On 01.08.2014 The European Patent Office has certified with European patent the FOX® technology developed by SAT, operating in 10 different countries in the world. The plant FOX® is integrated to the vertical coating system and allows to pre- treat the profiles with a flash oxide layer (between 3 and 8 microns) that protects excellently the metal and the coated layer from corrosion. The profiles are loaded on the paint line and proceed to the following process:
- Pre-treatment in a cascade tunnel
- Flash Oxidation
- Rinsing with demineralized water
- Drying
- Coating
- Polymerization
- Cooling
- Unload
All these steps are performed on the same line.
This means that the running costs of vertical lines with standard pretreatment and vertical lines with FOX are very close.
