Phosphoric Acid Anodize

The best aircraft surface treatment method!

Phosphoric Acid Anodize (PAA) is the treatment of choice for critical applications in the aviation industry. Data collected from decades of use substantiates that Phosphoric Acid Anodize is the preferred method of surface treatment for structural bonding of aluminum alloys.

Bonds formed with Phosphoric Acid Anodize treatment exhibit superior durability than those formed by other treatment methods (Forest Product Laboratory Etching or Chromic Acid Anodize) during exposure to humid environments, especially when epoxy adhesives are used.

Phosphoric Acid Anodize treatment is just one of Avcorp's strengths. We are an aerospace manufacturer/ supplier whose products and services have been extensively tested and proven through real-world use.

The Phosphoric Acid Anodize treatment process was developed by Boeing in the late 1960's. Today, most primary structures manufactured for aircraft (fuselages, wings, control surfaces, wing boxes) utilize the Phosphoric Acid Anodize process to some degree. The US Military uses Phosphoric Acid Anodize on a large segment of its fighter, bomber, tanker, and reconnaissance aircraft. The world's largest aircraft supplier in the world, Boeing, uses Phosphoric Acid Anodize whenever aluminum bonding is required.
