BYK-S 732

BYK-S 732 is a solvent-free polyether-modified polysiloxane copolymer that prevents air entrapment and porosity in ambient-curing epoxy and polyurethane systems. It improves wetting of reinforcement materials such as glass fibers, carbon fibers, and silica sand, ensuring smooth, defect-free surfaces. Designed for reinforced and filled resin systems, it enhances processing efficiency and final coating quality.
