Main ingredients: polyurethane resin, calcium carbonate, additives, etc.
Features:
Water-based paint refers to an environmentally friendly paint that uses water as the main solvent or dispersion medium, in which more than 80% of the volatile components are water, without benzene, toluene, xylene, formaldehyde, free TDI, harmful heavy metals, non-toxic and non-irritating The smell is harmless to the human body and does not pollute the environment. The waterborne polyurethane resin coating produced by our company is a one-component waterborne anionic polyurethane emulsion, which can be directly dissolved in water in the liquid, cures at room temperature, does not require a curing agent, and is waterproof and solvent resistant after drying.
This product of our company can be used for waterproof coatings, roofs, basements, civil air defense projects, kitchens and bathrooms, tunnels, bridges, pools and other easy-to-seepage projects, as well as caulking materials for building structures. Wood floors, cement boards, asbestos products, glass steel products, ceramics Bonding of products, floor tiles, etc.
