Aluminum Rich Primer USAF Non-Chrome TIM 2017 January 2018 USAF Non-Chrome TIM 2017 Julia Russell/Brenna Skelley

Overview Background NAWC-AD has developed a non-chromated primer using an aluminum alloy pigment. This primer has exhibited corrosion performance superior to that of the current high-performance non-chromate primers the fleet is using. The Aluminum rich (Al-rich) primer has shown that it can perform well on aluminum and steel substrates, making it a MIL-DTL-53022 and MIL-PRF-23377 candidate. Outside of NAVAIR this primer may have benefits across the Department of Defense and in commercial applications. Public Release (SPR #: 2017-565)

Overview Key Technology NAWC-AD has developed a process for passivating the aluminum alloy pigment to give the coating greater resistance to self-corrosion and extended life to protect the substrate. Navy.mil Photo Public Release (SPR #: 2017-565)

Technical Accomplishments Continuing to optimize primer performance based on numerous composition variables Epoxy resin, metal pigment loading levels, inorganic inhibitors, solvent package, and anti-settling additives Testing scaled-up products produced by NAVAIR licensees Demonstrating products with Army, Marine Corps and Navy Aircraft and ground support equipment demonstrations Aluminum and steel substrates Public Release (SPR #: 2017-565)

Aluminum Rich Primer January 2017-- Al-rich primer was applied to a NET-4 trailer at NAS Oceana. Tow bar and axles topcoated with polyurethane topcoat Tow bar primed with Al-rich Tow bar and axle primed with Al-rich primer Public Release (SPR #: 2017-565)

Aluminum Rich Primer February 2017 -- Army H-60 demonstration at TASM-G in Groton, CT. Parts of an H-60 Black Hawk were painted with Al-rich primer. H-60 Stabilator H-60 Cargo Door Public Release (SPR #: 2017-565)

Aluminum Rich Primer May 2017 – Aluminum-rich demonstration over grit blasted steel on Spotting Dolly that will deploy on U.S.S. Stennis Fully assembled spotting dolly Aluminum-rich on chassis of spotting dolly Painter spraying aluminum-rich primer Public Release (SPR #: 2017-565)

Aluminum Rich Primer Demonstration Feedback Painters would like a tinted color so the Al-rich primer is not the same color as the metal Support equipment community would like dry to topcoat time reduced to 2 hours or less Technical Data sheet should specify that a 1.8mm spray gun tip is needed for Al-rich primer Navy.mil Photo Public Release (SPR #: 2017-565)

Aluminum Rich Primer Future Plans/Demonstrations August 2017- Al-rich primer was applied to a P-25 Fire truck at the Support Equipment FRC in Solomons, MD Fall 2017- Marine Corps mobile facilities will be sprayed with Al-rich primer at the Marine Corps Base in Albany, GA Fall 2017 – Al-rich primer will be demonstrated on Army H-60 parts at the TASM in Springfield, MO Army.mil Photo Public Release (SPR #: 2017-565)

Aluminum Rich Primer Transition efforts ONR Future Naval Capabilities project is supporting the scale up of Al-rich primer by licensees This summer, draft MIL-PRF-23377 specifications for a new class of primer to include the Al-rich, are being drafted Demonstrations on small scale assets and low risk areas will continue, with the goal of larger scale demonstrations in the near future Public Release (SPR #: 2017-565)
