ASTM D7835/D7835M-23 《Standard Test Method for Determining the Solvent Resistance of an Organic Coating Using a Mechanical Rubbing Machine》 Related products

The ASTM D7835/D7835M-23 standard specifies a method for determining the solvent resistance of organic coatings using a mechanical friction machine. It is suitable for organic coatings that undergo chemical and/or physical changes during curing. This method evaluates the solvent resistance performance of coatings by applying solvent friction on the coating surface by a mechanical friction machine. The test results can be used for quality control in the laboratory, field or manufacturing shop. The standard does not specify the type of solvent, the number of frictions or the expected results. These should be determined by consultation between the manufacturer and the user. This method can help evaluate the chemical bonding and physical performance of coatings under different curing conditions, providing a basis for formulation optimization and application of coatings.
