BYK Surface Treatment Agent

The BYK surface-active agent  series integrates polyacrylate and silicone-modified technologies to address critical challenges in coatings, inks, and adhesive systems. Designed for solvent-based, aqueous, and UV-curable formulations, these additives enhance substrate wetting, eliminate surface defects, and improve flow uniformity while maintaining compatibility with thin or thick film applications.

Key variants in the series leverage tailored molecular architectures to balance surface tension reduction and optical clarity. Their low dosage requirements ensure minimal impact on viscosity or intercoat adhesion, supporting, printing, and roll-coating processes. Applications span automotive OEM coatings, packaging inks, and industrial adhesives, where thermal stability and defect-free finishes are prioritized.
