This product is: magnesium fluosilicate
Molecular formula: MgSiF6?6H2O
Molecular weight: 274.48
Danger number: 2853
Risk Level: 6.1
Physicochemical properties: white rhombic or acicular crystals, odorless, relative density is 1.788, melting point is 120 C. It can be weathered and lose crystalline water. It is soluble in water, dilute acid, hydrofluoric acid and alcohol. The aqueous solution is acidic. The corresponding fluoride and silica can be formed when reacting with alkali. Poisonous.
Usage: Mainly used as hardener and waterproof agent to improve hardness and strength of concrete. It can also be used for fluoride weathering on the surface of silica buildings and as pesticides.

Note: At present, the content of magnesium fluosilicate produced by the company is about 99%, with 80 meshes, 100 meshes and 200 meshes. Magnesium fluosilicate can improve many properties of concrete and cement products. It is a good hardening agent. The surface of agglomerated and dry concrete treated with it can increase wear resistance and reduce dust. The fission erosion of concrete can be inhibited by 3% solution treatment and 12-20% aluminium fluosilicate solution treatment.
