Coating and packaging materials testing

Coating is an organic chemical polymer material that can be coated on the surface of an object with different construction techniques to form a solid polymer compound film with firm adhesion, certain strength, and continuous. It is usually composed of base materials (resins, adhesives), pigments, fillers, solvents, and a small amount of functional additives.
         Coatings generally have the functions of protection, decoration, marking, antifouling, insulation, etc., and are widely used. Therefore, coating testing is known as one of the most effective ways for the majority of coating production and use companies or individuals to verify the quality of coatings. With the development of the national economy and the progress of science and technology, coating inspection is gradually advancing the development of the coating industry to water-based, high-performance, high-end, and functional, and the prospects are more broad.
