Method and system for environmental sealing of electrical enclosures

Abstract

As described herein, an electrical enclosure is sealed against environmental contamination. An enclosure cabinet has an interior space. The interior space is accessible through an opening. A door or cover selectively closes the opening. The enclosure cabinet is manufactured of numerous parts and has holes, joints, gaps, seams and/or fasteners. Electrical control devices are mounted in the cabinet. A thick-film elastomeric coating is on an outer surface of the cabinet. The coating has a thickness of at least 0.6 mm to provide a monolithic bridging layer over holes, joints, gaps, seams and/or fasteners to prevent environmental contamination from penetrating the cabinet.
