Metal Bond

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.
Helping suppliers optimize manufacturing processes.
