SiSiB® PC5131

Methyltrimethoxysilane

SiSiB® PC5131, MTMS chemical, an alkylalkoxysilane is an important component in sol-gel system. It is a colorless liquid. It hydrolyzes slowly in the presence of moisture (methanol is released) to form reactive silanols. These react further to produce oligosiloxanes and then poly- siloxanes.

It is the equivalent of Momentive's A-1630, Dow's Z-6070, Wacker's M1-TRIMETHOXY, Evonik's Dynasylan MTMS, ShinEtsu's KBM-13. For methyltrimethoxysilane price and other more details, please feel free to contact us.

Application

SiSiB® PC5131 organo sisib silicones are highly miscible with standard organic solvents, such as alcohols, hydrocarbons and acetone.

SiSiB® PC5131 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 SiSiB® PC5131 Methyltrimethoxysilane substantially.

SiSiB® PC5131 is used as an important component in sol-gel systems.

SiSiB® PC5131 alkyl alkoxy silane is also used in the production of silicone resins and condensation-curing silicone rubber.

[Filler Modifier] SiSiB® PC5131 Methyltrimethoxysilane is used mainly to render a wide range of surfaces and materials water repellent (e.g. mineral fillers, pigments, glass, cardboard). MTMS silane CAS 1185 55 3 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.

[Alkoxy Crosslinkers] The most common alkoxy silane crosslinking agents 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.
