Ethyltriacetoxysilane

CAS Number
17689-77-9

Description

Acetoxy functional silane crosslinker for one-component condensation-cure silicone sealants. Fast skin-over and through-cure; releases acetic acid, so it is not recommended on concrete, marble or bare metals sensitive to acid. Releases acetic acid more slowly than the methyl grade, giving a longer open time.
