By Darrin Leonhardt, chief innovation officer and head of engineering, EIT 2.0 A UV curing line runs flawlessly for two years. Then the lamp supplier changes. The replacement units are the same wattage, the same lamp type, the same rated output. The radiometer reads within 2% of the original baseline. Three days into production, cure failures begin appearing downstream – … [Read more...] about UV-C Is Much More Than 10 Nanometers: Why the UV-C Band Demands Measurement

By Paolo Betti, synthesis manager, IGM Resins Self-curing resins represent a significant advancement in the field of polymeric materials in UV technology. Due to the increasing regulatory concerns linked to certain classes of low-molecular-weight photoinitiators, the development of formulations based on resins with built-in initiation capability has become an attractive … [Read more...] about Novel Self-Curing Resin with Glyoxylate Technology: A Formulation Tool for LED-Curable Coatings and Inks

By Liz Stevens, writer, UV+EB Technology The performance of modern optical devices – from extended reality headsets to organic light-emitting diode (OLED) displays and precision sensors – depends on the ability to precisely control how light behaves as it moves through layered materials. Refractive index, the measure of how much a material bends light, is a foundational … [Read more...] about Tunable Nanocrystals for Next-Generation Displays

By RadTech and UV+EB Technology staff The BIG IDEAS for UV+EB Technology Conference was held aboard the historic USS Midway Aircraft Carrier & Museum in San Diego, California, on March 2-3, 2026, offering RadTech members thought-provoking discussions and engaging, behind-the-scenes, eye-opening tours. This evening conference brought together leaders in photopolymer … [Read more...] about BIG IDEAS Shared in San Diego

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
