Powder Coating
P.P.C (Polyester Powder Coating) gives a extremely durable high-quality finish, it helps prevent rust and corrosion on metal products and surfaces whilst achieving the desired colour and finish. Powder coated products are more resistant to damage from impact and will resist chipping, scratching, fading, and other common wear and tear issues.
Polyester Powder Coating
Mettal utilise our own in-house polyester powder coating facilities. We have a fully automated track oven, which is used for fabrications such as small brackets, and long cladding profiles and extrusions of up to three metres.
Fabrications of a larger size can be accommodated in our static six-metre-by-two-metre box oven, which is complete with an overhead crane facility for heavier fabrications.
Techniques
Powder coating is a protective coating that is applied as a free-flowing, dry powder. Unlike a conventional liquid paint, powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form.
The coating is typically applied electrostatically, before being cured under heat to allow it to flow and form an “external outer layer”. The powder can either be a thermoplastic, or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional wet paint.
