GB/T 23989-2009 standard specifies the test method for determining the solvent wiping resistance of Paints, varnish or related products. This standard applies to coatings that undergo chemical reactions during curing, such as epoxy resins, alkyd resins, polyurethane Resin Coatings, etc. The test methods are divided into manual wiping method (A method) and instrument wiping method (B method), respectively, to evaluate the durability of the coating surface under the action of solvents. Wipe with solvent-soaked absorbentcottonph or Miscellaneous material to evaluate the solvent resistance of the coating performance. This standard refers to GB/T 3186, GB/T 9271, GB/T 13452 and other relevant standards to ensure the conformity and Reliability of the test. The implementation of this standard helps to evaluate the durability and performance of coatings in actual use, providing an important quality control basis for the Coatings industry.
