Electrostatically applicable coating powder for ceramic coatings

The deposition of ceramic coatings on combustible substrates by electrostatic processes using coating powders has so far been expensive and the quality of the coatings has been unsatisfactory. The invention overcomes these problems. The coating powder of the invention consits of a powdered stovable...

Beschreibung
Zusammenfassung:	The deposition of ceramic coatings on combustible substrates by electrostatic processes using coating powders has so far been expensive and the quality of the coatings has been unsatisfactory. The invention overcomes these problems. The coating powder of the invention consits of a powdered stovable material with a d90 of under 35 mu m, a d50 in the range from 5 to 25 g(m)m and a d10 of 2 mu m or over and a physically or chemically activable powdered organic material. The coating process comprises the electrostatic application of the coating powder, the physical or chemical activation of the bonding agent and stoving the coated substrate. Fautless coatings are obtained.
