Preventing e-coat build up
Modern car bodies are protected from corrosion by being dipped in e-coat, but this e-coat also builds up on the car body carrier frames.
E-coat, or electrophoretic coating to give its proper title, is a corrosion resistant coating applied beneath the decorative paint finish. The part to be treated, in this case the base car body (known as the "body in white" in the industry) is moved into the bath of e-coat attached to a carrier frame. An electrical current is passed though the frame and hence the car body which ensures the e-coat reaches and bonds to all parts of the car body. The frame is lifted from the e-coat bath and on through washing tanks.
Over time three things happen.
The e-coat attaches itself to the carrier frame. This wastes e-coat and adds weight to the frame which can strain the motors driving the frames.
The electrical charge can arc from the incoming section of the frame to the car or other parts of the frame, potentially causing damage.
As the e-coat builds up on the frame it can start getting transferred to the cleaning tanks, thus contaminating them and wasting the e-coat.
The solution? Impreglon has a perfect coating which we've applied to many carrier frames and associated equipment. It works. Not the cheapest coating on the planet but it works month after month after month.
