A coating is a solid continuous film obtained from a single application of paint, which is a thin plastic layer applied to metal, fabric, plastic, and other substrates for protection, insulation, decoration, and other purposes. Coatings can be gaseous, liquid, or solid, and the type and state of the coating are usually determined by the substrate to be sprayed. The scope of coating testing includes fireproof coatings, hydrophilic coatings, anti-corrosion coatings, metal coatings, etc. Coating testing items include aging testing, glossiness, quality testing, adhesion, resistivity, temperature resistance, etc. Coating Testing Standards 1.
