Main Composition：Polymethylhydrosiloxane
CAS: 63148-57-2
Specifications:
Hydrogen content(%, m/m): 1.56—1.6
Viscosity（25℃mm²•Sˉ1）: 10-30
Density(25°C, g/cm3): 0.995-1.015
Refractive index(25°C): 1.390-1.410
Specialty: reactive silicone oil
volatile content（150℃•2h）≤3
Characters:
As the molecules contains active Si-H bond, it can participate in a variety of chemical reactions,it has good film formation property ;
It can react with the HO or R-OH,and release H2 at the presence of Lewis acid.
It reacts easily with vinyl compounds at the presence of platinum chromium compounds;
It can react with the compounds containing epoxy group as T﹥50℃
Its heat resistance is worse than dimethyl silicone oil,but its moisture-proof and anti-sticky properties is better than dimethyl silicone oil.
In the operation of metal salt catalyst,it can be crosslinked into waterproof film on the surface of various materials at the low temperature.
Usage：
1. Antifouling,oilproof, waterproof treatment agent for ceramic.
2. The important intermediates for the synthesis of modified silicone oil and silicone
