Why use powder coatings?
Powder Coatings provide a stronger resistance and higher durability than traditional liquid coating techniquse with a vibrant and higher quality finish.
The prices of powder coatings are seen to be the most cost effective method of metal finishing, as new formulas and developments introduce techniques that can also be used at a lower temperature and can be used on a wider range of substrates.
Powder coatings can be used on various materials and products, such as cars, ships, yachts and boats; air machinery, buildings and finishings and metal structures. Thermo setting powder coatings are now generally recognized as having a significant role in the metal finishing industries and provide a great finish from a fast coating process.
Powder coating is a dry finishing process. In essence, it’s a paint in powder form which is electrically charged as it is sprayed onto a surface to be coated and then baked in an oven, where the powder particles melt and fuse into a smooth powder coating. The result is a constant, resilient, high quality environmentally safe with an attractive finish.
Spray powder coatings are a free flowing powder, as such they do not require a solvent to hold a binder and filler in a liquid suspension. The powder is applied electrostatically then cured under heat to allow it to flow and form a protective “skin”, this process creates a harder and stronger finish than other paints.
Products exposed to moisture, chemicals, ultraviolet light and extreme weather conditions are better protected with powder coated products as it reduces the risk of scratches, chipping, abrasions, corrosion, fading, and other wear issues. Powder coatings protect many of the machines, machinery and household items that you use day-to-day.
Powder Coating Benefits
- Corrosion Resistant
- Ease of application
- Energy costs are greatly reduced
- Coating process is easily controlled and automated
- Virtually all over-sprayed powder can be recovered for re-use
- Processing times for powder are generally shorter than for liquid coatings
- High film thickness can be achieved with a single coat without runs or sags – no primer is required
- No VOC’s and no solvents
- Minimum waste and associated disposal costs
- Powder Coatings require no pre-mixing, viscosity adjustments or stirring
- Air conditioning requirements are cut down as all air is typically returned to the plant
- Reduced health risks for operators – e.g. fewer hazardous materials and powder is easily washed off

Powder Coatings and Aluminium
When using powder coatings on aluminium, it gives you the range of colour freedom, and has the added plus of enhancing green credentials. The powder coating protects the aluminium substrate from weather, therefore from oxidation or filiform corrosion. But nowadays it also offers an added benefit – reflection of solar radiation, which keeps the metal and therefore the building cool.
Powder coating can be used on different aluminium parts, such as wheels.
Powder coated aluminium is simple to clean.
Aluminium powder coatings do not require any form of painting or staining.
