Description

technical field [0001] The invention relates to an epoxy resin zinc-rich heavy-duty anti-corrosion powder coating, which belongs to the technical field of powder coatings. Background technique [0002] Heavy-duty anti-corrosion coating is a kind of coating that can be used effectively for a long time under severe corrosive environment. The surface treatment and coating construction and maintenance requirements are also very strict. This type of paint used to be liquid paint, and usually requires multiple coats to meet the requirements. [0003] Powder coating is a solvent-free, 100% solids powder coating. It has the characteristics of no solvent, no pollution, recyclable, environmental protection, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. In recent years, due to its safety, high efficiency, and pollution-free characteristics, powder coatings account for an increasing proportion in the field of heavy-duty anti-c...
