GB_T 9279-2007 "Scratch Test for Paints and Varnishes" was proposed by the China Petroleum and Chemical Industry Association and is used to determine the resistance of coatings of paints, varnishes and other related products to scratch penetration by hemispherical needles under standard conditions. Test method. For composite coating systems, the scratching needle can penetrate to the substrate or to the intermediate coating. This standard method is mainly used in two aspects: 1) As a "pass/fail" test, that is, during scratching Test by applying a specified load to the needle to evaluate whether the coating meets specific requirements; 2) Determine the minimum load required to penetrate the coating by applying a gradually increasing load to the needle.
