107 Silicone Polymer 100000 cst is hydroxyl‑terminated polydimethylsiloxane, CAS 70131‑67‑8. This high‑viscosity 107 base polymer is developed for two‑component secondary insulating glass sealant. It has excellent miscibility with reinforcing fillers and alkoxy cross‑linking agents. After condensation curing, finished sealant shows low water vapor permeability, outstanding elastic recovery and anti‑ageing property, which protects insulating glass cavity and extends service life of hollow glass a

Product Detail

Product Overview

107 Silicone Polymer 100000 cst is hydroxyl‑terminated polydimethylsiloxane base polymer, CAS 70131‑67‑8. As high‑viscosity core raw material for secondary insulating glass sealant, it adopts strict control on viscosity and hydroxyl content for each batch. When compounded with special reinforcing fillers and neutral alkoxy cross‑linkers, it achieves low water vapor transmission performance. Rigorous quality testing meets mass‑production requirements of hollow glass deep‑processing manufacturers.

Key Features

100000 cst high viscosity customized for insulating glass secondary sealant
Precisely controlled hydroxyl groups for stable neutral condensation curing
Excellent compatibility with high‑loading reinforcing mineral fillers
Contributes to low water‑vapor‑permeability after complete curing
High elastic recovery to offset thermal expansion and contraction stress
Superior UV resistance and long‑term outdoor weathering stability
Low volatile substance, no adverse influence on insulating glass inner cavity
Stable batch‑to‑batch performance for continuous factory production

Main Applications

Two‑component secondary insulating glass silicone sealant
Edge sealing compound for hollow insulated glass units
Neutral condensation‑cure silicone for glass deep processing industry
Weather‑resistant sealing for building curtain wall glass assembly
Custom silicone formulations requiring low moisture permeability
High‑elasticity construction sealing silicone compound

Processing Suggestions

Carry out feeding, kneading and dispersion under strictly moisture‑isolated environment. Formulate with reinforcing fillers, alkoxy silane cross‑linking agent and organometallic catalyst. Adjust filler proportion to satisfy modulus, hardness and water vapor transmission indicators. Prevent moisture invasion during full production cycle to avoid curing defects.

Storage & Packing

Packed in sealed 200kg iron drum. Store in cool, dry and ventilated warehouse. Keep drum tightly sealed. Keep away from humidity, high temperature and direct sunlight. Reseal drum promptly after partial material discharge. Follow recommended storage conditions to retain polymer reactivity and valid shelf‑life.
