Test Methods

Chemical Resistance

Chemical resistance tests are used to evaluate the resistance of coatings to various concentrations of reagents or suspected soil contaminants.

The test is carried out by immersing or spot testing samples in the test reagents as required by the selected standard and is intended for evaluating the effect of various chemicals on coatings, resulting in any objectionable alteration in the surface, such as discoloration, change in gloss, blistering, softening, swelling, loss of adhesion or special phenomena.
