  
One 4" by 4" plate from each sample is used to evaluate coating resistance to moisture permeation. Tap water maintained at 150 degree Fahrenheit for 24 hours is the solution. Certain specifications require higher temperatures and/or durations. After the test cycle, a 1" by 1.5" rectangle is scribed through the coating. Evaluation is performed by testing the adhesion of the coating to the substrate. The procedure used is the same as with the cathodic disbondment test. |
