Water-Based Ensemble Coating
Abstract
In this project, TDA successfully developed and demonstrated a safe and effective prophylactic coating to achieve very effective decontamination of porous substrates with a water wash. The coating is particularly effective against G-agents (virtually complete protection), and is also very effective against sulfur mustard, agent MD, reducing heavy (10 g/sq m) MD contamination by over 99.5% when rinsed with water. The coating does require considerable water to rinse and therefore may not be applicable for forward-deployed forces, but may be useful to maintain operations in, for example, a contaminated air base. The formulation is inexpensive, uses commercially available ingredients, and can be efficiently applied by a band-operated trigger sprayer. It is non-corrosive by DOT standards, and is a minimal-to-mild ocular irritant and a borderline dermal non-irritant/irritant. It is non-flammable and self-extinguishing. Once applied, the coating remains effective indefinitely, with no degradation in performance upon storage of coated items for at least five months. The present formulation does have some limitations. While it is colorless, it is not optically clear and therefore cannot be applied to visors, night vision goggles, etc. The coating would need to be reapplied after rinsing and may be somewhat tacky and less durable in very humid environments.
