Structural bonding (Metal to Honeycomb) or Metal-bond (Metal to Metal) as it is referred to in the aerospace industry is a combination of chemical processes and adhesive bonded joints. The most common of which is Phosphoric Acid Anodize (PAA). PAA is one of the oldest bonding technologies still in use today due to the consistency and simplicity of its application. However, without having a thorough understanding of the chemical process of PAA including how the oxide structure is built and protected can lead to faulty parts and compromise quality and safety.
ACG is a leading expert in the proper execution of Phosphoric Acid Anodize processes. We have comprehensive beginner and advanced classes that can be conducted on-site with you tank-line operators. Understanding everything about PAA including racking, electrical current, current density, tank-line chemistry, primer spray and bonding can take years to develop and optimize functional systems and processes. We can provide classroom and on the job training to make your operators experts in the process of structural bonding.
