Galvanic Plating is a process that uses electric currents applied to two opposite poles (negative & positive) in a tank of solution which contains the dissolved material of the coating. The product is attached to the negative pole and powered with a negative charge, while the metal dissolved in the solution is powered with a positive charge. The product then attracts the positive-charged metal in the solution, and thus, creating a thin coating of the desired material.
Epoxy is a tough and resistant thermosetting synthetic resin that contains epoxy groups. It is strongly resistant to corrosive chemical heat, and ultraviolet light, and is widely used as surface coatings, laminates, and adhesives.
