An Overview on the Main Differences of Powder Coating and Spray Painting

12 May 2022

The parts and products used by the automotive, electronics, and other industries are often made from metals. While metal parts and products can easily withstand dents, dings, and other similar elements, they still require finishing to effectively protect their surfaces from weather elements.

Aside from weather elements, finishing can also provide these parts and products with a fresh set of appearance. Once the right type of finishing is utilised, business owners can conveniently make their offerings stronger, more appealing, and more valuable.

To date, business owners like you can opt for either powder coating or spray painting. Knowing the main differences between these finishing options can help you decide the best one for your application.

Powder Coating

Powder coating is a finishing process wherein powder is applied to the surfaces with spray tools. The powder is then heated to generate the desired colour coating of the involved parts and products. Most of the time, this process utilises powder made from acrylic, epoxy, polyester, and polyurethane. These ingredients allow the powder coating to yield a thick and consistent finish to the surfaces.

One of the benefits of powder coating is it can create a durable finishing. Powder coating allows users to generate a thick, adhesive finish that can last longer compared to spray paint finish. This process can also be done quickly and efficiently since it can already coat the whole surface in a single run. And despite a single run application, powder coating can maintain consistent results, preventing any markings from ruining the parts and products. Ultimately, powder coating does not produce toxins or waste during the entire process, making it eco-friendly.

Given the benefits of powder coating, it can be effectively utilised in coating everyday appliances, household fixtures, automotive assembly, and aluminium extrusions.

Spray Painting

Spray painting, on the other hand, can be carried out by applying aerosolised paint through high-pressure pump devices. Normally, these devices are powered by a pneumatic system, allowing industries to attain consistent, even coating in metal parts and products. By cleaning the surfaces before the spray painting process, industries can conveniently attain well-coated parts and products.

Like powder coating, spray painting can also provide great benefits to industries. For one, the spray painting process provides industries with a wide range of colour options. These options allow industries to produce parts and products with more colourful surfaces. Spray painting does not likewise require the use of an oven since wet paint can already dry on its own. This process also allows industries to apply thin wet paint to the surface and generate a smooth texture, which cannot be done by powder coating. Lastly, spray painting is affordable as it does not require expensive tools and paint materials.

All the benefits and features of the spray painting make it ideal for the restoration of parts and products. It can also be maximised in applications that require detailing and colour enhancements.
