Powdercoating, Wet Spray & Electro Plating

Powder coating is by far the youngest of the surface finishing techniques in common use today. The basis of any good coating is preparation.

The vast majority of powder coating failures can be traced to a lack of a suitable preparation. Our five stage cleaning process prepares the products on the most economical way. There after the powdered paint is electrostatically charged and sprayed onto the part and then placed in an oven. The powder particles melt and coalesce to form a continuous film.

Our range of stock colors creates a wide range of possibilities. The choice of colors and finishes is almost limitless and can be ordered on request. Our fully automated plants allows us a great deal of flexibility in the market.

Powdercoating disclaimer

We have been running our in-house powder coating plants in excess of 25 years and during this period have gained valuable knowledge and experience with the procedure. The coverage and density of the powder especially on sharp edges has only become a real concern over the last couple of years due to the reduction and or removal of TGIC and Lead from the powder. These components have been reduced/removed due to government regulation worldwide as everyone’s goal is to go green and use more organic substances.

We believe it is our duty and responsibility to inform you our customers of the issues that can arise from choosing the incorrect material and or coating for the corrosion protection of your particular product. As a standard we apply a single coat of powder which is suitable for indoor use only and carries a 24 month warranty.
This warranty covers that the process of pre treatment and cure of powder coated products meets or exceeds the industry standard. S.P.E. warrants against cracking, peeling or excessive fading due to normal wear and tear, damage caused by mechanical abuse such as scratches, rough handling, installation or vandalism is not covered by this warranty.

For exterior, coastal or harsh environments alternatives must be investigated. Below please find some possible solutions:

  • Apply a Zinc based undercoat and then a final coat.
  • Zinc Plate products and then apply the final coat.
  • Change the base material to a galvanised, 3CR12 or Stainless Steel.

Herewith please find some information with regards to common issues related with Powder Coating as well as the corrosion levels of the country (Corrosion information).

Believe it or not the Highveld’s environment is just as corrosive as some coastal areas.
Powder coating is still one of the most cost effective coatings available as well as the most aesthetically pleasing, the key is knowing how corrosive the environment is and ensuring that the correct mix of components is applied.

Electroplating

Electroplating involves the coating of an electrically conductive object with a layer of zinc using electrical current. Usually, the process is used to deposit an adherent surface layer of a metal having some desired property (e.g., abrasion and wear resistance, corrosion protection, lubricity, improvement of aesthetic qualities, etc.) onto a substrate lacking that property.

The product finishes are as follows:

  • Yellow Passivated
  • Blue Passivated
  • Yellow Passivated with Superseal
  • Blue Passivated with Superseal
  • Plating with no Passivation – preparation for Powdercoating

Wet Spray Painting

Wet spray painting is a technique that involves the application of liquid paint in a consistent manner. The wet paint is transformed into an atomised mist which is sprayed on the surface to produce a uniform film of paint that offers resistance against chemicals, temperature and corrosion.

SPE has two wet spray lines, one includes a curing oven.
