The nylon powder coating for car part is made of high-performance nylon through special physical processes. The powder is a regular spherical shape with good dry powder flowability, suitable for fluidized bed coating technology; The friction coefficient between the coating formed by processing this nylon powder and the metal is small, and the wear resistance is excellent. The adhesion with the metal is excellent, and the special primer 7P-0200 can make the adhesion between the nylon coating and the metal more excellent; The coating has good flexibility, can bend freely without breaking, is wear-resistant and scratch resistant, and is an excellent metal component protection material that can meet the high-end requirements of metal components in the automotive field.
