Powder coating is a type of coating that is applied as a free-flowing, dry powder to the metal. It is a polyester or epoxy powder, which is applied to an object and then heated to fuse into a protective layer.
The main difference between a conventional 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 and curing time is significantly faster compared to liquid coating,.
Because powder coating does not have a liquid carrier, it can produce thicker coatings than conventional liquid coatings without running or sagging, and powder coating produces minimal appearance differences between horizontally coated surfaces and vertically coated surfaces. It is also better for the environment, doesn’t require drying time and produces minimal wastage as overspray onto the part can be retrieved and reused, unlike with traditional liquid finishing methods. Several powder colours can be applied before curing them all together, allowing colour blending and bleed special effects in a single layer.
The coating is applied electrostatically and is then cured under heat to allow it to flow and form a “skin”. It is used to create a hard finish that is tougher than conventional paint and provides an attractive and durable finish, offering excellent resistance to corrosion, heat, impact, and abrasion and the choice of colours and finishes are limitless, depending only on what the manufacturers offer.
