PPG recently announced that PPG RECC 3007 aerospace conversion coating has been qualified to U.S. military specification MIL-C-81706, Type II, Class 3, Form IV, Method A. It is reportedly the first non-chrome aerospace pretreatment coating to be qualified to the U.S. Department of Defense’s specification for chemical conversion coatings applied to aluminum. The coating is listed on the U.S. Defense Logistics Agency’s Qualified Product List.
PPG RECC 3007 pretreatment is formulated without chrome as an intentionally added ingredient. It is sprayed onto bare aluminum alloy aircraft surfaces to help protect against corrosion and improve adhesion for surfaces on which primer is subsequently applied.
“A key initiative for PPG is to offer aerospace coatings formulated without chromates and other chromium compounds that provide anticorrosion performance comparable to corrosion-resistant products formulated with chromium,” said Randall Brady, global segment manager, aerospace pretreatment solutions. “This military specification qualification enables all U.S. military branches and subcontractors to purchase PPG RECC 3007 pretreatment. It also enables commercial and general aviation aircraft manufacturers, operators and subcontractors that purchase qualified coatings to order the product.”
