ESD (ElectroStatic Dissipative) Coating
ESD-coated surfaces prevent sparks, shorts, and sudden discharges that damage electronics or lead to explosions.
ESD coatings are partially conductive, which means also partially resistive to current flow, and can safely usher static electricity to an attached ground and prevent sparking.
By being only partially conductive, built-up charges don’t tend to jump to the coated surface all at once, as can happen with fully conductive materials like metals. In other words, the rate of charge transfer is slowed by the ESD coating. However, ESD coatings are conductive enough that static electricity can’t build up on them, the charges are dissipated.
