By Delphine Kimpel, BASF SE; and Jonathan Wattras and Mervin Wood, BASF Corporation The light stabilization of coatings has been a challenge for many years in the paint industry. Over four decades ago, it was discovered that hindered amine light stabilizers (HALS) play a significant role in the light stabilization of polymers and resin binders. Typically, these compounds are … [Read more...] about Light Stabilization of UV-Curable Formulations with Focus on Extreme Lightfastness

By Jennifer Heathcote, vice president, Business Development, GEW (EC) Limited UV curing is an environmentally friendly processing tool that allows manufacturers to instantly set inks, coatings and adhesives that have been applied to a web, sheet or part without the aid of solvent or water-based carriers. Since the carrier is eliminated, there is no need for evaporation using … [Read more...] about Clarifications on 2027 Expiration of RoHS UV Mercury Vapor Lamp Exemption

By Stacy Hoge, marketing manager, Excelitas UV and UV LED curing technologies are foundational to modern electronics manufacturing, enabling fast, precise and low-temperature bonding, sealing, coating and protection of sensitive components. Their rapid cure times, minimal thermal load and high repeatability make them essential for high-density, thermally constrained … [Read more...] about Architectural Considerations for Modern UV Curing in Electronics Manufacturing
