Protective coatings for military equipment must resist contamination by chemical warfare agents. In Phase I, TDA Research, Inc. (TDA) and the dendrimer research team at the University of South Florida (USF) prepared and tested materials that can greatly improve the performance of chemical agent resistant coatings now used by the U.S. Army. Two classes of materials were incorporated into coatings similar -to those currently in use, and showed the ability to deactivate a simulant for a chemical agent, and, in tests by the U.S. Army, to deactivate sulfur mustard (agent HD). The modified coatings could be applied by spraying, were unaffected by the standard decontamination agent DS-2, and had the potential to decrease the emission of volatile organic compounds (VOCs) during application. An engineering analysis showed that the new materials could be produced at competitive prices. Phase II R&D will consist of five tasks: materials synthesis, preparation and evaluation of coatings, engineering analysis, development of methods for larger scale synthesis, and a field test of dendrimer-modified coatings. To facilitate commercialization, TDA will work with a major producer of coating materials. In Phase III TDA would first negotiate with this company to license the technology for both military and commercial markets. The proposed system can be used by the military to improve the performance of chemical agent resistant coatings. The methods and materials being deyeloped can be used by the coatings industry to improve the protective properties of the coatings and lower VOC emissions during the coating process.
