By Dr. Cristobal Garcia, senior scientist, Evonik Corporation You are having a picnic in the park on a summer morning and notice that the grass has small droplets of water attached to the surface. Later, you walk around the pond and observe insects standing on the water and quickly gliding through it, you see a kid blowing soap bubbles, and you spot a runner stopping to use … [Read more...] about Wetting Solutions for UV-Curable Inks

Improving Direct-to-Metal Adhesion of UV-Curable Coatings
By Carlo Trentalange, application chemist, Radlab AG Direct adhesion of acrylate-based UV coatings to metal surfaces traditionally has posed challenges due to the intrinsic kinetics of radical photopolymerization chemistry. Nonetheless, interest in UV technology for metal applications has grown significantly in recent years, primarily driven by the benefits of lower energy … [Read more...] about Improving Direct-to-Metal Adhesion of UV-Curable Coatings
Tunable Nanocrystals for Next-Generation Displays
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
Light Stabilization of UV-Curable Formulations with Focus on Extreme Lightfastness
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
Sustainable Raw Materials in Additive Manufacturing
By Corey Long and Clémentine Champagne, Arkema Additive manufacturing generally is considered to be a more environmentally responsible technology by enabling on-demand, local production, with the potential to reduce material waste and minimize the logistic footprint. The key to unlocking its full potential lies in the use of more sustainable raw materials. These innovations … [Read more...] about Sustainable Raw Materials in Additive Manufacturing
