SiSiB® WR2020 is a methylhydrogen silicone fluid in which some of the methyl radicals of dimethyl silicone fluid are replaced by hydrogen.
SiSiB® WR2020 is similar to MH-1107 (DowCorning), TSF-484 (Momentive), DF-1040 (Momentive), Rhodorsil H68 (Rhodia), SILRES BS 94 (Wacker) and KF-99 (ShineTsu).
A clear coating with good water repellency, mold releasability, and lubricity is obtained by baking this product onto the surface of various materials.
