What is Propylsilanetriyl triacetate?
Propylsilanetriyl triacetate (CAS 17865-07-5) is an organosilane monomer used as a crosslinking agent and surface modifier in silicone-based systems.
Where is Propylsilanetriyl triacetate used?
- Adhesives, sealants and elastomers: crosslinker in acetoxy-cure silicone systems
- Coatings: substrate wetting and durability on concrete, stone and treated metals
- Electronics: encapsulant and potting compound formulations with controlled cure rates
- Building and construction: silicone sealants for glazing and façade work
- On hydrolysis it releases acetic acid and generates a reactive propylsilanetriol intermediate.
Good to know: Buyers should confirm purity specifications and moisture-sensitive handling requirements with the supplier prior to ordering. Proper storage is essential to maintain the chemical integrity of this reactive monomer.
