JS Cement-Based Waterproof Coating Reference Formulation

JS Cement-Based Waterproof Coating Reference Formulation

JS waterproofing coating (polymer-modified cementitious waterproofing coating) is a two-component, water-based building waterproofing material composed of a polymer emulsion (such as polyacrylate emulsion or ethylene-vinyl acetate copolymer emulsion) combined with inorganic powders such as cement. It combines the flexibility of organic materials with the durability of inorganic materials and is widely used in building waterproofing projects. The HQ series of additives launched by Haoqian Technology plays a key role in the JS waterproof coating system.
