Environmentally Acceptable Conversion Coating for Un-Coated Aluminum Alloys

The objective will be to develop and evaluate an advanced, environmentally acceptable, anticorrosion coating that will be inexpensively applied to un-coated, marine-grade, aluminum alloys. We will develop and evaluate a single component, zero volatile organic compound (VOC's) coating which has performance suitable for the exterior surfaces of military land and amphibious equipment. UDC will demonstrate the feasibility of our approach to develop a coating system for un-coated, marine-grade, 5000 series aluminum alloys that will retard corrosion and staining while providing LSA properties. UDC will prove the feasibility of formulating coatings which demonstrate the appropriate mechanical, chemical, and rheological properties at a dry film thickness of about 0.6 to 0.9 mils. The coated substrates will be tested for bond strength, corrosion resistance, LSA and outdoor weathering. A final report with results and conclusions will be submitted at the end of Phase I program.
