  • Patent number: 6926972
    Abstract: An electroluminescent (EL) coating system for a vehicle and a method of providing the EL coating system are disclosed. A dielectric coating composition is applied to a conductive substrate, such as an automotive body panel. Application of the dielectric coating composition, which includes an EL phosphor, forms a dielectric film layer on the substrate. A conductive coating composition, which includes an electroconductive additive, is applied to the dielectric film layer to form a conductive film layer on the dielectric film layer. The dielectric coating composition is disposed between the substrate and conductive film layer such that the conductive film layer remains spaced from the substrate. The EL phosphor in the dielectric film layer is excitable by an electrical field established across the dielectric film layer. As such, the coating system of the vehicle is EL, or ‘electroluminesces,’ upon application of an electrical charge to the substrate and the conductive film layer.

  • Publication number: 20050163765
    Abstract: The present invention describes a process for the preparation of an enzyme-containing granulate wherein an aqueous enzyme-containing liquid is, optionally supplemented with a solid carrier and/or additive ingredients, processed into granules, dried and subsequently coated with a polyolefin, preferably polypropylene and/or polyethylene. This coated enzyme granulate is suitable for the manufacture of animal feed compositions by mixing the granulate with feed ingredients, treating with steam and pelleting. The coated granulates show high enzyme stability during pelleting conditions and during storage. At the same time, the dissolution time of the granule is very short so that the bioavailability of the enzyme to the animal is improved.
