A quick guide to POWDER COATING?

It is a part of our lives every day, coating everything from household items and vehicles to heavy duty machinery, it even protects and beautifies countless artwork. It’s popularity comes down to two things: protection and style. As a coating method it is flexible, durable, highly protective, and its strengths are not at the cost of its looks. The range of powder coating colours and finishes is wide, which ensures your project looks and performs exactly as you need. The process has actually been around for fifty years, and it’s found in many common products and materials. The beauty of this particular method is that there are many controllable elements, such as colour, texture, and finish, all of which can be formulated to meet your desired specifications.

The powder coating process in 3 steps

Preparation

Surfaces must be cleaned and protected. In other words, most powder coat providers will prep the surface to ensure smooth adhesion by utilizing sanding or a brush blast. It’s also necessary to protect any parts that you don’t want to treat, just as you would when painting a more traditional surface. This is a little more complicated with something like powder coating, as the static charge can be quite strong, but that’s why proper preparation is key. Sometimes, depending on the end result desired, there is also a pre-treatment involved, in which the surface is given a primer coat to achieve a specific result.

Powder application

The second main step in the process is the coating itself. During this process, the surface to be coated is grounded. Again, this is one of the reasons why metal objects are a popular choice, but it’s worth mentioning again that they are not the only choice. The powder itself is applied using an electrostatic gun (sometimes called a corona gun), which essentially shoots electrically charged particles of the dry powder at the grounded surface. The electrical connection means that those particles are attracted to the surface and remain in place until the curing process begins.

Curing

During the curing phase, the coating is exposed to high temperatures rapidly and this hardens the powder coat in place. Sometimes during an advanced powder coating procedure, a surface can be “pre-heated” to bolster the curing process. Once the curing has melted the powder, the surface is then quickly cooled, hardening the materials in place. As mentioned above, the curing process makes powder coating particularly durable and chip resistant

Taranaki Powder Coating are just great to deal with. Their work is excellent. They have efficient systems and their communication is excellent. I highly recommend them.

Rex

When I saw their finish on some vintage tractor parts I was amazed. The powder coated parts had a deep green John Deer colour to them. Excellent workmanship.

Powder Coating outdoor awning parts adds so much duration to the life of the parts. Because we live close to the sea Taranaki Powder Coating process was the answer for corrosion prevention of our parts.
