BYK additive for increasing the surface energy of cured coatings

16 June 2014

Until now it has only been possible to either reduce the surface energy of cured coatings by adding silicone additives or to maintain its original level by adding acrylate levelling additives. Using BYK-3560 the surface energy of cured coatings can now be increased.

BYK-3560 is based on macromer technology, which, as a result of the combination of product properties, opens up new avenues in terms of surface modification. It increases the surface energy of cured coatings overall, especially the polarity resulting in an improvement in the adhesion of subsequent layers such as paints, lamination foils, adhesives, printing inks, etc.
This additive also provides better wetting of the cured coating and good levelling of subsequent layers. Additionally, it improves the levelling of the system in which it is being used. BYK-3560 does not influence the surface tension of the liquid coating and retains the high transparency of clear coats.

BYK-3560 is silicone- and fluorine-free and has 100% active substance. Its usage is recommended to a wide range of systems: aqueous, solventborne, UV-curable and high solid.
