Cleaning for Powder Coating

Q. Can Alconox assist with pre-powder coat cleaning?

A. Yes! To get the best powder coating results, you will need a residue free surface. And residue free is where we excel!

The detergent you use in precision manufacturing cleaning will depend on the material being coated. For non-aluminum surfaces, we recommend that you use a 1-2% solution (10-20 mL/L) of KeylajetⓇ Low Foaming High Alkaline Liquid solution to surfaces prior to powder coating.  Keylajet detergent will remove oils, particles, rust, and oxidation to leave a surface ready to bond with the powder coat.

The reduction in surface oxides greatly helps with adhesion. The surface is made more receptive to accepting the coating.

If you are cleaning aluminum, use a 2% (20mL/L) solution of our CitrajetⓇ Low Foaming Acid Cleaner for the same results with an aluminum-safe cleaner.  Solujet® Low-Foaming Phosphate-Free Liquid can be considered if difficult organic residues are in play with the aluminum substrate.
