Independent certified laboratory has carried out tests and confirmed nine coatings systems from the aerospace business of PPG Industries, which also has included clearcoat or basecoat systems with no chromate.
These coatings systems meet the demands of Aerospace Material Specification 3095A from SAE International for the application of airline exterior paint. As SAE is reviewing the results, PPG Aerospace systems will be added to the qualified products listing.
Scott Cavin, Global Coatings Marketing Manager of PPG Aerospace for airlines and aftermarket stated that the AMS 3095A certification standard is considered to be significant for airlines, while an exterior coating system is selected.
Cavin added that the performance of the company’s coating systems is confirmed by the test results. Qualified standards will provide the required flexibility, particularly mixed fleets, to the airlines and third-party maintenance operators, while the best systems for use in applications are chosen.
PPG’s chromate-free systems have achieved the AMS 3095A standard as applied over DESOPRIME CF/CA 7502E primer and DesoGel EAP-9 pretreatment, including Desothane HS/CA 8000 series topcoat, Desothane HS/CA 8800 series topcoat, DESOTHANE HD/CA 9008 clearcoat or basecoat, Desothane HD/CA 9005 clearcoat together with Desothane HD/CA 9000 series basecoat.
Cavin stated that testing for standard has demonstrated a synergistic effect between the primer and pretreatment containing no chromate, offering significant protection and adhesion for the substrates.
Two coating systems from PPG have cleared AMS 3095A standard testing together with chromate-free PAC33CF primer and P99 wash primer, with the help of PPG topcoats.
