107 Silicone Raw Material for Acetic Silicone Sealant Production is hydroxyl‑terminated polydimethylsiloxane with CAS 70131‑67‑8. It is dedicated base polymer for acetoxy cure sealant system. Controlled hydroxyl content brings stable curing speed. It shows good miscibility with calcium carbonate, fumed silica and other fillers, delivering good elasticity and adhesion for finished acetic silicone sealant, widely used in mass production of indoor acetic‑type sealing products.

Product Detail

107 Silicone Raw Material for Acetic Silicone Sealant Production CAS 70131‑67‑8

Product Overview

107 Silicone Raw Material is hydroxyl‑terminated polydimethylsiloxane base polymer, CAS 70131‑67‑8. Formulated as core raw material for acetic silicone sealant, this condensation‑cure PDMS features precisely adjusted hydroxyl terminal groups. It matches well with acetoxy silane cross‑linkers. Strict quality control stabilizes viscosity and reactivity, ensuring uniform extrusion property, curing behaviour and finished sealant performance in large‑scale manufacturing.

Key Features

Customized for one‑component acetic silicone sealant formulation
Stable hydroxyl value to guarantee consistent cross‑linking reaction
Outstanding compatibility with calcium carbonate and silica fillers
Smooth mixing and dispersion during sealant kneading process
Stable curing rate under normal workshop conditions
Good elasticity and surface property of cured acetic sealant
Low impurity content, reliable batch‑to‑batch repeatability

Main Applications

One‑component acetoxy cure acetic silicone sealant
General‑purpose indoor construction sealing products
Domestic joint filling acetic silicone adhesive
Condensation‑cure RTV silicone rubber base material
Mass production formula for acetic‑type sealing compound

Processing Suggestions

Complete feeding, kneading and dispersion under moisture‑free working environment. Combine with acetoxy silane cross‑linking agent and organotin catalyst. Adjust filler loading according to target extrusion rate, hardness and modulus. Strictly prevent moisture contamination throughout the whole production cycle to avoid premature curing.

Storage & Packing

Store in cool, dry and ventilated warehouse. Keep iron drum tightly sealed at all times. Keep away from humidity, high‑temperature sources and direct sunlight. Reseal drum immediately after partial material discharge. Proper storage condition protects product reactivity and ensures full shelf‑life.
