The coating is made of special resin, pigment and filler, curing agent and other auxiliary agents, mixed in a certain proportion, and then prepared by hot extrusion molding, crushing and sieving and other processes. They are stable at room temperature, electrostatically sprayed or fluidized bed dip-coated, then heated, baked, melted and solidified to form a flat and bright permanent coating film for decorative and anti-corrosion purposes. Commonly used in: shelves, cabinets, workbenches, logistics storage and transportation equipment, etc.
