Powder coating is the technique of applying dry paint to a part. The final cured coating is the same as a 2-pack wet paint. Powder coating is a method by which electrically charged powder coating material is spray-applied to a grounded work piece. Electrostatic attraction holds the powder to the part to be coated until heat is added to melt the powder together and cure it, this forms a continuous film around the product.
To obtain the final solid, tough, abrasion resistant coating the powder coated items are placed in an oven and heated to temperatures that range from 160°C to 210°C (depending on the powder).
BENEFITS OF POWDER COATING
Powder coating gives a smooth, tough and resilient coating, because the powder is fused onto the product and forms a sealed skin which minimises corrosion and also has excellent scratch resistance properties. Powder coating is also an environmentally friendly method of applying paint.
In 2011 our oven was extended and can take lengths of up to 8.5 Meters.
We stock many colours and finishes and we can match with any special colours required, the choice of colours and finishes are almost limitless.
INSTALLATIONS AND MAINTENANCE
Once installed, maintaining the initial appearance of powder coating is a simple matter. Powder coatings should be washed down regularly (at least once each 6 months in less severe applications and more often in marine and industrial environments). The coating should be washed down with soapy water – use a neutral detergent – and rinsed off with clean water.
