ALUMINIUM PRE-TREATMENT

The first step is to dip the product in Metal-Etch, a chemical solution. This process removes a layer of aluminium and leaves a clean white matt surface ready for chromating, This is then rinsed in a water booth to remove residual etch solution.

The next step is a Chromate dip, a conversion coating for aluminium which promotes excellent adhesion for the powder, as well as corrosion resistance. This step leaves the aluminium with a golden look, and is then again rinsed in a water bath.

The aluminium is then left to dry prior to the powder coating process.
