This standard tests the resistance to embossing and blocking of organic coatings on metal substrates. The test cuts the coated metal sample into several pieces and heats it at a specified pressure and temperature for a period of time. After chilling down, the sample is checked for signs of adhesion or indentation. This method is suitable for evaluating the performance of coatings during the manufacturing process to ensure that they meet the requirements for use. This standard provides procedures for determining the embossing and blocking resistance of coatings, ensuring the Reliability and Durability of coatings in practical applications.
