Byk 354 Surface Additive

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

Where is Byk 354 Surface Additive used?

• Industrial and decorative coatings: improved flow and leveling
• UV-curable and radiation-curable inks: reduced surface tension
• Adhesives and sealants: substrate wetting and control of surface slip and uniformity
• Plastic coatings and packaging inks: consistent print quality and surface finish on high-speed lines
• It prevents cratering, orange peel and Bénard cell formation without affecting recoatability or intercoat adhesion.

Good to know: Effective in both solvent-borne and high-solids systems. No specific regulatory grade designations apply; positioned as a technical-grade performance additive for industrial end uses.

Commercial specifications

• Standard packaging sizes for industrial procurement volumes, including drums and smaller containers
