Abstract
The effects of acidic deposition on painted metal substrates have been investigated using a series of accelerated laboratory exposure test methods. The study examined a commercially available alkyd paint/primer system applied to a low carbon (ASTM A569 CQ) steel substrate exposed under a variety of simulated acidic conditions to determine the micro/macro effects of such exposure. Surface analytical, electrochemical and mechanical test methods were used to characterize the performance/degradation modes of the painted metal coupons. The results of these exposures identified accelerated loss in mechanical properties and discoloration of the paint in the presence of SO2.
