What is powder coating?

Basically, powder coating is paint in a powder form.

Powder coatings are used when a hard finish which is tougher than conventional paint is required. Basically anything capable of holding a small electrical charge can have powder applied to it.   It is usually used for coating metals, however, newer technologies allow other materials such as MDF and even glass and ceramics to be coated using different coating methods.

So how does it work?

Powder application is very simple.  The powder is applied to an object using an electrostatic gun.   Compressed air pushes the powder out of the gun, past an electrode which gives the powder a positive charge.  The object being coated is grounded so the positive powder particles are attracted to it.  When the object is completely covered, the ground is removed and the object is put into the oven to be baked. While in the oven, the powder goes through a chemical change where it becomes free flowing and forms a ‘skin’ around the object.  After cooling, the powder is ‘set’ and forms a hard finish.


What can I apply powder to?



Powder can be applied to items kept inside; including washing machines and lighting and also to exterior items including architecture and fencing.  Powders are capable of withstanding extreme environments, thanks to  intensive testing procedures.  The levels of powder durability are dependant on the mix of ingredients used.


The advantages of powder over conventional paint




Powder Coatings:



  1. •contain no solvent.

  2. •emit no VOC’s (volatile organic compounds)

  3. •can produce much thicker coatings without running or sagging

  4. •overspray can be recycled and reused (no wastage)

  5. •production lines produce less hazardous waste than conventional liquid coatings




Powder-coat is an addition to our existing spray-booth facilities.

We can sand- and bead-blast components prior to painting for the highest quality finish.




Ovens are maintained at a constant 200 degrees Fahrenheit.

Powder coating is not suitable for base materials which will not withstand continued exposure to these temperatures.
