nly clean metalic surfaces enable coatings to adhere perfectly. The most important basis is an optimal pre-treatment. Lubricants such as fats and oils, polishing agents, particles of dirt and oxidation products must be completely removed from the metal surface in order to guarantee a high coating quality. For achieving this, ElectroChem Technology product range contains a number of highly efficient processes and products. 

What are the properties the workpiece must exhibit after the coating?
• Does the corrosion protection have priority? Is a decorative finish required?
• Or do purely functional properties have priority?
• Or a combination of all these requirements?

Your requirements are decisive when choosing the process!
