As the first physical defense against exposure to foreign substances, coatings are required to be able to withstand the environment its substrates are made for. In addition, they often get exposed to chemicals and acids from cleaning products, spills, or fumes as well, making it crucial that the outmost layer of the coating similarly has the ability to resist certain acidic or alkali chemicals. ASTM 1308 determines the effects of household chemicals on clear and pigmented organic coatings, be it discoloration, change in gloss, blistering, softening, swelling, or loss of adhesion.
