  • Method for applying a powder coating
    Patent number: 9586232
    Abstract: A method for the application of at least two different powder coating layers to a substrate comprising the steps of application of a first powder coating layer followed by the application of a second powder coating layer, without any substantial curing of the first powder coating layer prior to the application of the second powder coating layer, followed by the simultaneous curing of the first powder coating layer and the second powder coating layer, wherein the first powder coating layer or the second powder coating layer comprises 1 to 10 weight % of a conductive component having a resistivity of below 5 ?cm at a packing volume of ?70%.
    Type: Grant
    Filed: March 26, 2013
    Date of Patent: March 7, 2017
    Assignee: Akzo Nobel Coatings International B.V.

  • Method for applying a powder coating
    Patent number: 9044779
    Abstract: A method for the application of at least two different powder coating layers to a substrate comprising the steps of application of a first powder coating layer followed by the application of a second powder coating layer, without any substantial curing of the first powder coating layer prior to the application of the second powder coating layer, followed by the simultaneous curing of the first powder coating layer and the second powder coating layer, wherein the first powder coating layer is applied to the substrate using a corona charging system and the second powder coating layer is applied to the substrate using a tribo charging system, or the first powder coating layer is applied to the substrate using a tribo charging system and the second powder coating layer is applied to the substrate using a corona charging system and the first powder coating layer and second powder coating layer have an opposite electrostatic polarity.
