Abstract : The goal of this three year DARPA project is the identification, preparation and application of chromate-free alumoxane-based durable coatings that provide a high level of corrosion resistance with low VOC and HAP emissions. The coating system is being designed for repair and maintenance of corrosion/mission coatings on existing DoD aircraft inventories. In the third quarter of the first year of this ARPA project, we have continued the syntheses of alumoxane-epoxy, alumoxane-urethane and phosphonato-alumoxane precursors that can be used to prepare durable alumoxane based coatings. In this quarters work we have also begun to evaluate alumoxane-epoxy and alumoxane-urethane resins as coatings on aluminum substrates. In addition, cerium/molybdenum exchanged alumoxanes were prepared as precursors for the preparation of corrosion resistant oxide barrier coatings.
