substrates.

Silicon-based hydrogel with controllable swellability

Xiaoqun Zhu, Beijing University of Chemcial Technology

Hydrogels are three-dimensional polymer network containing lots of water inside. Hydrogels with the performance of water swelling resistance or controllable swelling are pursued by researchers. Such hydrogels have potential biomedical applications, such as tissue engineering. This research reports a simple way to prepare nonswellable, even controllable swellbility hydrogels from hydroxyethyl acrylate (HEA), hydroxypropyl acrylate (HPA) and methyl trimethoxy silane (MTMS) through photopolymerization and sol-gel process. The principle of this method to fabricate the controllable swellbility hydrogels is that HPA and MTMS change from good hydrophilicity to hydrophobicity before and after polymerization at room temperature, while both HEA and its polymer have good hydrophilicity. Controlling the ratio of HEA, HPA, MTMS and water, the hydrogels with different swellbility from nonswellable to different swelling degree could be fabricated.

Paper Upgrade - A Path to Realistic Looking Substrates

Jonathan Shaw, allnex

Substrates like LVT have demonstrated that realism is possible without using natural substrates. Digitally printed paper and foil can have the same effect when used to upgrade inexpensive substrates. We will look at what is needed to prepare the paper to receive high quality prints as well as what can be done to highlight the final look through the used of matte and gloss coatings, as well as provide long term protection if used in an exterior application.

POSS Oxirane and Oxetane Additives for Energy Cure Coatings and Adhesives

Joseph Lichtenhan, Hybrid Plastics Inc

POSS chemicals range in diameter from 1.5-3.0 nm and differ from traditional chemical additives by providing an envelope of effects. The effects are based on the rigidity, surface area, and volume provided by the cage in addition to traditional composition and chemical reactivity of the organic groups attached to each of the silicon vertices. POSS oxirane cure chemistry and resulting physical properties will be discussed and compared to acrylate chemistry and performance.

The Use of Anthracene Derivatives in UV-LED Curing

Mike J Idacavage, Advisor - Nagase America 

There is a strong interest in UV-LED curing of coatings, inks, adhesives, etc., due to the benefits of using UV-LED as the energy source. To meet the end user’s needs, resin formulators are drawing upon the list of available materials. While the range of monomers and oligomers that can be used is quite large, formulators are somewhat limited by the photoinitiators available. The UV-LED lamps that are most commonly used limit the available useful options with TPO being one of the most popular photoinitiators. The use of anthracene derivatives adds a good option for formulators looking to increase the cure speed even for thick coatings or lower the amount of initiator that is used in free radical based systems. When used in UV-LED cationic cured formulations, faster cure speed and less yellowing have been found due to the lack of sulfur, nitrogen or phosphorus in the additive structure. Anthracene derivatives also play a useful role in UV curable hybrid systems by improving cure speed.

Reactive diluents to overcome challenges in UV curable inkjet inks and coatings applications

Nikolas Kaprinidis, BASF

Solving the challenges facing UV-EB curable applications such as regulatory pressure for favorable toxicological profiles, enhanced performance characteristics and improved physical properties are addressed herein by oxazolidinone based reactive diluent structures. Vinyl methyl oxazolidinone offers significant technical benefits and formulating capabilities compared to traditional reactive diluents in the industry, such as NVP, NVC and ACMO. Advantages include very high reactivity with acrylates, good adhesion to various substrates, liquid form at room temperature, very low viscosity, low color and odor and a favorable toxicological profile.

UV+EB Technology With 1.5-Nanometer Heteroatom Titanates & Zirconates

Salvatore J. Monte, Kenrich Petrochemicals, Inc.

1.5-nanometer heteroatom titanates/zirconates form functional atomic monolayers on the interface of non-silane reactive inorganics and organics such as CaCO3, CNTs, BaSO4, BN, azodicarbonamide, etc. via proton coordination – absent the need for hydrolysis of surface hydroxyls as with silanes resulting in: complete deagglomeration; hydrophobicity; organophilicity; greater electron/thermal transfer efficiency; and age-resistant compositions. Ti/Zr catalysis mechanisms at 0.3 wt. % dosage increase polymer flow and flexibility with greater adhesion to a variety substrates.

Multi-functional dispersants for UV inks

Elliot Coulbeck, Lubrizol Ltd

Increased environmental awareness is driving the growth of the UV market. Pigments used historically in the Printing and UV markets often have challenges with respect to long term stability. As such, we have been focusing our research efforts into understanding the structure performance relationship of pigment surface and dispersion for printing applications (for example PY13 and PR57:1). This has allowed us to create novel multifunctional dispersants to give improved pigment dispersions. Their lower mill base viscosity facilitates higher millbase pigmentation levels.

Recyclable Packaging Options with Electron Beam Curing Technology

Imtiaz Rangwalla, Energy Sciences Inc.

Reduce Reuse and Recycle are the words are being used by major end users. Most of them have mandates to comply with re-cylability of packaging materials used for their products. Electron beam curing is providing an excellent option to use similar materials for packaging that are functional and allows for recylability. What are these materials and how electron beam curing is used will be discussed in detail. Also a recylable study done in cooperation with a major resin supplier will be presented.

Attainable Sustainable: Using Electron Beam Technology in Compostable Flexible Packaging

Karl Swanson and Sage Schissel, PCT Ebeam and Integration, LLC

Sustainable practices, including material reduction and the use of bio-based, recyclable, or compostable materials, are forefront in the minds of both consumers and the packaging industry. This is especially true for flexible packaging, which has traditionally consisted of multi-layer, non-recyclable structures. In this study, the use of ebeam technology in the life cycle of a compostable, flexible package was investigated.

Cyclopolymerizable UV Monomers introducing Tetrahydrofuran Rings into the Polymer Backbone.

Atsushi Tachibana, NIPPON SHOKUBAI CO., LTD.

2-(Allyloxymethyl)acrylates are known to generate unique polymers with tetrahydrofuran rings in the main chain. It was found those monomers are suitable for UV resins because of high reactivity and excellent property of cured materials . We recently established a commercial manufacturing process for methyl 2-(allyloxymethyl)acrylate and launched it as a UV curable monomer. Taking this opportunity, we will introduce the characteristics and usage examples of methyl 2- (allyloxymethyl) acrylate and its derivative monomers.

Mercapto functional silicone-based Q resins and other SH silicone resins are shown to be cross linked with vinyl silicone using UV light and photoinitiators. The materials are evaluated for physical properties and also a series of formulations are 3D printed looking for soft but printable resins.

Photopolymerization of Methylene Malonates

J. Taylor Goodrich, Sirrus Inc.

Methylene malonates can be UV cured similarly to (meth)acrylates. Since the double bond in methylene malonates is activated by two geminal electron withdrawing groups they are also readily polymerizable anionically by relatively weak bases. This work will explore initiation of methylene malonate systems with a photolatent base to overcome oxygen inhibition, as well as the creation of unique dual cure systems.

Properties of photo-cured networks using polyglycerin acrylates

Kimihiro Matsukawa, Kyoto Institute of Technology

Novel functional polyglycerin with acryl esters are used for photo-radical polymerization with usual multi-functional acrylate, for example, DPHA, which is well-known as a hard coating material, but there are some following disadvantages such as curlings, cracks, and non-flexible. In addition of polyglycerin acrylates to DPHA, it was found that these disadvantages can be overcome. These coatings on PET film are so flexible, that is a good candidate of effective monomer for the flexible hard coating. And also these show the property of anti-fogging.

In Situ 3D Printed Voxel Correction Using Hybrid AFM 3D Printer

Callie Higgins, NIST

Stereolithographic 3D printed parts are heterogeneous due to the resin absorptivity, diffusivity, reaction kinetics, and swelling during photoexposure. Using a novel hybrid atomic force microscope 3D printer, we are the first to characterize the heterogeneity induced by these affects across a single, in situ printed voxel. We also present and verify a method to correct these heterogeneities voxel by voxel using a grayscale mapping algorithm.

Comparison of UV- and EB-initiated Polymerizations Based on Equivalent Radical Concentration

Erin Peters, PCT Ebeam and Integration, LLC

In this study, a protocol was developed to investigate UV- and EB-polymerized films of equivalent radical concentrations. This protocol was then applied to an acrylate/methacrylate pair to characterize the impact of the initiation mechanism. Raman spectroscopy was used to determine differences in polymer conversion. Monomer chemistry was shown to be a key variable in the comparison of the two initiation mechanisms.

Real-Time Monitoring and Degree of Cure of UV-Cured Resin

Huan Lee, Lambient Technologies

High speed dielectric cure monitoring equipment enables studies of UV cured materials in ways not possible with most laboratory methods. This paper will present real-time measurements of changing cure state for several UV cured resins during and after exposure to UV light. The the utility of this technique allows the study of degree of cure and response to energy and duration of exposure.

Physical Properties of UV Curable Composites

Jonathan Shaw, allnex

There are a number of advantages to using UV vs. thermal energy to cure composites: increased throughput, very long pot lives, reduced waste, and a wide breadth of properties. A challenge for UV energy is depth of cure. Energy is attenuated with increasing composite thickness. We will present data on physical properties and double bond conversion vs. depth while varying photoinitiator type and concentration, and compare cure using mercury and LED lamps. We will also present information on dual cure systems, where the heat of polymerization can be used to drive a second cure reaction.

Curing with Multi-Wavelength LEDs

Brett Skinner, Heraeus Noblelight America

As UVLEDs improve in wall-plug efficiency at shorter wavelengths they will continue to displace mercury lamps in additional applications. This technology shift has been slow because formulators are unable to test which raw materials work for multi-wavelength exposures until the UV lamps are commercially available, causing a delay. This paper examines the effect of combined UVC/UVB/UVA exposures using supercooled LED lamps and bandpass filters under overdriven mercury lamps to mimic future technology in order to determine which raw materials are most effective and to accelerate UVLED adoption.

High-Powered UV LED Curing Systems

Jennifer Heathcote, GEW (EC) Limited

When it comes to UV LED curing, the industry mistakenly limits the discussion to wavelength and irradiance and incorrectly correlates high-powered with high irradiance. In reality, high-powered systems are those that exceed a minimum threshold irradiance at the cure surface followed by a large energy density to cure at faster line speeds. This paper discusses high-powered UV LED technology and what is needed for broader market adoption in faster speed and greater working distance applications.

Continuous current and pulse width modulation (PWM) UV LED systems: technical characteristics, advantages and applications

Rui Zhou, Phoseon Technology

Continuous wave and pulse width modulation (PWM) are two methods for controlling the current in an UV LED light source. Continuous wave radiation system typically provides better curing results primarily due to its stable UV output, especially in applications that requires high speed. On the other hand, the PWM system can help reduce the substrate temperature, which is beneficial to the process on heat sensitive materials. This article discusses the differences between the two technologies, the advantages of each, and their respective applications.

Optic concepts for UV LED lamps at long working distances

Thorsten Vehoff, Heraeus Noblelight GmbH

The small size of LEDs along with its excellent cooling possibilities allow the use of primary optics directly on top or in very close vicinity to the LED chips. These can shape the emitted light from an almost Lambertian (180°) emission to a 30-40° angle. This light can in turn be focused at a large distance by a set of secondary optics aligned and designed to match the corresponding primary optics as well as the LED substrate.

This allows light intensities of 8-10 W/cm2 at a distance of 8 cm, which is characteristic in the printing industry and could otherwise only be achieved at distances below 3 cm from the emission window of the lamp.

Photo-Activated Hydrosilation: Prospects for UV Curable Silicone Coatings Applications

Richard Eckberg, Momentive Performance Materials

Photo-activated platinum hydrosilation catalysts have been shown to initiate additive crosslinking of vinyl- and hydrido- functional silicone polymers upon irradiation from combinations of curing lamps tuned to catalyst absorption spectra. Novel UV curable silicone release coatings and elastomeric protective materials based on common inexpensive silicone inputs plus novel anhydride-siloxane additives can be quickly and efficiently processed and applied to a variety of paper and film substrates.

Multifunctional isocyanate monomer for UV curable applications

Siyi Qu, Showa Denko

Multifunctional isocyanate monomers, which contain isocyanate and double bond moieties, have been designed for performance enhancement of radiation curing formulations. It is found that the isocyanate groups in this series of monomers possess high reactivity compared to conventional isocyanates, thus they can be used to moderate reaction conditions or reduce the catalyst amount. The result shows that its unique structure also contributes to high UV sensitivity. Here, we report these properties and application data for the UV curing system.

Photo-active Polymeric Dormant: Controlled UV-curing and Nanostructure Evolution

Takeo Suga, Waseda University

Recent advances in photo-induced controlled radical polymerization provides further temporal (on/off) control of polymerization by light. Here we focus on organo-catalyzed iodine-transfer controlled radical polymerization, and synthesized polymeric dormant with C-I end group, which were utilized to the UV-curing process to challenge the precise control of photo-polymerization and phase-segregation simultaneously. The obtained coatings were optically clear, but internal nanostructure of the coating exhibited unprecedented, bicontinuous nanodomains with gradient size distribution. The process can be integrated to commonly used UV curing process, which gives a high impact to the functional coating applications.

Multifunctional secondary thiols for UV curing applications

Yotaro Hattori, Showa Denko

Thiol–ene reaction has been an efficient tool for photopolymerization and material functionalization. However, the drawback of using primary thiols with poor stability and strong orders has hindered its applications. Here, a multifunctional secondary thiol is produced and introduced in radical curable resins. It has shown high stability due to steric hindrance of the secondary structure. It also presents high quality and has a low odor due to unique manufacturing methods. This talk will discuss the characterization results of the multifunctional secondary thiols and their applications in UV curing and thiol-ene reactions.

Benefits of Formulating with Self-Curing Acrylic Resin In a World Filled with Photoinitiator Challenges

Amy Gran, Ashland LLC

Photoinitiators are integral to most UV cured coatings and adhesives, but supply shortages, increasing prices, and regulatory constraints have challenged formulators to provide products meeting all their customer’s needs. These industry struggles have created the opportunity to evaluate self-curing resin benefits not only for the formulator, but the end user. This paper describes the formulation of self-curing acrylic resin into a protective hard coat, improving the final product performance while reducing photoinitiator more than 80%.

James Goodrich, Miwon North America

With their distinct advantages, UV LED energy sources continue to move into new applications. And even with UV LED improvements, there is a distinct need for new and innovative acrylate chemistries to enhance cure while not being detrimental to the overall formulation performance. In this presentation we will cover the effect of changing various backbone structures of an acrylated amine and the positive, and negative, effects of those changes.

Preparation and characteristic of self-floating silica

Jun Nie, Beijing University of Chemcial Technology

This study has been focused at the research of self-floating hydrophobic silica particles by the Sol-gel process, which is a facile and an economical way. This method is created on occurrence of hydrolysis and condensation reactions, wherein Tetraethyl ortho-silicate (TEOS) and a synthetic product (octadecyl 2-((3-(triethoxysilyl) propyl) amino) acetate) SP are used as initiating precursor at different the ratios of TEOS: SP to form the silica particles. Silica particles in both liquid as well as powder forms at unalike configurations of weight percent have been exposed to the photo-polymerization (by UV-365 at light intensity of 22m W/cm2 for 60s) with polyethylene glycol diacrylate in the occurrence of (2- hydroxyl – 2 – methyl – 1- phenyl -1 – propanone (1173)) photo-initiator on a glass substrate. The aim of that report is to deliver a complete scientific advancement of hydrophobic self-floating silica to estimate its future perspective. The report concludes with a momentary conversation on the influence of silica and combines effect with linked materials on the environment and engineering prospectus and its upcoming scenes in this rapidly developing field.
