Energy Curable Resins

Energy curable solutions for low gloss applications

Enhancing the natural beauty of substrates

Ecological awareness, lifestyle changes, and curb appeal are driving the need for surface finishes that preserve, but also emulate the beauty of nature in both naturally occurring and artificial substrates. Additionally a substrate’s finish plays an integral part in the commercial value by adding performance features to the final product. Therefore interest in “high performance ultra-low gloss finishes” is increasing, which have historically been challenging to achieve.

For ultra matt finishes without matting agents – Excimer curing with EBECRYL® 266 and 5130

Resins for Excimer curing have been developed to achieve low gloss and high-performance profiles. Excimer curing technology can offer a very low gloss level (~ 2GU’s at 60°). Prior to the UV curing, a 172nm excimer light is used to irradiate the thin surface layer that shrinks and forms a micro-folded structure, which creates a dull/matt effect due to light refraction. The liquid UV coating can be applied by roller, spray, or curtain coater to have a fully cured low gloss surface.

 Main product features:

  • Exceptionally high chemical and mechanical resistance

  • Ability to achieve ultra-matte levels (~ 2GU’s at 60°)

  • Excellent scratch, polishing, and abrasion resistance, with improved stain resistance

  • No need for matting agents (silica-free formulations)

  • Improved performance with soft touch effect, anti-fingerprint properties
