The emulsion used in the preparation of polymer cement waterproof coating UV aging has a significant capacity and a certain thermal aging capabilities. Nano-SiO_2 optimum dosage is 1.0%. Also studied montmorillonite prepared and crosslinking compound and organic montmorillonite and processing of nano SiO_2 composite graft-modified polymer cement-based waterproof coating. The results show that: the composite film modified to increase the tensile strength and water resistance, UV aging resistance and heat aging resistance than a single waterproof coating modified under the same conditions. Polymer cement-based waterproof coating Features: Construction is simple: a cement-based products waterproof coating, waterproof layer directly above the paving tiles polymer cement-based waterproof coating for sale, plaster or paint; environmental protection: non-toxic, can Brushing drinking water directly to the pool; Hazard: Non-flammable material polymer cement-based waterproof coating how, non-corrosive; moist areas can Construction: As the paint must penetrate through the role of water in the end internal polymer cement-based material Wholesale waterproof coating, therefore, moist areas can construction, such as concrete dry, must be soaked with water before construction. Polymer cement-based waterproof coating for sale, long a source (certified), waterproof coatings provided by Weifang City for the source waterproof material Limited. Weifang City for the source of waterproof material Ltd.
