  • 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

  • Electrostatic fluidised powder bed coating process
    Patent number: 7972660
    Abstract: The present invention pertains to a process for forming a coating on a substrate using a tribo-charging electrostatic fluidized bed process; characterized in that a powder coating is used which has a particle size distribution such that a) d(v,90)?42.5 ?m, and b) i) the percentage of particles <10 ?m in size is ?12% by volume, and/or ii) [d(s,90)÷d(s,10)]2?3.5, [d(s,90)?7]d(s,90) being greater than 7 ?m and d(s,90) and d(s,10) being measured in microns.
