107 Polymer Raw Material for Structural Glazing Sealant is hydroxyl‑terminated polydimethylsiloxane with CAS 70131‑67‑8. This high viscosity 107 base polymer is engineered for structural glazing sealant. It achieves excellent reinforcement effect with high‑performance fillers. After cross‑linking, finished sealant features high cohesive strength, good adhesion and outstanding anti‑ageing property, suitable for curtain wall structural glazing bonding and high‑load building sealing applications.

Product Detail

Product Overview

107 Polymer Raw Material is hydroxyl‑terminated polydimethylsiloxane, commonly known as 107 silicone rubber base polymer with CAS number 70131‑67‑8. This condensation‑cure PDMS is developed as core raw material for structural glazing sealant. Accurate hydroxyl value and stable viscosity guarantee predictable cross‑linking reaction. When compounded with reinforcing fillers and neutral alkoxy cross‑linking agents, it provides reliable mechanical performance for structural bonding applications. Strict quality management ensures stable batch performance for large‑scale architectural sealant manufacturing.

Key Features

Formulated for high‑performance structural glazing sealant
Precisely controlled hydroxyl terminal groups for steady condensation curing
Excellent wetting and dispersing capacity for reinforcing mineral fillers
Achieves high modulus, high tensile strength and strong cohesive property after curing
Reliable adhesion to glass, aluminium and other building substrates
Outstanding UV stability and long‑term outdoor weathering resistance
Low volatile impurities, excellent batch‑to‑batch repeatability

Main Applications

Curtain wall structural glazing silicone sealant
High‑strength neutral structural bonding sealant
Heavy‑load architectural assembly sealing
High‑modulus condensation‑cure RTV silicone compound
Construction silicone for glass‑metal composite bonding
Custom high‑performance structural silicone formulations

Processing Suggestions

All feeding, kneading and dispersion processes must be completed under moisture‑isolated workshop environment. Mix with reinforcing fillers, neutral cross‑linker and organometallic catalyst. Adjust filler loading and auxiliary additives according to target modulus, tensile strength and adhesion requirement. Prevent moisture ingress throughout production to avoid premature cross‑linking.

Storage & Packing

Store in cool, dry and ventilated warehouse. Keep iron drum fully sealed. Avoid moisture exposure, high temperature and direct sunlight. Reseal drum tightly immediately after partial material taking. Follow recommended storage conditions to maintain polymer reactivity and valid shelf‑life.
