Phenyltriacetoxysilane

CAS Number
18042-54-1

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. The phenyl group slows cure and improves thermal stability of the cured sealant.
