Substrate Wetting and Anti-Crater Additives

Specially engineered for coatings and inks, our Wyncoat® Substrate Wetting and Anti-Crater Additives excel in surface tension reduction and deliver outstanding substrate wetting performance.

Compatible with a wide range of formulation systems, including water-based (WB), solvent-based (SB) and UV-curable (UV), it effectively addresses poor wetting issues on challenging low surface energy substrates.

These additives completely eliminate craters, shrinkage and uneven surface defects during film formation, creating flawlessly smooth, uniform and premium coating surfaces.
