Powder coating is a versatile and durable finishing process widely used in a range of industries, from automotive to shop fitting equipment and almost everything in between.
It was firstly introduced in the 1960s and has quickly grown in popularity over the years. Unlike traditional liquid paint, which is applied wet and then allowed to dry, powder coating involves the application of a fine powder, typically composed of finely ground particles of pigment and resin. What sets powder coating apart is its application method. The powder is electrostatically charged and sprayed onto a grounded surface, usually metal. The charged powder particles adhere to the surface, and once coated, the item is heated in a curing oven. The heat causes the powder to melt and flow, forming a smooth, durable, and uniform finish.
The powder coating process includes several key steps: surface preparation, powder application, curing, and cooling.
The foundation of any good coating is a properly prepared surface and so, before any powder is applied, objects are cleaned to remove dirt, grease, or other contaminants to ensure that the powder adheres to the surface effectively.
Once the surface is prepped, the powder is applied using a spray gun. The spray gun gives the powder particles a positive electrical charge as they leave the nozzle. Once an even coating is achieved, the coated object is placed in a curing oven. The heat causes the powder to melt and adhere to the metal. Once the curing process is complete, the item is removed from the oven and allowed to cool.
Powder coating protects surfaces from corrosion and makes them highly resistant to chipping and scratching. It is an extremely efficient process, with minimal waste since any overspray can be collected and reused. At Northpoint, we also offer a range of colours and finishes.
