               Current Field Testing

•   Worked with an ALC Paint Facility to develop a
    rotodome masking cover for painting and de-painting
•   Current process takes 6 personnel approximately 12
    hours to complete
•   Hopeful estimate is to reduce this time by 3-6 hours,
    and possibly reduce number of personnel required
•   Manufacturing glitch caused cover to be incorrectly
    fabricated. This is being rectified by the manufacturer
•   Further testing will continue when cover is received
    from manufacturer
•   This method may prove beneficial in other areas, i.e.,
    flight controls

               Current Field Testing

•   Providing support along with AFCPCO to an ALC
    engineering office field testing X-IT Prekote
•   Several different airframes (C-130 and A-10) are being
•   Aircraft are being visually inspected along with gloss
    and color readings being taken
•   Results are favorable, with X-IT performing as well or
    better than current conversion coating for adhesion
• Several SPOs have approved it for fleet-wide use

                    Laboratory Projects

•   Working with the B-52 SPO to resolve coating failures
    on radomes
•   Fleet-wide problem identified in 1997 CPAB
•   White elastomeric coating present that has not cured,
    and topcoat is cracking severely
•   Coating Stack-up:
    –   Anti-static coating, BMS 10-21 Type II applied per BAC 5837, no DFT
    –   Epoxy primer, MIL-P-23377 to a DFT of 0.6 mils (no type or class)
    –   MIL-C-83445A Polyurethane, Non-yellowing, White, Rain Erosion
        Resistant, Thermally Reflective coating with a DFT of 12 –14 mils
    –   MIL-C-83286 Polyurethane topcoat to DFT 1.5 mils per T.O. -23

                Laboratory Projects

•   Many of these specifications have been
•   Investigating whether it will be possible to eliminate
    the chromated primer and replace with non-chromated
    epoxy tie-coat per T.O. 1-1-8
• Replace white coating with currently used rain-erosion
    coating as a drop in replacement
•   Another avenue being explored is to replace entire
    coating system with an appliqué film. Manufactured
    by 3M to conform to contour of radome.
•   Close out 97-04 CPAB item
