BYK-UV 3500

Crosslinking, silicone-containing surface additive for radiation-curable printing inks, coatings and adhesives with a considerable reduction in surface tension. Very good substrate wetting and tape release, increases the surface slip and improves leveling. Due to its high surface activity, BYK-UV 3500 accumulates on the surface of the coating. Its acrylic functionality enables it to be incorporated in the polymer network and therefore to be anchored permanently to the coating surface. The additive provides high surface slip and improves leveling and substrate wetting. BYK-UV 3500 is particularly recommended for all non-aqueous, radiation-curable flexographic, offset and screen printing inks, also for radiation-curable overprint varnishes.
