PPG Industries’ aerospace business has qualified nine coatings systems to SAE International’s Aerospace Material Specification 3095A for airline exterior paint.

According to Scott Cavin, PPG Aerospace global coatings marketing manager for airlines and aftermarket, having systems on the AMS 3095A Qualified Products Listing simplifies paint selection for airlines and third-party maintenance operators.
“Coatings in a qualified system have undergone independent testing that shows they work together to provide optimum performance across aircraft platforms,” Cavin said. “Airlines can use PPG’s qualified systems across their fleets to achieve the application and performance benefits the testing has proven.” Cavin added that PPG chromate-free systems offer exceptional corrosion resistance; PPG basecoat/clearcoat systems demonstrate improved color and gloss retention with reduced weight and application time; and DESOTHANE(R) HS/CA 8800 and 8000 series topcoat systems continue to offer excellent gloss and durability with flexible cure times to meet production requirements.

Added to the AMS 3095A Qualified Products Listing are four PPG chromate-free systems applied over DesoGel EAP-9 pretreatment and DESOPRIME(R) CF/CA 7502E primer by PPG Aerospace:

Desothane HD/CA 9000 series basecoat with Desothane HD/CA 9005/B900 clearcoat
Desothane HS/CA 8000 series topcoat with Desothane HD/CA 9005/B900 clearcoat
Desothane HS/CA 8800 series topcoat
Desothane HS/CA 8000 series topcoat

Three of the approved coatings systems on the AMS 3095A Qualified Products Listing use Desoprime CF/CA 7502E primer by PPG Aerospace with a widely available conventional conversion coating:

Desothane HD/CA 9000 series basecoat with Desothane HD/CA 9005/B900 clearcoat
Desothane HS/CA 8800 series topcoat
Desothane HS/CA 8000 series topcoat
Two PPG coatings systems on the AMS 3095A Qualified Products Listing use P99 wash primer and chromate-free PAC33CF primer:
Desothane HS/CA 8000 series topcoat
Desothane HS/CA 8800 series topcoat

Cavin said independent laboratory testing has been completed on one additional PPG chromate-free basecoat/clearcoat system that confirms adherence to AMS 3095A requirements and is being reviewed by SAE.
