ELECTROPHORETIC


ELECTROPHORETIC COATING (BLACK)

Not to be confused with Electrostatic Spraying, Electrophoretic Painting or Electro painting, it bears some similarity to Electroplating. This modern method of paint application relies on the effect of Electrophoresis and involves the migration of colloidal particles in a solution such as a water based paint under the action of an applied controlled electric field. Under certain conditions the particles adhere to the electrode to which they are attracted and it is this property which has been utilized as a method of applying protective and decorative coatings.
The advantages of Electrophoretic Deposition are: 1. Controlled thickness. 2. Elimination of runs and sags. 3. Good coverage of sharp corners. 4. Penetration between spot welded surfaces. 5. Hardness of coating after stoving. Therefore, as with Electroless Nickel Plating, this process has great advantages in hi-tech precision engineering with the added advantage that one process compliments the other. Normal thickness of coating 10-15 microns masking is possible.
