It is a thin plastic layer applied on metal, fabric, plastic and other substrates for the purpose of protection, insulation, decoration, etc. The coating can be gaseous, liquid or solid. The type and state of the coating are usually determined by the substrate to be sprayed. After the metal parts are processed, a layer of anti-rust coating is usually applied on the outside to improve its anti-rust performance. Water-based epoxy wear-resistant anti-rust coating is one of them.
