Thermal application techniques for applying protective coatings have been popular as an alternative application method to traditional solvent-borne coatings having a high VOC content. The performance in a marine environment of thermally applied coatings is being evaluated and compared to traditional solvent-borne systems. Thermally applied organic coated specimens have been prepared using two of the three most popular thermal application methods. In addition to traditional accelerated laboratory test methods, coated test specimens have been atmospherically exposed in a marine environment at the Ocean City Research test facility. Four programs involving the performance of thermally applied organic coatings are used as a database for performance comparisons in this paper. While thermally applied coatings offer unique production attributes, no specific corrosion protection advantages of thermally applied coatings have been identified.
