Product Information
Ethyltriacetoxysilane ethyltriacetoxysilane, ETAS silane, does not contain any additives such as catalysts, stabilizers or adhesion promotion agents. If required, these additives have to be added to the sealant formulation separately.
Ethyltriacetoxysilane is used as curing agent in acetoxy crosslinking RTV-1 sealant formulations. Within the curing reaction acetic acid is produced as a byproduct. Therefore, the corrosive reaction of the byproduct with substances like marble or iron has to be taken in consideration when using acetate crosslinkers.
When this compound is exposed to moisture some acetoxy groups are hydrolyzed and self-condense or react with other acetoxy and rapid crosslinking takes place. Acetic acid formation is one of the driving forces of this reaction.
