   SWD952 Series SH123 One component moisture

 cure polyurethane (elastic) system static

    conductive anticorrosion protective coating

Descriptions               Since the ordinary static conductive coating with low anticorrosion performance it will produce pitting or serious holes after used for a period. Based on the technologies of traditional epoxy static conductive coating and two components polyurethane static conductive coating SWD Urethane Co., USA studied and developed the one component high performance polyurea polyurethane static conductive anticorrosion coating. This product perfectly coordinated the coating properties of static conductive and anticorrosion together, providing an excellent solution to the anticorrosion and safety performance of oil storage tanks. It works quite well after being widely used in the America.

Characteristics               The coating takes one component polyurea polyurethane resin as main material the film of coating is dense, tough, with excellent physical mechanism properties, high anticorrosion and temperature variation performance on various media, such as acid, alkali, salt, oil, water and solvent. The surface electrical resistance of the coating is between10⁵ to 10⁹ ohm, static conductive stable, with high penetrate resistance performance.
