Methyltriethoxysilane Chemical Properties,Usage,Production

Description

Methyltriethoxysilane is an alkylalkoxysilane. It is a clear, colorless liquid with an odor characteristic of alcohols. It hydrolyzes slowly in the presence of moisture to form reactive silanols. These react further to produce oligosiloxanes and then polysiloxanes.
As a Filler Modifier, Methyltrimethoxysilane is used mainly to render a wide range of surfaces and materials water repellent (e.g. mineral fillers, pigments, 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. It is also used in the production of silicone resins and condensation-curing silicone rubber, used as an important component in sol-gel systems.
As one of the most common Alkoxy Crosslinkers, Methyltrimethoxysilane has high reactivity that precedes by nucleophilic substitution usually in the presence of acid or base catalysts.

Chemical Properties

Colorless clear liquid

Uses

Methyltriethoxysilane is used in production of silicone polymers or silicone resin. It is used in non-metal surface treatment, non-aqueous polymer preparation, manufacture of semi-conductors, coatings and sealants. It finds application as cross linking agent and an adhesion promoter.

Flammability and Explosibility

Flammable
