Characteristics: Phosphating film and the overall structure of the steel pipe is a tight, with a porous, sealants, coatings and so on can infiltrate into the pores, closely combine with phosphating film, phosphating film with porous coating, uniform is careful, the paint into the pore, increased greatly and improve the coating adhesion and gloss saturation.
Application: It is widely used in construction machinery, shipbuilding, precision machinery, hydraulic system and other industries. The surface of phosphating precision seamless steel pipe is especially suitable for spray painting or plastic spraying treatment. The paint surface has strong adhesion, excellent and beautiful effect, and the anti-rust effect is greatly strengthened.
