Industrial Organosilicones

Methyltrimethoxysilane (CAS 1185-55-3) is an alkyl silane coupling agent manufactured in China, supplied by professional Chinese manufacturer for filler modification, water repellency, and silicone resin and rubber applications

CAS No.
1185-55-3

Silane miscible with alcohols, hydrocarbons and acetone; hydrolyses to silanols and is used as a coupling and crosslinking agent.

Packed with 5L, 20L or 210L plastic/steel drum, 1000L IBC container, or according to customer’s requirement.

Product NameMethyltrimethoxysilane
Other NamesA-163
Z-6070
Dynasylan MTMS
CM9100
CAS No.1185-55-3
EINECS No.214-685-0
Structure1185-55-3
Appearance:Colorless transparent liquid
Boiling Point (°C)102-104
Flash Point (°C)11
Applications:Highly miscible with standard organic solvents,such as alcohols, hydrocarbons and acetone.
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 its substantially.
(Filler Modifier) Methyltrimethoxysilane used mainly to render a wide range of surfaces and materials water repellent (e.g.mineral fillers,pigment,glass cardboard). It 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.
Itis also used in the production of silicone resins and condensation-curing silicone rubber.
Packing:Packed with 5L, 20L or 210L plastic/steel drum, 1000L IBC container, or according to customer’s requirement.
