Powder spraying equipment

The curing agents for epoxy powder anticorrosive steel pipe mainly include diamine, diamine derivative, anhydride, imidazole, cyclic ether, phenolic resin, polyester resin and amine complex.

The characteristics of epoxy powder coatings are as follows:

① Epoxy powder coating has strong adhesion, especially to metal;

② Epoxy powder coating has good mechanical properties, high hardness, scratch resistance and corrosion resistance;

③ The epoxy powder coating has low melt viscosity, good leveling property and no shrinkage and other defects;

④ There are many kinds of epoxy powder coatings, such as matte, glossy, pattern, hammer pattern, etc;

⑤ The coating thickness of epoxy powder coating can reach 50-300 μ m at one time, and the uncoated powder can be recycled;

⑥ The coating equipment of epoxy powder coating is highly required, which needs complex and precise equipment.

Strong adhesion, good adhesion between paint film and paint film. Excellent antirust and water-resistant performance, using excellent antirust raw materials, can ensure its antirust performance. It has good mechanical strength, tough film, wear resistance and impact resistance. High solid content and thick film. The film was cured at room temperature.
