Silicone-Based Defoamer for Paints and Coatings
Borchers® AF 1270 is a silicone-based defoamer and air release agent for solvent-based systems. This additive contains polysiloxane.
Benefits of Silicone-Based Defoamers and Air Release Agents
Borchers® AF 1270 is a mixture of fluorinated, modified polysiloxane diluted in butyl acetate. This defoamer solution improves surface leveling and has good binder compatibility. It has good gloss retention and low haze in formulated systems. As an air release agent, Borchers® AF 1270 supports fast air release of entrapped air on the film surface. This solution has little impact on film integrity.
Ideal applications include solvent-based 2K-polyurethane systems, unsaturated polyesters, alkyds, epoxies, and UV systems.
