What is the primary purpose of Alodine?

The primary purpose of Alodine is to provide a protective film that enhances corrosion resistance on aluminum surfaces. Alodine is a chemical conversion coating process commonly used in aerospace and other industries to treat aluminum and its alloys. This treatment results in a layer that protects the metal from corrosion and improves adhesion for subsequent paint or coating applications.

This protective film is essential for maintaining the structural integrity and longevity of aluminum components, especially in aviation, where exposure to harsh environmental conditions can lead to corrosion. The Alodine process not only improves corrosion resistance but also leaves the aluminum surface with a surface that can be further treated with paint or primer, ensuring better bonding and durability.
