Electrostatic Dissipative Coating (ESD)

Definition - What does Electrostatic Dissipative Coating (ESD) mean?

This is a surface protection application used in conductive technology on substrates that can produce electrostatic through a conductive surface, within a resistance range (105 to 109 ohms). It involves the use of coatings designed to dissipate charges from the various surfaces and also when the coating is required to have static dissipative properties on electronic appliances.

Corrosionpedia explains Electrostatic Dissipative Coating (ESD)

Electrostatic dissipative coating has been developed to curb the effect of charges developed on the surfaces of electrical sensitive equipment or components. They provide resistance from electric current flow. The coating drains static electricity in seconds, thus does not add any influence to the environment. This means that the substrate should be conductive material and a grounding mechanism has to be established.

The coating is mainly applied by an electrostatic spraying equipment, regardless of ambient relative humidity. Apart from prevention, it provides high aesthetic value after curing. It prevents a lot of corrosion by rejecting accumulation of particles, mar and microorganisms. The coating has ultimate resistance and excellent physical properties. The coating solvent enables the coating to mingle with the substrate. The improved electrostatic dissipative coating has resistance from UV radiation, hence retains its color and gloss appearance.
