Characteristics
SWD900 is a 100% solid content aromatic polyurea elastomer. It has excellent waterproof anticorrosion and abrasion resistance property which has been widely applied in the industrial and commercial filed for the anticorrosion waterproof protection.
Coating appearance shows smooth, dense and tough. With high adhesive strength, excellent tensile strength, tear strength, impact strength and wear resistance, it can bear the heavy impaction and high flow brush of liquid, with stable chemical resistance, anti normal corrosion media, such as acid, alkali, salt, seawater, etc. no blister, no peel off after long period sinks in corrosion solvent.
