SWD POLYURETHANE (SHANGHAI) CO., LTD

  SWD959 Series SH125 One component

     moisture cure polyurethane (rigid) system

          industry metal anticorrosion protective coating

Descriptions                Anticorrosion and protection projects take place in various fields of the modern industry and most applied two components coating. The two components coating requires on-site preparation performance which not only increase labor work but also easily influence the painting quality by the improper proportion. In addition, the film quality is much more serious depended on the operation environment conditions. SWD Urethane Co., USA developed one component industry metal anticorrosion protective coating which provides a new channel for the anticorrosion field. This product is easy to use with excellent anticorrosion performance. It has been widely used in many fields of the America, etc.

Characteristics            Applied with one component polyurea polyurethane resin prepolymer as main film forming material, curing by absorption and reaction with air moisture, the coating contains large amount of urea bond, urethane bond and hydrogen bond which makes it to be excellent in physical and stable chemical properties with high performances of acid resistance, alkali resistance, salt resistance, oil resistance and water resistance. The coating is smooth, full bright, dense and tough, with high adhesive strength, temperature variation. It can be painted on simple surface treatment substrates, easy to use, with wide demand for the performance environment.
