  • Full-surface bonded multiple component melt-spun nonwoven web
    Patent number: 7452832
    Abstract: A full-surface bonded multiple component nonwoven fabric is provided that has an improved combination of tear strength and tensile strength at lower thicknesses than known in the art. The full-surface bonded multiple component webs have a void percent between about 3% and 56% and a Frazier permeability of at least 0.155 m3/min-m2. The full-surface bonded multiple component nonwoven fabrics can be prepared in a smooth-calendering process.

  • Process for coating three-dimensional electrically conductive substrates
    Patent number: 6350359
    Abstract: A process for coating three-dimensional, electrically conductive substrates by applying a coating layer of a stoving coating composition substantially only to the exterior surfaces of the substrates at a layer thickness sufficient to electrically insulate such surfaces, stoving the coating layer and then coating the interior surfaces with an electrodeposition coating composition, wherein the stoving coating composition is characterised by a volume resistivity from 108 to 1011 Ohm·cm of applied and stoved coating layers of said composition.
