Powder or Polyvinyl Coating of Magnets Desired.


We are producing magnetic "sticks" and attach these to non ferrous water lines for "softening" of the mineralized hard water that flows through these pipes. We need to protect these magnets (about 2x2x6 inches) from rust and corrosion and oxidation and wanted to powder coat these or dip coat them into a polyvinyl type of coating. Please send us any suggestions. Thank you.

Sir, we have found that fluid-bed dipping in a polyethylene powder has worked best for us in this situation. The key variable has been how the magnets get attached to the pipes. That affects how we can coat the units. Most of our experience has been with the magnets attached to a piece of sheet metal in groups of 3, 4, or 6 magnets. The sheet is then wrapped around the pipe and attached with latch-springs. If you are wanting the magnets coated individually, remember that there needs to be some way for us coaters to hang them, ie., a hole.
