1. Strong adhesion of epoxy powder coating, especially for metal;
2. Paint film mechanical performance is good, high hardness, scratch resistance, corrosion resistance;
3. low melt viscosity, good flowing property, basic no pinhole coating and shrinkage cavity defects;
4. many design and color, epoxy powder coating can be made without light, light, decorative pattern, hammer, etc.
5. a coating thickness of the coating epoxy powder coating can be up to 50-300 microns, for not coated powder, can be recycled again;
6. Epoxy powder paint coating equipment requirement is high, the investment is big, need complex and sophisticated equipment.
