Sodium Methylsiliconate
Sodium Methylsiliconate is mainly used for surface treatment of stone, brick, ceramic, concrete, cement mortar, perlite, gypsum and gypsum board, wood, etc. It can increase water resistance, reduce water absorption, reduce weathering, improve weather resistance, and seal. The role of moisture protection can also be used as an additive to Sodium silicate.

| Uses | 1. Widely used in roofing, internal and external walls, floors, bathrooms, kitchens, basements and warehouses of waterproofing and moistureproofing as well as reinforced concrete structures to block penetration and prevent infiltration; 2, used for underground human defense projects: such as culverts, bridges, dams, tunnels, large hydroelectric power stations, water diversion projects, in order to reduce water erosion and prevent weathering; 3、Used in all kinds of pools: such as swimming pools, water purification pools, sewage pools, water towers; 4、Used in the impregnation of high water absorption inorganic aggregates: such as perlite boards, roof tiles, cement bricks, lightweight brick finishes for high-rise buildings, asbestos, inorganic fabrics, thermal insulation materials, etc., so as to provide significant waterproofing and moisture-proofing effects; 5、Used in water-soluble architectural coatings for waterproofing, color protection, prevention of pollution, prevention of aging, has been widely used in exterior wall finishes; 6、Used in latex paint, water glass, 107 glue additives, which can make it have obvious water-enhancing, and can maintain stable bonding strength; 7、Used in oil drilling, it can adjust the viscosity and density of mud, which can effectively prevent the drilling well from collapsing and improve the drilling rate; 8、Used in oil wells to open the pump at the later stage and inject into the oil extraction layer to prevent the collapse of the crustal skeleton of the oil extraction layer, making the oil farther away from the oil wells more smoothly extracted; 9、It is used for other special purposes to reduce water absorption and impermeability and waterproof. |
