Description:

The Phase I objective is to combine pretreatment, primer, and topcoat into a one-component, single-layered, water-based aircraft coating to replace the currently used three-layered coating. Most importantly, the new coatings will be safe for the environment and aircraft painting workers. Furthermore, it will reduce costs. After intensive review, ALTEC USA will select corrosion-inhibiting pigment, pigments and extenders, aqueous polymer dispersions, and additives. Corrosion-inhibiting pigment choices include calcium molybdate, modified zinc phosphate, calcium salt, or carboxylic acid with free carboxyl groups. Recently developed aqueous polymer dispersions, as typified by hybrid, IPN, polyblend urethane/acrylics are the choice resin systems. Selection of corrosion-inhibiting compositions and aqueous dispersions will be made by the statistically designed experiments. ALTEC USA plans to make eight aircraft coatings using two selected corrosion-inhibiting compositions and four aqueous polymer dispersions. Coatings will be tested for corrosion resistance, adhesion, cold temperature flexibility, cleanability, fluid resistance, and durability to demonstrate that the coatings are equal, if not better than the current system.

The results of this effort will be most useful to aerospace companies and the U.S. Department of Defense (DoD), specifically the U.S. Navy and U.S. Air Force. The Air Force and the Navy use aircraft coatings for their fleets. Implementation of ALTEC USA's clean one-component, single-layered aircraft coating, in lieu of the three-layered coating, should reduce costs and mitigate environmental and toxicity problems relative to currently used aircraft coatings. Other federal agencies such as the National Aeronautics and Space Administration (NASA) also will benefit. The final report containing the new design will be made available to encourage federal agencies to use the results.
