Description

Chemical name: Polymethylhydrogen Siloxane Fluid; Methylhydrogensiloxane; Methyl Hydrogen Polysiloxane;

Equivalent Brand: Dow Corning 1107; Wacker BS94;TSF484;

CAS No: 63148-57-2

Polymethylhydrosiloxane RJ-202 is nontoxic and insipid. As there are fair quantity of relatively active Si-H bonds inthemolecule, under the action of catalysts it can react with chemicals containing active groups, such as double bonds or hydroxyl groups.

This product can be converted into film and used to produce a resilient waterproof coating on various materials by using metal salt catalyst at low temperature. It equips itself with outstanding water repellent property which prevents damage due to moisture, as well as mildew and rust development. Besides, its high vapor permeability allows the material to breathe and let water, vapor escape to the outside without causing damage.
