Countertype of Wacker's SILRES BS-94, DowCorning's MH-1107, Momentive's TSF-484 & DF-1040, Rhodia's Rhodorsil H68 and ShineTsu's KF-99.


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.

Applications

SiSiB® PF2020 may be used for water repellent (hydrophobing) treatment of plasterboard and plaster blocks.

SiSiB® PF2020 may be used for treatment of powders and granular materials to make them water repellent.

SiSiB® PF2020 may be used for treatment of dry-spayed substances (like extinguisher powders, various fillers) to make them free flowing and to reduce caking.

SiSiB® PF2020 may be used for impregnation of cylinder head gaskets in order to improve their permeability properties.

SiSiB® PF2020 may be used for water repellent treatment of textiles (flat, natural, synthetic or mixed, knitted, non woven fabrics) either in a solvent system or in an aqueous emulsion using an appropriate technique.
