  • Electrostatically applicable coating powder and processes therefor
    Patent number: 6350495
    Abstract: Hitherto, glazing defects have arisen during glazing of ceramic substrates with an electrostatically applicable coating powder. This problem is solved by the coating powder CPAB and the coating method. The electrostatically applicable coating powder CPAB contains 1 to 50 wt. % of a glass-forming composition A which begins softening at 400 to 750° C. and 99 to 50 wt. % of a glass-forming composition B which begins to soften above 750-1,100° C. Preferably, the coating powder consists of 2.5 to 25 wt. % A, 75 to 97.5 wt. % B and 0 to 20 wt. %, specially 2 to 10 wt. % of thermally or chemically activatable adhesive agents. The coating powder CPAB is electrostatically applied as a single powder. Alternately, coating can be applied in two layers, wherein the CPU powder contains at least 5 wt. % of glass-forming composition A as a lower layer and the powder CPO contains at least 50 wt. % of glass-forming composition B as an upper layer.

  • Electrostatic coating powder for glass, ceramic or metallic substrates
    Patent number: 6270854
    Abstract: An electrostatically applicable coating powder is provided which contains a first powder which forms a glass layer upon firing, and 0.01 to 1% by weight of a salt of a carboxylic acid. The coating powder is free of organosiloxane and preferably contains a chemically or thermally activatable resin. The invention also provides methods for preparing the coating powder and methods for coating glass, ceramic or metal substrates with the powder.
