Electroplating Business 

The Donauchem Kft., started the cooperation with the Coventya in 2005. COVENTYA is a worldleader company in specialty chemicals for metal plating, electroless nickel, electroplating and water treatment.

A few examples of industries which use Electroplating

  • Automotive industry
  • Building industry
  • Tapes and sanitary fittings industry
  • Electrical equipment industry
  • Connectors industry
  • Electronic industry
  • Jewellery industry
  • Spectacle frame industry
  • Leisure industry (sports, cycles...)
  • Lighting industry

The major application where Donauchem Kft. recommends the technology and materials in electroplating by Coventya.

Pretreatment 

The most important aim of this step is the removal of the majority of all kind of contaminations, and removal oxides and carbon deposits from the surface.

PRELIK and PRESOL cleaners are able to degrease the surfaces as a:
  • soak cleaner and/or
  • electro cleaner
To improve the surface pretreatment of most common metals:
  • PICKLANE which removes the oxides

Decorative application

When the most important aspect is not only to protect the substrate from corrosion, the appearance is also considered we have solutions even if the substrate is made from steel, zinc, copper or ABS.
  • nickel
  • chromium
  • copper (acid, alkaline application)  

Protection application

We can collaborate with pure zinc and zinc-alloys applications.
  • Acid zinc
  • Alkaline zinc (cyanide and non cyanide applications)
  • Zinc-alloys: zinc-nickel, zinc-cobalt, zinc-iron
  • Passivates: trivalent chromium and hexavalent chromium with several colors ( blue, yellow, black, transparent)
  • Self-healing top-coats  

Functional application

It is possible to improve the weldability, conductivity, ductility, hardness, abrasion qualities of the substrate. We have several technology to change the behavior of the metal:
  • Electroless nickel
  • Tin application
  • Special applications: silver, gold and palladium applications

Further information is available on Coventya's web-page.

Our product managers provide regular contact as required by the customer, providing technical support and offering a swift and flexible response to customer needs.
