Powder Coating
With increasing environmental and ecological awareness, paint manufacturers began searching for new solutions, and the first polyester paint resistant to outdoor conditions was produced in 1970. The powder coating process is highly dependent on the alloy quality of the profile. For example, the copper content in alloys 6063 or 6060 must not exceed %0.1, and the Mg/Si ratio must not be below 0.6. Furthermore, the raw material used must be homogeneous. Failure to meet these ratios can make the material more susceptible to filiform corrosion. Extrusion must be carried out in accordance with regulations, and the surface must be free of defects such as scratches, tears, or protrusions.
Powder Coating Process Stages:
Chemical Pretreatment: The environmentally friendly “Cromfree” process is applied to increase the adhesion of the powder paint to be applied to the profiles and the corrosion resistance of the substrate, and this process is controlled fully automatically.
Suspension Process: Profiles are suspended, taking into account the visible surface.
Powder Coating: The surface is coated with powder paint using a Super Corona gun.
Curing: After the powder coating process, the profiles move on to the curing phase.
Features of Powder Coated Products:
The specifications for powder-coated products are determined by the QUALICOAT specification. Powder-coated profiles achieve a decorative appearance while also offering high resistance to ultraviolet light and sudden temperature changes.
Production Capacity:
- Annual Capacity: The annual capacity of our powder coating facility has been determined as 18,000 tons.
- Maximum Profile Length: 7,000 mm (including suspension track distance).
- Layer Thickness: Minimum 60 microns.
This process produces high-quality, durable powder-coated aluminum profiles. At Kurtoğlu Inc., we offer environmentally friendly and aesthetically superior products.
