Chemical Resistance Testing is utilized for evaluating the resistance of coatings or plastics to various test fluids. ATS’ automotive testing lab has extensive experience with chemical resistance testing. One of the most important evaluation methods for coatings and plastics is simply determining if they will be able to withstand the environment they may encounter during service. Chemical resistance testing is a convenient and efficient way of assessing the ability of a protective coating to resist degradation by chemicals before they are placed in service.
What are the Benefits of Chemical Resistance Testing?
Chemical resistance testing is carried out by immersing samples in various test fluids. The type of chemical reagents to be used are specified in applicable standards to reflect the intended service conditions. Plastics and organic coatings are susceptible to crazing or cracking following exposure to certain reagents. It is therefore very important to assess their behavior so that the proper polymer or coating type can be selected to avoid failures in service. Typical reagents include; Lubricants, transmission oil, brake fluid, engine coolant, battery acid, diesel fuel, beverages containing sugar and caffeine, window cleaners, sunscreens, household cleaners.
Common test methods used are ASTM D543, ASTM D1308, Ford MA-0015, Volvo STD 1026.8177, Toyota PPS 1002 and BMW GS 95003-5, although other customized tests can also be conducted based on intended or possible service conditions. The type of reagents, liquid concentrations, immersion duration, test temperature, and properties of the product evaluated after the exposure should be determined to reflect the anticipated service conditions. Typical properties of interest include, change in color, loss of gloss or adhesion, blistering, hardening or softening, swelling for coatings, and discoloration, softening or embrittlement for plastic materials.
