Description
Dimethylsilanediol is an organic intermediate, a white to off-white solid, which can be obtained by the reaction of silicon powder and methyl chloride gas to obtain dimethyldichlorosilane, and then hydrolyzed. Its melting point is 101 ° C, boiling point is 122.2 ± 23.0 ° C, and density is 1.097 g / cubic centimeter. The upstream raw materials of dimethylsilanediol include 1-Disiloxanol, 3-methoxy-1,1,3,3-tetramethyl-, 1,1,3,3-tetramethyldisiloxane-1,3-diol, 1,1,3,3,5,5-hexamethyltrisiloxane-1,5-diol, 2,2,4,4,6,6-Hexamethylcyclotrisilazane, DimethyldimethoxysilaneDiethoxydimethylsilane. Dimethylsilanediol is an important monomer of commercial compounds and can be used as a hydrophobic agent for silicon oxide and other oxidized metal surfaces.

Dimethylsilanediol Use and Manufacturing
1,1-Dimethylsilanediol is the monomer of an important class of of commercial compounds called PDMS. Dimethylsilanediol is useful as a hydrophobization of oxidized silicon and other oxidized metal surf aces and compare the wetting properties of modified solids with those of conventionally modified surfaces.
