Methyl Hydrogen Silicone Fluid RJ-202※MSDS Download ※TDS Download Inquiry
Synonyms: Polymethylhydrogen Siloxane Fluid; Poly methyl hydrogen siloxane; Methyl hydrogen silicone oil; Methyl hydrogen polysiloxane, Polymethylhydrosiloxane
Cas No: 63148-57-2
Methyl Hydrogen Silicone Fluid 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.
Poly methyl hydrogen siloxane 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.
The quality of RJ-202 has already been approved by some of the world's largest gypsum board manufacturers.
