Chrome-free immersion processes for aluminium and galvanized steel.
- The chemical pre-treatment chemical and procedure conforms to all current UK and European National Standards.
-
Monitored and controlled in our on-site laboratory in accordance with Qualicoat specifications.
- Material is fully submerged in a series of 9000 litre tanks containing:
- Cleaners to remove surface grease and oils.
- Etching agents to provide a key for powders
- Silane (galvanized steel) or Titanium Zirconium (aluminium) stages convert and seal the surface to form a "layer" that is corrosion resistant even before powder coating.
- De-ionised water rinses between and following the key processes stages, thoroughly cleaning and removing contaminants from the surface of the metal.
- 6-stage Titanium Zirconium (TiZi) technology process is used for aluminium
- 8-stage Silane process is used for galvanized steel.
- The unique process stages are separate for each metal and within an 11-tank in-line system.
- De-ionised water rinses separate each of the three critical stages
