GB/T 23989-2009 "Determination of Resistance of Coatings to Solvent Rubbing" specifies the test method for determining the resistance of coating films to solvent rubbing, and is applicable to the testing of various coating products. During the test, degreased cotton or gauze soaked with a specified solvent is used to rub back and forth on the surface of the coating film, and the number of rubs at which the coating film shows damage is recorded. The test requires tools such as an abrasion tester (or manual rubbing device), degreased cotton, solvent, and a stopwatch, providing a standardized method for evaluating the solvent resistance of coating films.
