The GB/T 9280-2008 standard specifies the method of stackability testing for Paints and varnishes within a specified drying time. This test evaluates the damage resistance performance of coatings by simulating the pressure of stacking of painted objects under standard environment conditions. The test uses a specific instrument and load to apply pressure to the test piece and check the damage of the coating after a specified time, such as imprinting, blocking or peeling. The standard aims to ensure the Reliability of coatings in practical use, especially the damage resistance of intermediate coatings during handling and storage.
