Byk 354 Surface Additive

BYK 354 Surface Additive (CAS 919533-63-4) is a silicone-free, acrylate-based surface control additive used to reduce surface tension and improve leveling in coating and ink formulations.

It prevents surface defects such as cratering, orange peel, and Bénard cell formation without affecting recoatability or intercoat adhesion. In industrial and decorative coatings, it improves flow and leveling.

This additive is effective in both solvent-borne and high-solids systems, delivering smooth, defect-free film surfaces. UV-curable and radiation-curable ink formulations benefit from its ability to reduce surface tension.

It improves substrate wetting across difficult surfaces and helps control surface slip and uniformity during application in adhesive and sealant systems. This ensures consistent quality across various industrial applications.

Plastic coatings and packaging inks use it to ensure consistent print quality and surface finish across high-speed production lines. It is a versatile solution for demanding manufacturing environments.

The product is supplied as a liquid solution, ready for direct incorporation into formulations. It is available in standard packaging sizes suited to industrial procurement volumes, including drums and smaller containers.

No specific regulatory grade designations apply; the product is positioned as a technical-grade performance additive for industrial end uses. It meets the rigorous demands of modern chemical processing and coating.
