Abstract
A semi-insulating coating or surface layer is applied over insulating materials such as a circuit board or wiring harness or feedthrough insulator. The paint is electrically fixed to ground and as a result leaks away charge buildup before large pulse discharges occur. For example, pure tin oxide particles in phenoxy resin binder forms a paintable application for the invention.
