A-163 | Z-6070 | KBM-13 | MTMS | N.A |
The Physical Properties
Product No.: Siwin-931
Chemical Name: Methyltrimethoxysilane
CAS NO.: 1185-55-3
EINECS NO.: 214-685-0
Formula: C4H12O3Si
Appearance: Colorless Transparent Liquid
Density(ρ20℃，g/m³）： 0.9500±0.0050
Refractive Index( n 25℃ ): 1.3695±0.0050
Purity(by GC,%): 99 min; 99.5 min (Electronic Grade)
Applications
Siwin-931 is highly miscible with standard organic solvents, such as alcohols, hydrocarbons and acetone.
Siwin-931 is practically insoluble in neutral water and reacts only slowly to form silanols and higher condensation products.
Addition of a hydrolytic catalyst (inorganic/organic acids, ammonia or amines) accelerates the hydrolysis of Siwin-931 substantially.
(Filler Modifier) Siwin-931 is used mainly to render a wide range of surfaces and materials water
repellent (e.g.mineral fillers, pigment, glass cardboard). Siwin-931 may be used pure or in solution to treat fillers, using suitable mixing equipment.It may be necessary to first pre-treat the substrate with water and/or a catalyst.
Siwin-931 is also used in the production of silicone resins and condensation-curing silicone rubber.
