The ASTM D5402 standard specifies a technique for evaluating solvent resistance of organic coatings by solvent wiping. This technique is suitable for evaluating the ability to chemically change during coating curing, particularly for curing coatings such as epoxy resins, vinyl esters, polyesters, alcoholates, and aminoformic acids. Determine when a coating reaches a specific solvent resistance level by performing a friction test using an appropriate solvent-impregnated cloth. However, reaching a solvent resistance level does not mean that the coating has been completely cured, so it must be ensured that the desired chemical and physical properties are achieved before painting finished coating or before use. This standard does not specify specific solvent types, friction times or expected test results, as these factors depend on the type of coating and the specific application context.
