Staining of metal in the KTL process

Every metal surface is full of oxides that can be removed by staining. You can think of a mill scale and laser skin.

Staining with Maas coating can be done in 2 ways:

  • Staining bath (for staining steel)
  • Spray tunnel (for aluminum stains and galvanized steel)


Stain bath

One of the baths in our E-coat / KTL range is a stain bath, in which we can only pre-treat steel in the process for KTL / E-coat.

After staining and rinsing, zinc phosphating takes place. This is also done by immersing in a bath. Applications include staining stainless steel, staining of metal, aluminum staining and steel staining.

Spray pre-treatment tunnel

The other method is the spray tunnel with 6 process steps. Here we can degrease aluminum and galvanized steel (stain). This is also a chemical pre-treatment, where we can pre-treat lengths up to 7 meters.
