Pre-anodising to be examined
for ali coating
17th October 2017

The Qualicoat organisation has set up a working group to look into pre-anodisation as an alternative preparation for aluminium powder-coating in the light of the imminent ban on the use of chromium in pre-treatment.

More than half of the Qualicoat licensed plants are now chrome free, says the organisation, while others are getting ready for the switch.

Pre-anodising, sometimes called flash-anodising, has been used for a number of years on the continent for the ‘Seaside Class’ of powder coating under the Qualicoat Standard, but the organisation says the benefits could be extended to regular projects where a more robust finish is required, specifically where cut edges are going to be exposed.
