The objective of the program was to develop decontaminating systems for persistent chemical agents using micronized carbon. These systems must be effective in absorbing chemical agents and designed to the following goals 1 Act rapidly over a wide temperature range, 2 Be non-toxic and remain stable, 3 Not damage material and equipment on contact, and 4 Be easily and rapidly applied to vehicular equipment, clothing and ancillary equipment. The method of study was to select key ingredients, i.e., activated carbons, thixotropic agents, dispersants, pigments and solventantifreeze and formulate a system containing a minimum of 25 active carbon. It should be easily applied by spraying to a coverage of 4 mgsq cm and remain stable not settle during static storage of at least two years. Key methods of investigation included evaluation of mixing techniques, effects of various thixotropes and dispersant on viscosities and stability and the evaluation of spray equipment for optimization of techniques as well as equipment. In addition, studies were conducted whereby dry formulation of the same key ingredients were formulated using high shear dry mixers. These compounds were tested for uniformity, adhesion to woven surfaces and effective coverages in the 4 mgsq cm range.
