Under the action of metal catalysts, hydrogen-containing silicone oil can be cross-linked at an appropriate temperature to form a waterproof film on the surface of various substrates. It is widely used in fabrics, fire extinguishing agents (dry powder), paper, metal, leather, wood, glass, cement, Ceramic, marble waterproofing agent, anti-sticking agent or anti-corrosion agent, etc.
The hydrogen-containing silicone oil is catalyzed by a metal salt to form a film, which requires a certain temperature. The reaction can be cured at room temperature with a strong base.
The catalytic ability of metal salts is relatively weak, and it takes a long time for hydrogen-containing silicone oil to cure at room temperature. Heat it as much as possible, generally to about 100°C, at this time the curing speed is greatly accelerated.
In summary, the formation of membranes under the catalysis of hydrogen-containing silicone oil metal salts can only be formed at high temperatures.
