Powder Coating Plants CED Coating

we build CED Plant. The Cathodic Epoxy Electro Coating Plant electrically deposits the paint on the metal part or a component by assuring the organic finish. This works on the simple principle of ‘Opposites Attract’.

Process
A DC charge is applied to a metal component immersed in a bath comprising of oppositely charged paint particles. The paint particles deposit on the component to a point where the coating reaches the desired thickness and an even, continuous film is formed over every surface, crevice and corner. On attaining desired thickness, the film insulates, resulting in stopping of attraction between paint particle and the component, thus completing the process. Depending upon the end use, you can choose either protective, decorative or a combination electro coating.

What is CED / Electrophoretic Deposition?

• Electrophoretic deposition (EPD), is a term for a broad range of industrial processes which includes electrocoating, cathodic electrodeposition, and electrophoretic coating, or electrophoretic painting.
• 
  A characteristic feature of this process is that colloidal particles suspended in a liquid medium migrate under the influence of an electric field (electrophoresis) and are deposited onto an electrode.
• All colloidal particles that can be used to form stable suspensions and that can carry a charge can be used in electrophoretic deposition. This includes material classes such as polymers, pigments, dyes, ceramics and metals.
• The process is useful for applying materials to any electrically conductive surface.
• The materials which are being deposited are the major determining factor in the actual processing conditions and equipment which may be used.
• Due to the wide utilization of electrophoretic painting processes in many industries, aqueous EPD is the most common commercially used EPD process.
• However, non-aqueous electrophoretic deposition applications are known. Applications of non-aqueous EPD are currently being explored for use in the fabrication of electronic components and the production of ceramic coatings. Non-aqueous processes have the advantage of avoiding the electrolysis of water and the gas evolution which accompanies electrolysis.
