    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.

  • Publication number: 20030236344
    Abstract: The present invention relates to methods of producing syndiotactic polypropylene articles through high performance nucleation via the presence of certain novel nucleating agents within molten syndiotactic resins, and subsequently permitting the resultant molten mixture to cool into a selected shape or configuration. Such novel nucleating agents are new classes of hyper-nucleators that promote crystallization within such target syndiotactic resins at levels well above any previously disclosed nucleators. This invention thus also encompasses the articles and compositions of such nucleated syndiotactic polypropylene as well.
