The complete guide to powder coating NZ – process to local specialists
The name probably gives it away. Powder coating, as the name suggests, is a method by which surfaces are coated with dry powder. The powder is then cured through heating so that it melts and flors, uniformly sticking to the surface. There are two forms of coating, and both application methods provide a strong scratch and corrosion-resistant finish to the coated surface:
- Thermosets – suitable for electrostatic spraying
- Thermoplastics – applied by dipping the object in a fluidised bath
Powder coating has become more popular than conventional paints. This is because of the number of advantages that powder coat has over liquid paints.

The industrial and commercial applications of powder coating
Powder coating has a number of industrial and commercial applications. Due to its benefits over conventional paints, it is being used to coat a number of different surfaces, but mostly steel. The automotive industry is one of the major industries that use powder coating significantly. Various car parts and motorbike frames are powder coated instead of being painted with liquid paints. The highest demand in this industry is the coating of wheels.
Other structures such as gates, fences and balustrades are also powder coated. Home appliances and furniture industries have also started using powder coats to paint their products. With the increase in sophisticated powder coating equipment, the number of applications is constantly rising. Interpon powder coatings by AkzoNobel are an example of an industrial powder line used for applications like offshore coating and industrial machinery. Interpon powder coatings come in a range of technologies and are available in New Zealand.
Do it yourself: powder coating at home
One can apply coatings to various types of tools and equipment to make them last longer. To begin with, you firstly need to understand what is the material that you are going to coat. You can then choose either a thermoplastic coat or a thermoset coat. After you have done so, you will need to make sure that the part you want to coat is separated from other parts. Next, give the surface a thorough clean. Use a powder coating gun spray to coat the surface. You will then need to cure the powder coating. This can be done by heating it using a heat lamp. The temperature needs to be adjusted. Usually, you will need to heat the object for ten to fifteen minutes at a temperature between 175° C to 190° C.
Using a coating gun and other methods of applying powder coating
The industry is ever-changing and evolving. A number coating equipment include automated complicated systems. There are also many other methods to prepare a surface for powder coating NZ. These methods include electro-coating. This can be achieved using automated tube systems. These are mainly found in high-end industrial plants. Other methods involve using abrasive blasting. Steel is also used to prepare a surface for powder coating. Once the surface is prepared, electrostatic guns can be used to spray the powder coating.
For home use, as mentioned earlier, powder coating gun sprays are widely used due to their affordable prices and ease of use. Small powder coating ovens can be purchased for curing purposes at home.
