Process for recycling powder coating waste

摘要

A process for recycling of powder coating waste comprising the steps of (1) compressing powder coating waste to powder coating compacts having a volume of 0.5 mm³ to 15 cm³ by applying pressing forces; (2) placing the formed powder coating compacts into a vessel, rotating the vessel about a rotational axis inclined at an angle of 20 to 70 degrees relative to the horizontal and (3) heating the powder coating compacts while being moved in the rotating vessel until through-glassed powder coating bodies are formed.
