Conductive Repair Coatings

The central technical objective of the proposed project is development of a Conductive Repair Coatings which can be applied to multiple aircraft substrates and meet specific electrical conductance throughout the life of the coating. We propose for Phase Ito develop a conductive repair coating (CRC) having improved conductivity level and consistency in conductivity over previous systems. The system based on either one or two component chemistry will cure to achieve a time-to-fly of <4 hours. Resistance toenvironmental degradation of electrical conductance, adhesion, and elongation (embrittlement) will be extended over reference. Its also the objective that this coating system will both maintain and enhance the physical and mechanical properties of thecoating film compared to previous conductive systems and not deter from the coatings basic properties such as: flow, viscosity, dry-time, gloss, visual color, and potlife. The focus of the present proposal is a specially developed polymer matrix whichcontains modified fillers for new aircraft technology and based on novel polyurethane and or polyurea chemistry and have a conductance of <20 ohms/square. This experimental coating system can have great potential in many commercial applications. Thespecific uses include but are not limited to: anti-static coating for both military and commercial aircraft with respect to lighting strikes, conductive floor coatings for hospital surgery and
