HOUSING FOR PARKING METERS AND OTHER OUTDOOR TOKEN HANDLING DEVICES AND METHOD OF MAKING AND REFURBISHING SAME

摘要

A zinc coating directly covers a bare ferrous base of parking meter housing parts. A non-epoxy thermosetting electrically insulating organic non-epoxy powder coating directly covers the zinc coating. The organic coating is directly applied to the zinc coating by electrostatically charging the powder and parts with opposite d.c. voltage polarities and by heating the powder so it adheres to and covers the zinc coating. Alternatively, the base is zinc, directly covered by the organic powder coating.
