Why is pre-treatment so important?

Quality pre-treatment is necessary for the successful adhesion of the powder.  The pre-treatment process involves a chemical reaction on the surface of the metal to clean it of dirt, oils and grease, and then convert it into a chemical layer that is resistant to corrosion as powdercoating alone will not provide a corrosion resistant coating on metal.

This is a very important step in the coating process which is often underestimated by less competent coaters.  Accent Powdercoaters utilises the most recommended pre-treatment for aluminium, being a Full Chromate Conversion Pre-Treatment.

This seven stage process encompasses Acid Etch, Chromate Conversion, Demin Bath and the appropriate rinses.
