Abstract

Current chemical and corrosion resistant primers for land and amphibious military vehicles are two component solvent or waterborne epoxy coatings. Unfortunately, problems with component mixing and concentration errors with these multi-component paints often compromise coating performance in the field. Therefore, TDA Research, Inc. (TDA) proposes to develop a zero volatile organic compound, waterborne, single component, chemical agent resistant (1K Z-VOC) primer that will eliminate the need for mixing to ensure consistent coating performance and have no impact on air quality. In Phase I TDA will develop the resin system, which achieves satisfactory viscosity for application by spray, brush or roller. We will make clear coats to demonstrate the curing chemistry and we will test film formation and coating performance. In Phase II we complete development and testing of the coating, including field test and long-term durability studies. Single-component coatings offer simple application and reliable performance. They offer ease of use and eliminate the problem of mixing errors during application that can compromise performance in the field. Additionally, as environmental standards for VOC emissions on coating become increasing more stringent, zero-VOC systems become more desirable. The single-component zero-VOC epoxy system we propose to develop will be used not only by the U.S. military, but will also find wide use in architectural, industrial maintenance and transportation coatings where high chemical and weathering resistance is required, and where application with standard equipment and ambient curing is desired.
