Fluidized bed coating is a process in which preheated parts are immersed in a powder bath. This powder is kept in vortex by blowing air through the porous bottom of the bath. This causes the powder to behave as being a liquid. When the blasted and heated part is subsequently immersed in the whirlpool bath, the powder particles melt down as a solid layer.

Both small and large parts can be provided with a coating using a fluidized bed. Especially pipe sections, couplings and fittings are provided with coatings using this technique. Kersten has options to cover parts with a length of 6 meters and a diameter of approximately 1.5 meters within this process

The following coatings are suitable for application by means of fluidized bed coating:

• Rilsan®
• Resicoat®
• Abcite®

Fluidized bed coating has the following advantages:

• Specific parts with difficult-to-access surfaces can be coated easily and in a controlled manner.
• In one operation a layer thickness of 400μm is applied, both internally and externally.
• It is an efficient coating method with very low powder loss.

Friction creates heat and can lead to wear. Low friction resistance means little heat and less wear. These coatings are used in particular at high temperatures, where conventional oils and fats can no longer be used. Or in the foodbusiness in case products need to slide to or into their next position in the process.

Chemical resistance is the degree to which a coating is resistant to a specific chemical medium. The concentration of chemical substances and the temperature of the medium have a major influence on the level of resistance. We can advise you about the possibilities of our coatings.
