  • Processing of polymer based inks and pastes
    Patent number: 10920098
    Abstract: The present invention relates to a process of forming electrical conductor on a substrate comprising the steps of a) providing a substrate; b) providing an electrically conductive composition; c) applying said electrically conductive composition to at least one part of said substrate; and d) exposing said electrically conductive composition on the substrate to a near infrared light to form an electrical conductor. NIR light cure provides improved electrical properties of the cured composition without damaging heat sensitive substrates.
    Type: Grant

  • POSITIVE TEMPERATURE COEFFICIENT COMPOSITION
    Publication number: 20170257910
    Abstract: The present invention relates to a positive temperature coefficient composition comprising a semi-crystalline material, at least one binder, from 0.5 to 9.5% by weight of an electronically conductive material and a solvent. Furthermore, the present invention relates to use of a positive temperature coefficient composition according to the present invention in heating elements and sensors. A positive temperature coefficient composition according to the present invention provides low and stable resistance till self-regulating temperature, which allows fast heating of the heating element. Furthermore, the positive temperature coefficient composition according to the present invention has high PTC ration and therefore, has higher safety and more power can be applied to the heating element.
