Coatings field


Sodium Methyl Silicate is an inorganic silicate waterproof agent. In the coatings field, it is mainly used as a highly effective waterproof additive. It reacts with free calcium ions in the substrate (such as concrete and mortar) to generate a hydrophobic siloxane network, forming a permanent waterproof layer. Its small molecular structure can penetrate into the micropores of the substrate (depth up to 3-10mm), achieving "internal waterproofing" rather than surface sealing.
