We ensure High Quality Pre-treatment before powder coating
As maximum powder application and adhesion are a prerequisite of a quality product, excellent pre-treatment is necessary.
✔ The pre-treatment consists of degreasing of the aluminium extrusion component, following by a chemical treatment.
✔ The chemical treatment provides good adhesion and effective corrosion resistance.
✔ After powder coating, controlled curing or stoving through large ovens which are computer maintained to ensure an effective and efficient process, takes place.
✔ Once removed from the oven, the powder coated aluminium extrusion component will be ready for careful packing. The powder coat thickness to the component is between 70 to 130 microns, depending on the powder utilized and the finish requirement
