Application
Methyltrimethoxysilane
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 otheralkoxides 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 dibutytin dicarboxylates.
