色漆和清漆 杯突试验
Application Summary AI generated
This standard specifies the cupping test method for evaluating the adhesion, elasticity, and resistance to cracking of paint and varnish coatings on metal substrates when subjected to slow, controlled deformation. It is primarily applied in the coatings industry for quality control and performance testing of paints on sheet metal, such as automotive body panels, household appliances, and metal packaging. The test simulates the mechanical stress coatings endure during forming processes like stamping or bending.
