Powder Coating

A type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the 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 and is then cured under heat to allow it to flow and form a “skin”, creating a hard finish that is tougher than conventional paint.


Method of coating metal for corrosion resistance, electrical insulation, thermal control, abrasion resistance, sealing, improving paint adhesion, and decorative finishing. Anodising consists of electrically depositing an oxide film from aqueous solution onto the surface of a metal, often aluminum, which serves as the anode in an electrolytic cell. In the most common type of anodizing, which uses a 15% sulfuric acid bath, dyes can be introduced into the oxidation process to achieve a coloured surface.


Application of a plate, or coat, of metal to a surface for decoration, reflection of light, protection against corrosion, or increased wearing quality.


Smoothes and streamlines the microscopic surface of a metal object.


Coatings such as Primers, Epoxies and Polyurethanes used to protect against corrosion.
