Powder Coating

Powder Coating is a process in which aluminium or hot-dip galvanised steel workpieces are coated with polyester or polyester-epoxy powder. 

After a special chemical pre-treatment of the surfaces, the coating material is applied with powder spray guns. It is distributed over the surface by electro-static charging (EPS). The powder is then baked in an oven at a temperature of approx 180 degress celcius and is turned into a layer of paint or lacquer. Powder coating makes the material weather-resistant and gives it a high level of corrosion protection.

By recovering the colour powder that does not remain on the product ("overspray"), the loss of colour and raw materials can be largely avoided during powder coating.

Additonal Addvantages of Powder Coating:

  • Versatile and durable 
  • Multifunctional
  • Coating thickness, colour and quality control
  • Environmentally friendly
  • Fast process providing a decorative look

Powder coating is a fast environmentally friendly process that provides metal products with many factors. These factors include versatility, durability, mulitfunctionality, and the ability to create almost any look you want on a metal product substrate.

Powder coating works with heat and electromagnetic attraction rather than with volatile organic compounds (VOCs). This process avoids toxic substances and reduces waste. Any overspray can also be collected and reused and is non-toxic. These factors make powder coating an environmentally friendly process. 

Some products that we offer with a powder coating include our A-Frames, Snap Frames, and Table Trolley along with many more. Check out our website now to discover other looks that fit your needs and wants. 

Steps of the Process:

The process of powder coating is made up of three basic steps:

1. Preparation or Pre-Treatment is the removal of all dirt, grease and other lubrications, metal oxides, etc. to create a clean surface before the process of powder coating begins. There are many different methods of preparation for powder coating depending on the product and application. 

2. Powder Application includes the metal product being sprayed with powder using an elecrostatic gun. This tool gives the powder an elecrtostatic charge and sprays toward a gounded object with either mechanical or compressed air. After being sprayed, the object is then heated and and the powder melts into a uniform coating. Once uniform, the object is cooled to form a hard coating. 

3. Curing can be done is a couple of different ways. Either with thermosetting or with a UV Cure. Thermosetting is done with high temperatures for a specific amount of time in order to create the film properties for which the material was designed.  UV curing uses Ultraviolet to create the film but in less time than thermosetting. UV curing is faster and is used for heat sensitive materials and assemblies. 


What Powder Coating can Provide for your Products

Powder coating is a process that provides products with a tough surface. The coating is strongly bonded to the surface of the substrate with an electostatic charge. This coating can last sometimes up to 20 years.

Powder coatings can also provide products with a protection layer, which increases abrasion, chemical, electrical and corrosion resistance. This coating also makes a smooth surface that can be easily cleaned. Surfaces can be made more unifom and thick with this process than with other plastic coating processes. 

Powder coating is a fast processesing technique. This means production time is also shortened. The fast decorative look provides many optic options for products. These options include: any colour possible, different desired texture surfaces, and gloss or matt finishes. These effects cannot be done with other coating techniques.
