Organosilicon: Chemical compound containing the SI-C bond and having at least one organic group attached directly to the silicon atom. As a basic material, organosilicon material has been widely used in construction, electronics, textile, light industry, chemical industry and other fields. In the field of waterproof plugging, common silicone materials are: silane, silicone solution, silicone emulsion, silicone powder, silicone emulsion, silicone sealant, silicone sealant.

In the field of waterproof plugging, common silicone materials are: silane, silicone solution, silicone emulsion, silicone powder, silicone emulsion, silicone sealant, silicone sealant.
The common feature of these materials is that they all have excellent water-repellent properties. That is, all manufacturers will be used to do a demonstration of the "lotus leaf effect."
Particularly easily confused with inorganic silicon are what are commonly referred to as silicone waterproofing agents. That's sodium methyl silicate or potassium methyl silicate.
The waterproof mechanism of sodium (potassium) methyl silicate is to form an insoluble waterproof resin film several molecules thick on the surface of the substrate, which is usually diluted with 8-10 times of water when used.
It is often used for waterproof and antifouling treatment of building materials and waterproof of exterior wall decoration. But the life of this material will not be long, especially under the exposure environment of ultraviolet ray irradiation, once the hydrophobic effect of the surface layer disappears, the waterproof performance of the material is also invalid.
Inorganic silicon: usually refers to sodium silicate, potassium silicate, lithium silicate, and other as the main agent, adding some additives compound from the waterproofing agent.
In the field of waterproof plugging, common inorganic silicon materials are: permanent liquid, water penetration crystalline waterproof material, sodium silicate, etc.
Its waterproof mechanism is usually dehydrate oneself or form crystals in the concrete wool stoma to block the passage so as to improve the concrete density, strength, impermeability and other indicators.
