Elbow elbow lined when more types of corrosive media, such as acid, alkali, salt, oxidants and water vapor, etc., the coating must be chemically inert, acid salt corrosion, the coating should be compact structure, water permeability good, strong adhesion, tough fullness. Such applies IPN8710 corrosion. , IPN8710 anticorrosion primer: from polyurethane, polyethylene, modified epoxy resin, non-toxic anti-rust pigments, additives and other components, room temperature curing form an interpenetrating network, a dense film structure, acid and alkali, salt, anti- rust excellent performance, strong adhesion for water supply pipeline wall corrosion primer coating. IPN8710 anticorrosive finish: epoxy, rubber resin-modified, non-toxic anti-rust pigments, additives and other components. Excellent chemical resistance, non-toxic, anti-microbial erosion, corrosion for water supply pipeline wall finish. FBE epoxy powder preservative FBE epoxy powder preservative structure: electrostatic spraying epoxy powder coating the surface of the elbow, one film. The coating has a coating operation is simple, clean, good coating impact resistance and flexural properties, temperature resistance advantages. 2PE / 3PE preservative 2PE / 3PE antisepsis structure: the elbow surface electrostatic spraying epoxy powder and lateral wound adhesive, lateral wound polyethylene coating, with three excellent performance, thereby significantly improving the overall corrosion pipeline quality. Resistant to chemical corrosion, cathodic stripping, resistance to mechanical damage performance. Coal tar epoxy coal tar epoxy
