Powder coat aluminium; don't paint aluminium
Powder coating aluminium
In 2003 we removed our 8-stage chromate pre-treatment system, operated to BS6496 and adopted an alternative Qualicoat approved system.
Due to our reputation with a large box oven, the sizes of the work we were asked to process were larger then our pre-treatment tanks. The replacement pre-treatment incorporates chromate solution in an acrylic resin, which encapsulates the treated metal.
We are now able to pre-treat and powder coat large aluminium components as long as they will fit in our box oven 11m x 4m x 3m.
Tri-Resin™ System (Aluminium)
Polyesters are not as impervious to moisture as was once thought. The Tri-Resin Powder Coat System is a coating system involving three different paint resins to seal the metal against moisture that can permeate through one coat of paint. This thicker coating is more aesthetically pleasing producing a thick luster finish. The Tri-Resin System has been used on aluminium window frames to 9m footbridges.
