3rd Floor, No. 38, Lane 1688, Lianhang Rd., Minhang District, Shanghai, China (Mainland)
Petrochemical Industry is a hard-hit area suffering corrosion problems, almost all the metal and concrete structures need anticorrosion treatment, and heavy duty anticorrosion is required for some parts. In association with key scientific institute, SWD US Co. Developed SWD9512 Heavy Duty Anticorrosion Polyurethane Protective Coating, based on common polyurethane coating, this product has been applied in American area, with ideal performance of anticorrosion.
The product has high reactivity, fast curing time, could spray-applied forming on curved,slope and vertical surface without sagging. Insensitive to moisture and temperature,temperature variation resistant. Dense and flexible coating will be firmly adhesive to substrates like metal and concrete. High performance of resistance to acid, alkali, salt, sulfide. No bubbles and peeling when long term immersion in liquid. Weather resistant, no powdering and cracking when enduring the impact of cold and hot weather.
