1. A method for coating a plastic, metal and/or ceramic powder material with a coating containing a binder liquid activatable or laser light activatable organic or organo-meteallic adhesive, the method comprising:
providing particles of the powder material to be coated in a fluidized form in a gas phase; and
depositing the organic or organo-meteallic adhesive from a solution onto the particles of the powder material to form coated particles
wherein the particles, the coated particles or the gas space in which the particles are present in fluidized form are exposed to sufficient ionized particles to reduce the electrostatic charging of the powder material and/or the coated powder material.
