Dynasylan MTES, an alkyltrialkoxysilane, is an important component in sol-gel systems.
In some sol-gel applications Dynasylan MTES is partially hydrolyzed to form a preproduct that can be further crosslinked using temperature.
Dynasylan MTES is a colorless, low-viscosity liquid. Use requires acid- or alkali-catalysed hydrolysis. Dynasylan MTES is regarded as trifunctional since all three alkoxy groups are able to participate in this reaction.
Additionally Dynasylan MTES contains a methyl group that adds organic character to the products. Hydrolysis leads to silanol groups which, in a subsequent condensation reaction, form very stable siloxane bonds (-Si-O-Si-).
