Product Overview

100cst Methyl Hydrogen Silicone Oil (CAS 63148-57-2) is polymethylhydrosiloxane (PMHS) containing reactive Si-H groups. It is a high-efficiency crosslinker specially formulated for addition cure silicone systems. With stable molecular structure and excellent compatibility with vinyl silicone polymers, it participates in hydrosilylation reaction to form a three-dimensional silicone network, extensively adopted in various addition-type silicone materials.

Key Features

Stable silicon-hydrogen activity, consistent crosslinking performance
Great miscibility with vinyl silicone base materials
Moderate viscosity for simple stirring and homogeneous mixing
No harmful by-products generated during curing
Improve elasticity, thermal stability and mechanical strength of silicone finished goods

Main Applications

Crosslinking agent for addition cure liquid silicone rubber
Raw material for electronic silicone potting gel
Formulation of transparent silicone encapsulant
Cross-linking component for silicone coating & silicone adhesive

Usage Guidance

Mix fully with vinyl silicone polymer under platinum catalyst system. Adjust addition amount based on target hardness and curing requirements. Keep away from tin catalysts, amines and heavy metal compounds, which will lead to premature gelation.

Storage & Package

Keep sealed and store in cool, dry, ventilated warehouse, far from high temperature and open flame. Standard packaging: 25kg plastic drum, 200kg iron drum. Shelf life: 12 months under appropriate storage conditions.

Service Support

Testing samples can be provided. Stable bulk supply and technical formulation guidance are available for silicone manufacturers. Feel free to contact us for TDS and competitive factory quotation.
