Chrome-Free PPG Aerospace Coating Qualified to SAE Standard
PPG’s CA7088 integral fuel tank aerospace coating has been qualified to SAE International’s Aerospace Material Specification AMS-C-27725, Type 3, Grade 2.
PPG’s CA7088 integral fuel tank aerospace coating has been qualified to SAE International’s Aerospace Material Specification AMS-C-27725, Type 3, Grade 2.
Formulated without chrome as an intentionally added ingredient, the coating is qualified to the specification for corrosion-preventative coatings as Type 3: a chrome-free coating with less than 420 grams per liter of volatile organic compound (VOC) content. It also resists diethylene glycol monomethyl ether (DiEGME), which is added to military aircraft fuels to prevent icing, to meet the Grade 2 classification.
The coating can help protect the interior of an aircraft’s fuel tank against corrosion from fuel contaminants such as water, salt water, aircraft fuels, hydraulic fluids, engine oils and dilute acid solutions, as well as DiEGME.
PPG CA7088 also being tested for qualification by military aircraft manufacturers, the company says.

Hexavalent-Chromium-Free Aluminum Sacrificial Paint Validation
Hexavalent chromium is a known carcinogen, repro-toxin and mutagen. Its elimination is of high importance to the aerospace industry, which has struggled to find high performing alternatives. Legacy aluminum sacrificial paints have traditionally utilized hexavalent chromium to prevent corrosion and coatings which are equal to or better than have been difficult. This second of two papers discusses the hexavalent-chromium-free process from the user point-of-view in terms of the process validation work by Rolls Royce Corporation.
