Main Applications

It's a basic raw material of defoamers and foam stabilizers, as well as addition pressure-sensitive adhesives and transparent reinforcing fillers.
Especially suitable to be applied in high temperature defoamer.
Especially in polyurethane processing technology, SF-201C can be used to prepare high-solid content release agent stock solution or solvent-based anti-adhesive agent, which has excellent mold release, avoids accumulation on the mold, and protects the smooth surface of molded parts.
