Aluminium - Polyester powder coat
Fusion Facades are approved to provide polyester powder coated finishes offered by Axalta, Interpon D, IGP, Valspar and Tiger polyester powders. Polyester powder coating is an ideal finish for external applications where UV stability and weather resistance are essential, we utilise external architectural grade polyester powders to achieve this. It remains a popular choice with architects and specifiers due to the spectrum of durable finishes available. The range of special finishes available has grown dramatically in recent years with textured, metallic and anodic finishes now readily available. Powder Coating extends the life of the Aluminium as it is harder wearing than traditional painting or spraying with superior coverage being achieved in a single coat.
Powder coating is available with a lifetime guarantee. Our polyester powder coating finishes are guaranteed to BS 6496:1984 and BS EN 12206-1:2004 for aluminium for up to 30 years or more depending on surrounding environmental conditions. Environmentally – it is a solvent free, and any over sprayed product can be readily recycled.
The 3 phases of powder coating:
Phase 1: Pre-treatment – This is the most critical process to powder coating. We use a seven stage pre-treatment which is vital for the finish to perform to its full potential. Continuous monitoring of the chemicals involved avoids any risk of premature corrosion of the finish, flaking and/or chipping.
Phase 2: Coating – The pre-treated material is passed through fully automatic robotic spray booths to ensure an even coating. As the powder passes through the spray gun using compressed air, the particles are charged and as a result they are attracted to the substrate.
Phase 3: Curing – The powder coated material is then passed through an oven, allowing the temperature to increase to 200°c at its peak. The powder then melts and flows evenly over the surface before hardening.
Once curing is complete the material is inspected for defects, paint thickness, colour and gloss level.
Why is powder coating superior?
Powder coating providing consumers and industry with one of the most economical, long lasting, and most colour-durable quality finishes available. Polyester powder coated surfaces are more resistant to chipping, scratching, fading and wearing than other finishes. Colour selection is virtually unlimited with flat, satin, gloss, high gloss, metallic and textured finishes available. Colours also stay bright and vibrant for longer.
Powder coating is highly protective of our environment as it contains no solvents and releases only negligible amounts of volatile organic compounds into the atmosphere. One of the major factors in the success of the powder coating market has been the implementation of stringent air pollution control over the past thirty years.
