Current DOD chemical agent resistant coating (CARC) topcoats are required to provide protection to the substrate from the harsh natural/service-imposed operational environments. Current coating systems are solvent-borne two components that require accurate metering of the components. PolyComp Technologies proposes to develop novel one component, zero VOC, ambient curing CARC topcoats that can be applied by conventional methods. Based on polyurethane building blocks, the coating will develop novel morphology upon cure, creating a water impermeable surface that is stable towards CB decontamination fluids, as well as satisfying the requirements as drop-in replacement for current polyurethane coatings Benefits The novel coating system can be used as dorp-in replacements for current topcoats in USMC as well as assets in other Services. The coating can also be used in commercial chemical resistant applications such as chemical plants, and protection for Homeland Defense equipments Keywords CARC, polyurethane, coatings, ambient cure, surface energy
