QualiMarine compliant chemistry

The Qualimarine label, developed by the French aluminium association ADAL, defines strict standards for the surface treatment of coated aluminium intended for use in coastal and marine environments.

AD Chemicals offers a range of surface treatment products that are fully compatible with the requirements of the Qualimarine process. Our pretreatment solutions deliver outstanding corrosion resistance, paint adhesion, and process stability, supporting coaters and applicators in achieving high-quality and durable aluminium finishes.

What is Qualimarine?

Qualimarine is a quality protocol designed to enhance the durability and weather resistance of coated aluminium products, especially under corrosive conditions such as sea air. It includes specifications for:

• Aluminium pretreatment (degreasing, etching, conversion coating)

• Coating process control and quality assurance

• Traceability and documentation

• Corrosion resistance testing (e.g. salt spray testing)

Our pretreatment products are fully compatible with Qualimarine processes. They meet the surface preparation requirements defined in the Qualimarine protocol and are ideally suited for aluminium applications in coastal and marine environments.
