  • Method and system for environmental sealing of electrical enclosures
    Patent number: 10362698
    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.
