Waterborne Polymeric Films.
Abstract
Air Force Materials Laboratory contract proposed the development of a high-performance water-based polymer system to function as a pigment binding vehicle for military aircraft coatings. Screening studies on numerous commercially available aqueous resin systems enabled a ranking based on clear-film performance. A few resins were identified as displaying performance approaching the established criteria. Aqueous polyurethanes, aqueous acrylic solution polymers, and epoxy emulsions exhibited near acceptable fluid resistance and flexibility. One member of the class of water-reducible alkyds exceeded the performance of other resins in this class. The selected resins were subjected to pigmentation studies. Primer formulations using strontium chromate pigment were prepared and evaluated. Topcoat formulations with rutile titanium dioxide were also prepared and evaluated. Results of clear and pigmented film studies indicate that the class of aqueous polyurethane dispersions would be most likely to meet the required fluid resistance and flexibility. Aqueous acrylic solution polymers successfully resisted the test fluids but flexibility was lacking.
