Uses: 
Sodium methylsiliconate is a one-component curing synthetic polymer waterproofing agent material, the mechanism of which is to generate methylsilanol under the action of water and carbon dioxide, further combine and chemically react with building materials to form insoluble waterproof polymer compound film. This membrane has the advantages of waterproof, impermeability, moisture, rust, anti-aging, anti-pollution, breathable and so on. And has excellent weather resistance and durability, no rust to the steel bar.
