Chrome-Free, Zero VOC Coating for Aircraft Radar

The objective of the program is to demonstrate through resin synthesis and system formulation a single-coat, chromate-free, low or zero volatile organic compound (ZVOC) conformal coating that meets the performance requirements for radar antenna systems.Luna Innovations, Inc. will synthesis novel autoxidative water-based polyurethane dispersions that will facilitate formulation of an air-cured single-component, ZVOC primer. Incorporation of low-cost, environmentally acceptable plant-based extracts thatexhibit remarkable corrosion inhibition into the coating system will provide enhanced corrosion protection to facilitate elimination of the primer thus achieving the desired single coat system. Luna will demonstrate the required performance properties ofthe coating system through the appropriate standardized military tests and in direct comparison to existing military specified products. Particular emphasis will be given to the dielectric properties and corrosion performance of the coating. Substantialcost 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.
