| Questions And Answer | Back Directory | [Introduction]
Ethyltriacetoxysilane (ETAS) is a clear to yellowish liquid with acrid odor of acetic acid (vinegar). It hydrolyzes in the presence of moisture (acetic acid is released) to form silanols, which can react with themselves to pro-duce siloxanes or bind to inorganic substrates.
It 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.
