By Mike J. Idacavage, PhD, Technical Marketing Adviser, and John Arnold, PhD, Director of Research and Development, Miltec UV Introduction Many commercial sheet-fed litho printing presses that are used to print on flat steel sheets for the can industry, or on paper or plastic sheets, utilize traditional UV arc lamps that are cooled by a combination of water and air to help … [Read more...] about UV Source and Chemistry Options for Metal Can Coating

Viscosity Control of Spray Applied Coatings – Balancing Environmental Compliance and Performance
By Kristy Wagner, Red Spot Paint and Varnish Abstract Solvent-free, UV-curable coatings can be the first choice for many finishers looking to simplify their regulation processes. However, other options may be available for UV-curable, spray-applied coatings that can maximize process windows and still keep costs and regulatory issues manageable. Introduction To avoid … [Read more...] about Viscosity Control of Spray Applied Coatings – Balancing Environmental Compliance and Performance
Adhesion Enhancement of UV-Cure Inks onto Polymers by Gas-Phase Plasma Pretreatments
By Scott R. Sabreen, The Sabreen Group, Inc. Abstract The demand for UV-cure inkjet printing and coating onto two-dimensional and three-dimensional plastic products – including thin films – is rapidly increasing due to the advantages offered by full-color digital technology. Arguably, the most significant challenge to achieving robust print quality is inadequate adhesion to … [Read more...] about Adhesion Enhancement of UV-Cure Inks onto Polymers by Gas-Phase Plasma Pretreatments
POSS Coating Additives: Epoxy and Acrylic Tool Kits
By Joseph D. Lichtenhan, Hybrid Plastics Inc. Abstract Polyhedral oligomeric silsesquioxane (POSS®) additives provide a simple-to-use chemical tool kit that requires only small loading levels to improve traditional formulations. At 1.5 to 3.0 nm in diameter, POSS cages provide a tremendous amount of surface area and volume control when incorporated into formulations. These … [Read more...] about POSS Coating Additives: Epoxy and Acrylic Tool Kits
Researchers develop photoinitiators based on colloidal quantum materials
A team led by Uri Banin, Institute of Chemistry chair at Hebrew University of Jerusalem, has been working to develop photoinitiators based on colloidal quantum materials. The research, which was among those selected as tech accelerator winners for RadLaunch 2018, fills a previously unmet need for efficient, water-soluble photoinitiators for coatings, 2D or 3D printing and the … [Read more...] about Researchers develop photoinitiators based on colloidal quantum materials
