Two-layer dielectric coating

A coated substrate comprising a first coating layer comprising:

• an electrodepositable coating layer deposited from an electrodepositable coating composition, and
• a second coating layer comprising a powder coating layer on at least a portion of the first coating layer, wherein the powder coating layer is formed from a powder coating composition, and wherein the first coating layer and second coating layer form a multi-layer dielectric coating having a dielectric strength of at least 1 kV, as measured by a Sefelec Dielectrimeter RMG12AC-DC and in accordance with ASTM D 149-09 Hipot test;
• and
• wherein the substrate comprises a battery or a battery component, wherein the battery component comprises a battery cell, a battery shell, a battery module, a battery pack, a battery box, a battery cell casing, a pack shell, a battery lid and tray, a thermal management system, an inverter, a battery housing, a module house, a module racking, a battery side plate, a battery cell enclosure, a cooling module, a cooling tube, a cooling fin, a cooling plate, a bus bar, a battery frame, and/or a stationary energy storage system.
