▎ 摘  要

NOVELTY - Powder coating comprises modified polyester resin, modified filler, curing agent, pigment, material A and auxiliary agent. The material A includes defoaming agent, benzoin, leveling agent and brightening agent, or sanding agent. USE - The powder coating is useful in spraying magnesium alloy (claimed). ADVANTAGE - The powder coating has better adhesive force and adhesive strength after forming film on the surface of the magnesium alloy, and has good anti-corrosion effect, can effectively solve the problem of bubble generated by surface spraying of magnesium alloy product, shrinkage hole and bad adhesive force. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of powder coating, comprising mixing, stirring, extruding, pulverizing, and sieving the powder coating raw materials.
