Abstract

The invention relates to a powder coating, and in particular relates to a high-adhesion powder coating which comprises the following components in parts by weight: 560-620 parts of outdoor polyester resin, 42-45 parts of a curing agent TGIC, 8-10 parts of a universal leveling agent, 3 parts of benzoin, 5-10 parts of a curing accelerant, 3-5 parts of micro powder wax, 5-10 parts of a dispersing agent aid, 20-50 parts of epoxy resin, 5-250 parts of pigment and 80-350 parts of packing. The power coating provided by the invention is simple in formula, low in production cost, high in adhesion and relatively high in scraping resistance.

Description

technical field [0001] The invention relates to a powder coating, in particular to a high adhesion powder coating. Background technique [0002] General powder coatings are a compromise of various properties. For some applications that require punching after the coating film is baked and formed, the adhesion of the coating film cannot meet the requirements, which often leads to cracking of the coating at the edge of the hole after punching. , and even peeling of the coating. Contents of the invention [0003] In view of the above defects, the object of the present invention is to provide a kind of high adhesion powder coating with simple process formula, strong coating adhesion and relatively scratch resistance. [0004] The technical scheme that the present invention adopts for this reason is: [0005] A kind of high adhesion powder coating, it is made up of following components, and the parts by weight of each component are: [0006] Outdoor polyester resin 560-620 pa...
