    摘要: 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.

    摘要: A method for applying a thin coating to a flat side (front side) and edge surfaces of a two-dimensional formation of graphite foil, includes applying the coating material to the flat side (front side) to be coated by electrostatic powder spraying followed by a sintering cycle or melting cycle. During the spraying, the two-dimensional formation is electrically contacted on a limited area virtually in the middle of its rear side, facing away from the spraying direction, on a limited area at a distance of at least 5 mm from the edges. A method for heat dissipation in electronic equipment, is also provided.

    摘要: A method of applying a protective coating to a concrete or concrete-related substrate. The substrate is heated, and then electrostatically-charged coating powder is deposited onto the substrate with the coating powder coalescing into a coherent layer. Then the substrate and the coating are cooled to form the protective layer. The moisture content of the concrete or concrete-related material is sufficiently low so that bubbles or separation does not occur, and sufficiently high so that the electrostatically-charged particles will adhere to the substrate.
