Epoxy powder coating is a kind of thermosetting powder coating with corrosion resistance and toughness, which is the earliest and rapid development. It is composed of epoxy resin, pigment filler, additive and curing agent.

The powder coating is a kind of coating which contains 100% solid and powder form. It uses air as dispersion medium. Epoxy powder coating is a kind of thermosetting powder coating with corrosion resistance and toughness, which is the earliest and rapid development. It is composed of epoxy resin, pigment filler, additive and curing agent. The preparation of epoxy powder coatings is the only way to produce thermosetting powder coatings, i.e., melt mixing extrusion method, mixing, melt mixing extrusion, fine crushing.

Epoxy resin epoxy powder coating: epoxy equivalent should be solid resin 700-100 between, the molecular weight distribution was narrow; in the curing temperature, low melt viscosity, easy levelling, coated flat and thin; of pigments and fillers dispersed well.

The curing of epoxy powder coating is the main agent of dicyandiamide, dicyandiamide derivatives, acid anhydride, imidazole, cyclic ethers, phenolic resin, polyester resin, trifluoride boron amine complexes. The industry, generally uses dicyandiamide, imidazole and cyclic ether.
