Paint Pre-Treatmentsphopshate pre treatments

Paint or Powder Coated Finishes depend on the correct pre-treatment for the highest adhesion and corrosion resistance.

The MacDermid pre-treatment range includes cleaners for removing soils, aluminum conversion coatings, zinc phosphates and sealants.

To meet RoHS, WEEE and EOLV directives, our processes include Qualicoat and GSB approved chromium-free systems.

For multi-metal use we have cleaner phosphate systems which can be teamed with high-performance dry in place final seals to provide reliable, cost-effective pre-treatment for painting both steel and light alloys. These can be applied by immersion or spray depending on the application.


Iridite Qualicoat and GSB approved conversion coatings and adhesion promoters for use under paint and powder coating.
New Dimensions A range of innovative cleaners providing reliable water-based alternatives to solvent degreasing.
Sintklin, Masco A range of aqueous based cleaners for the cleaning of components before secondary operations or inspection. Nitrite, formaldehyde and boron-free.
