BYK-UV 3505

Cross-linkable surface additive for radiation curable systems for improving substrate wetting, scratch resistance, and easy-to-clean properties. BYK-UV 3505 improves substrate wetting and the leveling of 100%, UV-curing overprint varnishes. As a result of the strong reduction in surface tension, this product is primarily extremely well suited to wetting critical substrates and to conventional offset inks. The additive also causes a reduction in the coefficient of friction (COF) and a good tape release effect. The use of BYK-UV 3505 leads to an increase in gloss. The good compatibility with standard binders enables highly transparent overprint varnishes to be produced.
