Testing by an independent certified laboratory has confirmed nine coatings systems by PPG Industries’ aerospace business, including chromate-free basecoat/clearcoat systems, meet requirements of SAE International’s Aerospace Material Specification 3095A for airline exterior paint. The results are under SAE review to add the PPG Aerospace systems to the Qualified Products Listing.
According to Scott Cavin, PPG Aerospace global coatings marketing manager for airlines and aftermarket, the AMS 3095A standard is an important consideration for airlines when choosing exterior coating systems.
“These test results confirm performance by PPG coatings systems,” Cavin said. “Qualification to the standard will give airlines and third-party maintenance operators the flexibility they need, especially with mixed fleets, when selecting the best systems for their applications.”
These PPG chromate-free systems have passed AMS 3095A standard testing as applied over DesoGel EAP-9 pretreatment and DESOPRIME(R) CF/CA 7502E primer:
• DESOTHANE(R) HD/CA 9008 basecoat/clearcoat
• Desothane HD/CA 9000 series basecoat with Desothane HD/CA 9005 clearcoat
• Desothane HS/CA 8800 series topcoat
• Desothane HS/CA 8000 series topcoat
“Testing has shown a synergistic effect between the chromate-free pretreatment and primer that gives remarkable adhesion and protection for the substrates,” Cavin said. “When these PPG systems are listed as qualified to the standard, they will be the first to be completely chromate-free.”
Two PPG coatings systems have passed AMS 3095A standard testing with P99 wash primer and chromate-free PAC33CF primer, using these PPG topcoats:
• Desothane HS/CA 8000 series topcoat
• Desothane HS/CA 8800 series topcoat
Systems including Desoprime CF/CA 7502E primer along with a conventional conversion coating and these PPG coatings have passed testing:
• Desothane HD/CA 9000 series basecoat with Desothane HD/CA 9005 clearcoat
• Desothane HS/CA 8800 series topcoat
• Desothane HS/CA 8000 series topcoat
