摘要：Hitherto, glazing defects have arisen during glazing of ceramic substrates withan electrostatically applicable coating powder. This problem is solved by the inventivecoating powder CPAB and the coating method. The electrostatically applicable coatingpowder CPAB contains 1 to 50 wt. % of a glass-forming composition A which beginssoftening at 400 to 750 °C and 99 to 50 wt. % of a glass-forming composition B whichbegins to soften above 750-1,100 °C. Preferably, the coating powder consists of 2.5 to 25wt. % A, 75 to 97.5 wt. % B and 0 to 20 wt. %, specially 2 to 10 wt. % of thermally orchemically activatable adhesive agents. The coating powder CPAB is electrostaticallyapplied as a single powder. Alternately, coating can be applied in two layers, wherein theCPU powder contains at least 5 wt. % of glass-forming composition A as a lower layerand the powder CPO contains at least 50 wt. % of glass-forming composition B as an

upper layer.
