PPG AerospacePRC-DeSoto, the aerospace coatings and sealants
business of PPG Industries, is marketing new primers that significantly
reduce time in the paint shop. In one case, the company says that
Raytheon Aircraft, by switching to PPG's Desoprime HS7755BE polyurethane
primer, has been able to eliminate the need to sand its primer
coats to obtain a smooth finish, cutting application cycle times
by half. At Bombardier, PPG's Desoprime HS CA7700 epoxy primer,
which dries three times faster than PPG's first-generation primers
and is simpler to apply, is now being used for the CRJ regional
jets.
