Chromate-Free, Room-Temperature Cure Fuel Tank Coating

The objective of the program is to demonstrate through the use of novel corrosion inhibitors and coating formulation a chromate-free, room temperature curing, environmentally acceptable fuel tank coating that meets the performance requirements of SAE AMS-C-27725. Luna Innovations, Inc. will formulate and evaluate novel coating formulations specifically engineered to inhibit corrosion and microbial growth, resist environmental degradation while maintaining compatibility with existing aircraft materials and structures. Accelerated development of the new coating system will be achieved through the use of proven resin systems modified with corrosion inhibitors and other additives to produce a tack-free coating with excellent physical and barrier properties that remains suitable for spray applications. Excellent corrosion protection will be achieved with low-cost, environmentally acceptable inhibitors, including plant-based extracts and novel high-performance chrome-free pigments. Luna will demonstrate the performance properties of the coating system through the appropriate test methods and in direct comparison to a chromate-bearing military qualified product. Substantial cost and performance benefits with concomitant decreased environmental impact will be realized from the novel high performance system formulated to conform to existing logistical and operational requirements.
