SWD9604 water based exterior wall anticorrosion waterproof decoration coating

Descriptions                

Many varied kind of exterior wall coatings exist in the world construction market. The traditional solvent containing exterior coating is replaced by water base coating in the European and American market. The solvent type building coating cures by volatilizing solvent and generates much harmful gas damaging Ozonosphere. SWD Urethane Co., USA developed one component water base environment friendly exterior wall coating for safety and Eco friendly, it gained much attention of customers once entered market.

Characteristics              SWD Urethane CO., USA developed one component room temperature cure water base exterior wall anticorrosion waterproof decoration coating in the 1980s. The coating is green Eco friendly, safe and solvent free, with no harmful gas volatile during application. The coating has been widely applied in the building circles after launched and gained good social and economy effect. It has smooth and flat appearance, dense and tough, with high adhesive strength, high performance of acid and alkali resistance, anti-aging, anti-mildew, anticorrosion and waterproof. It is a safe Eco friendly solvent free product with high integration performance in the current exterior coating industry.
