The ASTM D7786-2013 (2019) standard specifies a test method for determining the adhesion of enamel coatings, which is mainly used to evaluate the adhesion strength of enamel coatings on different substrates. The test determines whether the coating can maintain good adhesion during use by cutting, scribing or impacting the enamel coating, and then disbonding the coating with an appropriate adhesive tape. The test results are graded to help manufacturers determine whether the coating mass meets the requirements. This method is widely used in the quality control of enamel products, especially in the household appliances, kitchen supplies and building materials industries, to ensure the durability of enamel coatings and the adhesion Stability in long-term use.
