Additives to Improve Surface Performance of UV Coatings Utilizing Cross-Linkable, Nanoparticle Dispersions or Micronized Wax
By Mike Toth, BYK USA In today’s throwaway society, a product that demonstrates quality and longevity is not only an anomaly, but a seemingly fortuitous outcome. In many industries, supply chain disruptions and logistical challenges have impacted the ability to obtain necessary products. Worst-case scenarios from supply breakdowns can lead to product recalls or poor-quality … [Read more...] about Additives to Improve Surface Performance of UV Coatings Utilizing Cross-Linkable, Nanoparticle Dispersions or Micronized Wax
Hurdles and Solutions to Matting of UV Wood Coatings: Part 1
By Hossein Riazi and K. Michael Peck, Evonik Corporation, USA Achieving a matte finish in 100% solids energy-curable coatings can be a challenge. Viscosity increases with traditional particle matting agents, and minimal film shrinkage of the binder creates hurdles in efficiently building a suitable matte surface structure. In addition, getting a deep-matte finish in … [Read more...] about Hurdles and Solutions to Matting of UV Wood Coatings: Part 1
