  • Process for coating apparatuses and parts thereof
    Publication number: 20040157043
    Abstract: A process for coating surfaces in apparatuses or apparatus parts for plant construction, preferably for chemical plant construction, involves optionally first hydrophobicizing a polymer film having a microstructure and optionally additionally macrostructured surface and then fixing it on the apparatus or apparatus part to be coated, and also apparatuses and apparatus parts thus coated.

  • Method for rendering surfaces resistant to soiling
    Publication number: 20040047997
    Abstract: Surfaces are provided with a dirt-repellent treatment by a process in which the surfaces are coated with particles which have a mean diameter of from 3 nm to 5 &mgr;m and consist of a material which has a surface energy of at least 20 mN/m.

  • Compositions for producing difficult-to-wet surface
    Patent number: 6683126
    Abstract: The present invention provides a coating composition for producing difficult-to-wet surfaces, comprising i) at least one finely divided powder whose particles have a hydrophobic surface and a porous structure characterized by a BET surface area (determined in accordance with DIN 66131) of at least 1 m2/g, and ii) at least one film-forming binder characterized by a surface tension <50 mN/m, the weight ratio of powder to binder being at least 1:4. It also provides a process for producing difficult-to-wet surfaces, and provides for the use of the coating compositions for producing surfaces having a self-cleaning effect and for reducing the flow resistance for liquids in pipes.

  • Composition for producing surfaces which are difficult to wet
    Publication number: 20040014865
    Abstract: The invention relates to a composition comprising at least one hydrophylic, inorganic powder (P) having an average particle size of between 15 and 500 &mgr;m, and at least one hydrophobic, thermoplastic substance (T) which is characterised by a surface tension of between 20 and 50 mN/m. The weight ratio of the hydrophylic, inorganic powder to the hydrophobic, thermoplastic substance P:T is between 50:1 and 1:2.
