Abstract:

The Civil Engineering Laboratory investigated various accelerated laboratory test procedures for use in predicting the long-term performance of paint systems for steel exposed to a marine atmosphere. Accelerated laboratory test procedures included determining the electrical properties of the paint systems on steel panels AC and DC resistance and AC capacitance, the water vapor permeability of free films of the paint systems, and the performance of the paint systems on steel panels exposed to a wet-and-dry-cycle test procedure. Results of the accelerated laboratory tests on 12 paint systems were correlated with their long-term performance in two different marine atmospheric environments using linear regression analysis.
