The most important benefits of powder coat

Nowadays, powder coating is suitable for a wide range of materials and purposes including metals, glass, MDF, and even wood and plastics. Powder coatings have many features and benefits that make them the coating of choice. Just a few of these are:

  1. Durability: It is more resistant to chipping, scratching, fading, and wearing than other finishes, importantly for South Africa, it also resists UV radiation better than most liquid coatings.
  2. Environmentally friendly: Solvent-free, very low/zero VOC, and excess powder can be recovered and reused, so minimal waste and under 1% material loss.
  3. Cost efficiency: It is cheaper than liquid paint, and is a one coat application with low operation costs.
  4. Flexibility: Suitable for a wide range of materials and purposes including metals, glass, MDF, and even wood and plastics.
  5. Appearance: Unlimited powder coating colours and finish choice (including smooth, textured, gloss, matt, iridescent, glitter, and candy) with thicker applications that liquid coatings and no running or sagging. Therefore powders are used for coating consumer goods such as furniture and appliances.

The powder coating process and application methods

Powder coating is a process where paint is applied to a substrate in powder form. Usually a paint is a binder and a pigment suspended in a liquid solvent, but a powder coat is solvent free, it is the binder and pigment blended into a fine powder. The application process can be broken into 3 steps: substrate preparation/pre-treatment, powder application, and curing.

Preparing the substrate

The correct preparation of the substrate is paramount in any coating application. Firstly, remove all oil, grease, dirt, grime and ensure that the part is completely clean. Then the part is stripped – this removes previous coatings. Finally the part is sandblasted. This stage cleans the part down to bare metal and creates a texture on the substrate which allows the powder coating to adhere to it. After a final clean the part is ready. This step is slightly different depending on the substrate.

The 2 application methods

Fluidised bed powder coating application.

Powder coatings are applied through one of two methods: electrostatic spraying, and fluidised bed. The spray application is recommended for DIY projects, for the DIY powder coating system supplier companies provide kits suitable for such application. Fluidised bed equipment and application are little more complicated.

  • The electrostatic spray process applies the powder through a specialty spray gun which gives the powder an electrostatic charge. This causes the powder to stick to the grounded part. These powders are used for instance by the appliances industry.
  • In the fluidised bed process, the part is heated and dipped into a hopper filled with fluidised powder. The heat melts the powder onto the part immediately, though a post cure may still be needed. Thermoplastics are less common, yet they are present in the automotive industry and other industries that deal with mass production.

Curing the powder coat

The final step is to bake the powder coat, causing it to melt, flow, and form a continuous liquid film. This ensures an even coverage over the part. Depending on the type of powder, there is either a further step for curing (for thermosetting powders), or the process stops here (for thermoplastic powders). Thermosetting powders undergo chemical crosslinking  when heated and will not melt again, where thermoplastics do not crosslink and will melt again if heated. A properly cured thermosetting powder is tough and impact resistant. When carrying out a powder paint project at home, usually the most cost efficient solution is to try to find a DIY powder coating system manufacturer or supplier who also provides instruments needed for curing.

The necessary industrial and DIY powder coating equipment

There are many pieces of equipment required for a complete powder painting facility. These range from sandblasting boxes or rooms and curing ovens at the large scale end to hanging racks and guns at the smaller. If you wish to buy powders and professional or diy powder coating equipment there are many suppliers operating across South Africa. The cost of equipment varies by scale and quality. A powder coating kit supplier usually includes hooks, air line, tapes and powder cups in the kit and asks up to R6.000 per powder coating kit. A gun system with a powder fluidising drum can cost R47.000.

The cost of powder is calculated by the pound or kilogramme, with greater quantities charged at lower rates. The less common or more specialised a colour, the more expensive it is. An average powder might cost R100-R190 per pound, but can be anywhere up to R480 a pound. The so-called solid powder coating colours are the most inexpensive and the price increases when metallic or pearlescent powder coating colours are requested.
