SYLMAR, Calif., April 9, 2014 – PPG Industries’ (NYSE:PPG) aerospace business has qualified a new chromate-free wash primer coatings system to SAE International’s Aerospace Material Specification 3095 for airline exterior paint.
The PPG Aerospace system added to the AMS 3095 Qualified Products Listing has DESOTHANE(R) HS/CA 8800 buffable topcoat applied over new chromate-free DESOPRIME(R) CF/CA 7530 epoxy wash primer and new chromate-free, high-solids Desoprime CF/CA 7065 polyurethane primer.
PPG continues to develop new products with improved performance in eco-friendly formulations for AMS 3095 qualification that meet airline maintenance needs, according to Scott Cavin, PPG Aerospace global coatings marketing manager for airlines and aftermarket.
“PPG developed new Desoprime CF/CA 7530 chromate-free wash primer and new chromate-free Desoprime CF/CA 7065 polyurethane primer that not only have reduced VOC (volatile organic compound) levels but also work together to inhibit corrosion on aluminum airframe structures,” Cavin said. “Having complete systems with AMS 3095 qualification facilitates their selection and use by airline maintenance operations.”
A system using a Desothane topcoat, Desoprime CF/CA 7530 wash primer and Desoprime CF/CA 7065 primer has VOC levels more than 60 percent lower than a standard system, Cavin said. In addition, Desoprime CF/CA 7530 wash primer has good washability, and it is formulated for electrostatic application. Desoprime CF/CA 7065 primer has resistance to fingerprints.
Application trials of the new PPG Aerospace wash primer and polyurethane primer at a major aviation maintenance operation demonstrated application benefits, low odor, sandability and surface contamination resistance, Cavin said.
He said the PPG system qualified to AMS 3095 has undergone independent laboratory testing that confirms performance.
