Fluorine-free, silicone-containing additive for improving substrate wetting and leveling in aqueous systems and solvent-free UV coatings. BYK-3455 is used for aqueous and 100% UV flexographic inks for substrate wetting. Leveling can be substantially improved, particularly for UV and overprint varnishes. BYK-3455 is used in aqueous inkjet inks. Reducing the static and dynamic surface tension improves both substrate wetting and also jettability. Using BYK-3455 can also optimise ink filtering. BYK-3455 has low foam stabilisation and offers good hydrolytic stability. In UV inks, BYK-3455 improves leveling.
