Methanesiliconic acid sodium salt CAS 16589-43-8

Methanesiliconic acid sodium salt is an organic compound and a new rigid building waterproof material with good permeability and crystallinity. The silanol groups in its molecular structure react with the silanol groups in silicate materials to dehydrate and crosslink, thereby achieving the "reverse capillary effect" to form an excellent hydrophobic layer, and at the same time has the functions of micro-expansion and increasing density. It is used as a waterproofing agent for concrete, limestone, gypsum products, red bricks, sandstone, plaster, plaster, new bricks and tiles, etc. It can also be used as an additive for mortar.
