n-Propyltriacetoxysilane CAS No:17865-07-5 C9H16O6Si

Main Applications

1.‌Silicone Rubber Crosslinking Agent‌: Used for the vulcanization and crosslinking of deacidified room-temperature-curing silicone rubber and acidic silicone sealants; it is often blended with methyl triacetoxysilane to prevent crystallization and enhance mechanical properties.

2.‌Synthesis Intermediates/Additives‌: Serves as a functional intermediate in silicone synthesis, participating in chain extension or modification reactions.

3.‌Property Correlation‌: Upon contact with water, it hydrolyzes to form acetic acid and undergoes a cross-linking reaction; therefore, it is suitable for acid-curing systems.‌‌

Storage Instructions

1.‌Environmental Requirements‌: Store in a sealed container in a cool, dry, and well-ventilated area. Strictly protect from moisture and water, and keep away from sources of fire and heat.

2.‌Recommended Temperature‌: Industrial-grade products can generally be stored at room temperature away from light; high-purity reagent-grade products are recommended to be refrigerated at 2–8°C, and it is advised to use nitrogen or argon purging to prevent moisture ingress.
