  • Coating composition for metallic conductors and coating method using same
    Patent number: 6908692
    Abstract: An electrically conductive wire coated with a curable coating composition that forms a cured coating having a high partial discharge resitance and good mechanical properties. A process for coating an electrically conductive wire with a curable coating composition and curing the coating composition to form a coating having high partial discharge resistance and good mechanical properties.

  • Coating composition for metal conductors and coating process involving the use thereof
    Patent number: 6849822
    Abstract: A coating composition useful as an electrical insulation layer for metal conductors, particularly wires, that has improved de-coating properties for the partial de-coating of coated conductor by the use of laser irradiation; the coating composition comprises A) 1 wt. % to 90 wt. %, based on the total weight of the binder, of one or more binders, B) 0.3 wt. % to 25 wt. %, based on the total weight of the binder, of one or more reactive particles based on an element-oxygen bound network with elements from the series of aluminum, tin, boron, germanium, gallium, lead, silicon, zinc, the transition metals and the lanthanides and actinides, and C) 0 wt. % to 95 wt.

  • Process for the production of flexible protective, auxiliary and insulating materials on a fibre basis for electrical purposes, using impregnating massas which are curable by high energy radiation
    Patent number: 5405657
    Abstract: A process for the production of flexible impregnated protective, auxiliary and insulating materials on a fibre basis for electrical purposes by the application of an impregnating agent to the material to be impregnated, followed by curing, characterised in that a solvent-free impregnating mass containing one or more olefinically unsaturated, radically polymerisable polyesters, which contain one or more radically polymerisable monomers as reactive diluents, one or more plasticizing agents and optionally one or more peroxide-free radical initiators is applied to the material to be impregnated and curing is then carried out with high energy radiation and optionally by further heating.
