Depending on the type of coating used, there are different designations, such as the primer layer being called the primer layer, and the topcoat layer being called the topcoat layer. Generally, the coating obtained from coatings is relatively thin, ranging from about 20 to 50 microns, while thick paste coatings can obtain coatings with a thickness of more than 1 mm at a time. It is a thin plastic layer applied to metal, fabric, plastic, and other substrates for protection, insulation, decoration, and other purposes.
