Polymer-cement waterproof coating is a kind of two-component waterproof coating composed of synthetic polymer emulsion and various additives, which is composed of liquid and matching powder. It is a kind of waterproof material with high elasticity of synthetic polymer materials and good durability of inorganic materials. It has the characteristics of rigidity and flexibility, and has the extensibility of polymer coating film, water repellency, and high strength of hydraulic cementing material. Good water resistance, easy to wet base bonding Good flexibility, can resist the slight vibration of the building structure and a certain degree of displacement, and can be applied on the wet base and firmly bonded Water-based materials, non-toxic and harmless, non-polluting are environmentally friendly mater.
