Ethyltriacetoxysilane (ETAS). Synonym: Triacetoxy ethyl silane. 에틸트라이아세톡시실레인 Countertype of DowCorning 3-7110, Wacker ES 23, Hanse AC10 |
| Chemical Structure |
 |
| Introduction |
|
SiSiB® PC7950 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.

| Applications |
|
SiSiB® PC7950 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. SiSiB® PC7950 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.
