Produktbeskrivning

In addition to the general properties of dimethyl silicone oil, methyl hydrogen-containing silicone oil can participate in a variety of chemical reactions due to the active Si-H bond in its molecular structure, and has good film forming properties. In the presence of substances such as base or Lewis acid, it can react with water or alcohol and be released
Hydrogen. In the presence of platino-chloric acid, it is easy to react with alkenes. When the temperature is greater than 50 ° C, it can react with compounds containing epoxy groups. The heat resistance of methyl hydrogen-containing silicone oil is not as good as that of dimethyl silicone oil, but its water-repellent, moisture-proof and stickproof properties are better than that of dimethyl silicone oil.

Ansökan

Methyl hydrogen-containing silicone oil can be transferred at low temperature to form a waterproof film with good hydrophobic effect, large contact Angle and durability on the surface of various substrates, which is widely used in industrial sectors such as textile, paper making, leather and construction. The treatment of fabric with methyl hydrogen-containing silicone oil can not only improve its tear strength, wear resistance, wrinkle resistance and stain resistance, but also greatly improve the ironing resistance and sewing property, and can achieve the purpose of complete waterproof without losing the original permeability. In addition, methyl hydrogen-containing silicone oil has better anti-stick properties than dimethyl silicone oil, so it is widely used as a release agent in the rubber and plastic industry, paper and packaging materials anti-stick agent. For example, the rubber products factory uses methyl hydrogen-containing silicone oil as an automobile inner tube release, which can be used continuously for 1 to 2 weeks. The optical glass coated with methyl hydrogen-containing silicone oil not only has superior light transmittance, but also has excellent anti-mildew and moisture-proof properties. Methyl hydrogen silicone oil can also be used as an anti-rust agent for metals.
