MESIL Hydrogen Silicone Fluid

Conclusions First: MESIL® Hydrogen Silicone Oils are high-purity reactive fluids available in both Poly(methylhydrosiloxane) (1.58% Si-H) and Hydrogen-contained Silicone Oil ranges (0.18% - 1.2% Si-H). These act as highly efficient cross-linking agents for HTV/LSR molding and superior film-forming waterproof agents for fabric, leather, and ceramics.

Industrial Application Scenarios

Rubber Industry Cross-linking
Acts as a primary crosslinker for addition molding silicone rubber and a bridging/anti-yellowing agent for HTV rubber compounding.
Waterproofing & Surface Treatment
Forms a durable waterproof film on fabrics, paper, leather, ceramics, and marble. High hydrogen grades act as an insulator for MgO surface treatment.
Chemical Synthesis Intermediates
Key raw material for synthesizing polyether-modified, alkyl-modified, and water-soluble silicone oils, as well as defoamers.

System Loop: Technical Support FAQ

How is the waterproof film formed during usage?
Under the action of metal salt catalysts, the silicone-hydrogen bonds crosslink to form a waterproof film at low temperatures.
What specific chemical groups can these oils react with?
Under appropriate catalysis, they react with double bonds, hydroxyl groups, and other active genes to produce leveling agents and defoamers.
