Paint and Coatings

 SWD959 Series SH126 One component moisture cure

   polyurethane (rigid) system industry storage tank/tower equipment internal wall special anticorrosion coating

Descriptions                 Tanks and towers are main equipment in the industrial plant, in general, they need long-term anticorrosion life. The internal wall is very easy to be corrosion damaged since it stays in a variety of chemical media environment in certain temperature for a long time. Developed by SWD Urethane Co., USA, the storage tank tower equipment internal special anticorrosion coating has excellent adhesive strength and mechanical performance with metal substrate, high anticorrosion performance on various media, providing a good protection for the long-term application of tank and tower equipment.

Characteristics              The high performance polyurea polyurethane prepolymer resign in the coating has excellent inherent anticorrosion properties of acid resistance, alkali resistance, salt resistance, oil resistance, water resistance and many chemical media resistance. Coating is smooth, tough, with high adhesive strength, temperature variation. It is one component environment friendly product，certificated as "Green Star “ material which has no benzene solvent, no catalyst and no construction performance pollution.
