Метилтриметоксисилан cas

Application:

Be used as a cross-linking agengt for RTV.

The most common alkoxy crosslinkers are methoxy or ethoxy silanes due to their high reactivity. The reaction precedes by nucleophilic substitution usually in the presence of acid or base catalysts. Alkoxides react directly with silanols or with water to produce silanols. The newly formed silanols can react with other alkoxides or self-condense to produce a siloxane bond and water. When an acid catalyst is used, protonation of the alkoxysilane increases the reactivity of the leaving group. When a base catalyst is used, deprotonation of the silanol forms a reactive silonate anion. The by-product of the reaction is an alcohol. Common metal catalysts for these reactions are alkoxytitanium derivatives and dibutyltin dicarboxylates

Be used in the production of silicone resins.

Filler Modifier.

D-20 is used mainly to render a wide range of surfaces and materials water repellent (e.g. mineral fillers, pigments, glass, cardboard). D-20 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 as a pigment treatment to aid in dispersion.
