Description:
The paper discusses a field evaluation of the feasibility of using alternative low-volatile organic compound (VOC) coatings to replace higher-VOC coatings. he evaluation includes chemical, performance, and outdoor exposure testing. he feasibility of five alternative coatings for reducing pollution is considered. he coatings are compared to a standard coating that is being used in practice. lthough outdoor exposure testing is not yet complete, available results indicate that all of the coatings have characteristics that could make them viable alternatives. or VOC emissions reduction, coating 4 (a two-component polysiloxane epoxy) was the best. oatings 5 (a water-reducible alkyd/waterborne acrylic system) and 3 (a solventborne alkyd/waterborne acrylic system) were not far behind. oatings 2 (a waterborne epoxy/latex system), 4, and 5 had equivalent results for impact resistance testing at an 8.9 m-kg f allure point. or the adhesion test, coatings 1 (a three-coat polyurethane system), 4, and 5 were equivalent in results. oatings 1, 4, and 6 (the standard, a solventborne alkyd system) had equivalent results for the methyl ethyl ketone (MEK) rub test. oating 4 outperformed all the other coatings in the pencil hardness test. he overall best coating, before considering outdoor exposure testing, was coating 4.
