Product performance
Because the molecule contains active Si-H bonds, it can participate in various chemical reactions and has good film-forming properties;
In the presence of alkali or Lewis acid, it can react with HO or R-OH to release H2;
It is easy to react with olefinic compounds in the presence of platinum chromium compounds;
When T>50℃, it can react with compounds containing epoxy groups;
Its heat resistance is not as good as that of dimethyl silicone oil, but its water-repellent, moisture-proof and anti-stick properties are better than that of dimethyl silicone oil;
Under the action of metal salt catalyst, it can be cross-linked at low temperature to form a hydrophobic film on the surface of various substances.
