  Methyl Hydrogen silicone oil : Product performance
Because molecules containing active bonds Si - H, therefore, it can join in a variety of chemical reaction and has good film-forming performance;
It can reacted with the HO or R-OH bonds in the Alkali or lewis acid, and release H2.
It is easy to react with alkene compounds in the platinum and chromium compounds ;
When the temperature above 50 ℃, it can react with the compounds containing epoxy groups;
Its heat resistance is not better than dimethyl silicone oil, but its waterproof and moistureproof and anti-sticking performance is much better than dimethyl silicone oil;
Under the effect of metal salt catalysts, it will form hydrophobic membrane in a variety of material surface under low temperature crosslinking.   The main applications:
1 Ceramic anti-fouling, oil preventing , waterproof treatment.
2.The important intermediates of synthesising various modified silicone oil, Silicone Rubber.
3.Waterproofing agent and softening agent for natural and synthetic fabrics, silk, leather
4.Waterproof and anti-sticking agent for paper.
5.Waterproof and softening agent for glass fiber.
6 Hydrophobic agent and lubricant, anticorrosive&anti-sticking agent for cosmetic use oily liquid foundation   Packaging and shipping:
