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.

Battery Applications

MESIL Hydrogen Silicone Fluid in Lithium Battery

Hydrogen-functional silicone is the crosslinker (Part B) in two-component addition-cure thermal interface materials. SEMITECH offers multiple architectures so TIM compounders can dial in crosslink density and final modulus to match their cell-to-cooling-plate gap geometry.

TIM Crosslinker for Battery Modules

Si–H functional silicone reacts with vinyl PDMS under platinum catalysis to form addition-cure elastomer TIMs — no byproducts, no cure shrinkage.
