High-Solids and 100-Percent Solids Coatings: A State-of-the-Art Investigation

reportActive / Technical Report | Accession Number: ADA247557 | Open PDF

Abstract:

The Corps of Engineers has used solution vinyl paints for corrosion protection of hydraulic structures on inland waterways for many years. These coatings have an excellent service life, however liquid paint contains a high amount of solvents. Recently enacted volatile organic compound VOC air pollution regulations put severe restrictions on solvents in paints. The purpose of this research was to investigate generic high-solids and 100-percent solids coatings under laboratory conditions and identify coatings, based on their performance in the laboratory tests, as candidates for field testing. Tests were conducted on 24 coatings to provide data that could be used to write performance specifications for high-solids and 100-percent solids coatings. The most severe laboratory test was the salt water immersion test. Seven coating systems of varied generic types survived this test and the fresh water immersion test without blistering. Six of them are recommended for field testing. Eleven coating systems performed satisfactorily did not blister in the fresh water immersion test and are recommended for field testing. Film thickness was not a significant factor in determining coating performance in the immersion tests nor in the accelerated weathering tests. Coatings, High-solids coatings.
