The Three P’s of Powder Coating
Powder coating is the cornerstone of colouring technology in the manufacturing world, thanks to its extreme versatility, exceptional coverage and ease of application. Everything from cars, trains and planes through to tables, chairs and lamps can benefit from powder coating and the three P’s of powder coating will explain exactly how!
Unlike traditional paint jobs, powder coating takes advantage of an extremely technical application process. Rather than swiping the paint from a brush onto a piece of metal, powder coated items are first treated to an electrostatic treatment which makes the metal positively charged. The powder is sprayed through an electrostatic spray gun which gives the particles a negative charge, making the two attracted to one and other and forging a bond that is hard to unstick. This allows for precision accuracy during the application process, resulting in better more even coverage.
Another benefit of the aforementioned technical application is that powder coating creates a hard shell on the outside of the product rather than a soft one like paint would. This makes the colour extremely hardwearing and gives the material an added layer of resistance. Compared to paint which can chip or scuff fairly easily, powder coating is much more robust and less susceptible to erosion, meaning a long-lasting colour job that is unlikely to wear or tear or have a reduction in colour saturation.
Thanks to this strong outer coating that powder coating provides, products are better protected than they would be if left untreated or painted. Not only does this help to elongate the lifetime of the product but also makes it of higher quality generally. A bonus of choosing to powder coat items is that the powder contains no harmful chemicals or solvents, unlike paint and so businesses will be helping to protect their product, their customers and the environment.
