Chemical conversion coating

Protection and adhesion for aluminum

In a chemical conversion coating process, the surface of aluminum is chemically oxidized while maintaining electrical conductivity. This creates a thin conversion layer that protects against corrosion. This process is also known as alodining. A chemical conversion coating results in a surface finish ranging from clear to gold/brown iridescent. Due to its excellent adhesion properties and protection against filiform corrosion, a chemical conversion coating is an ideal pre-treatment for paint systems. It is also commonly used on sealing surfaces and to promote and/or maintain electrical conductivity.

We offer several options for chemical conversion coatings, such as Alodine 600, 1200, and 1500 (not RoHS-compliant), as well as Surtec 650A and Socosurf TCS-PACS (both RoHS-compliant).
