Chemical Structure
Introduction
SiSiB® PF2020 is a methylhydrogen silicone fluid in which some of the methyl radicals of dimethyl silicone fluid are replaced by hydrogen.
A clear coating with good water repellency, mold releasability, and lubricity is obtained by baking this product onto the surface of various materials.
