Thermal stripping
For heavily coated parts which are not temperature-sensitive.
Thermal stripping is intended for heavily coated parts which are not temperature-sensitive, such as paint skids, gratings or hangers. These are stripped in pyrolysis furnaces at temperatures of up to 430°C, depending on the material the components are made of and how dirty they are.
After thermal stripping, two after-treatments ensure a clean surface and protection of the parts which are now stripped of paint: soft-iron granules remove the ash residue thoroughly and, at the same time, the surface is sealed, thus preventing excessive wear on the material. In chemical after-treatment, the parts are freed of ash, then of rust, and finally passivated.
