    1. USAF Selective Topcoat Removal System Air Force Corrosion Program Conference Richard I Slife WR-ALC/MAPE 13 March 2003

    2. Overview What is it? What can it do? What has been done with it? Where do we go from here?

    3. Barrier Coating/Selective Paint Stripping Concept

    4. What Can It Do? Encapsulation of chromated primer No leaching of chromates through the barrier coating was detected in water after stripping Topcoat removal rates of up to 4 ft2/min using 8,000 psi water Improvements in the weathering of the topcoat

    6. MIL-PRF-23377/APC

    7. C-141 Aft Cowl Skins

    8. What has been done? Laboratory qualification testing F-15 (T/N-0078) parts, March 2000, ANG Jacksonville, FL C-130 (T/N-0991) parts, September 2000, AFSOC Eglin AFB, FL F-15 (T/N-6019) full-up, October 2001, ANG Jacksonville, FL

    9. Where do we go from here? Define needs based on weatherability improvements or strippability Resolve issues related to AF patent and material procurement Obtain “buy in” from additional weapon system SPO’s Investigate other primer-topcoat combinations Conduct NDI and multiple strip/repaint investigations Expand process prototyping ESTCP FY04 proposal CBA
