Polyurea Protective Coatings

Steel Structure Anti Uv Polyurea Spray Coating Protective Anti Corrosion

Product Details

Descriptions


The common outdoor anti-corrosion protective coating is usually turns yellow after three months, pulverization after six months when it exposed to suffer the sun’s ultraviolet irradiation. It not only influence the appearance, but also lower the protective performance of the coating.Two components industrial anti-corrosion protective UV resistance top coating developed by our company can bear long- term irradiation of sunshine, with high weather resistance performance no yellowing, no pulverization and peeling off after long term outdoor use. It has been widely used and well received by customers in many districts in the Americas and Europe.



Characteristics


The coating film is dense, tough, full bright, colorful without yellowing and pulverization, anti-aging and excellent weather resistance and color retention and decoration effect. Film coating has high adhesive strength, nice physical performances, high properties of wear resistance, impact resistance, wet resistance, anticorrosion salt spray resistance performance and stable chemical resistance. It has good compatibility with other polyurethane, epoxy, chlorinated rubber, alkyd, phenolic paintings.
