DESCRIPTION
Anti static powder coating is functional coatings used on surfaces in order to reduce or eliminate buildup of electrostatic charge. The cured surface is conductive in the range of kilovolts; at low voltages (< 1 KV) it acts as an insulator. Because accumulated electrostatic charge discharges at even higher voltages than the conductance threshold of powder film it is successfully dissipated prior any potential damage is made. Anti static powder coating is mostly used the electronics industry for protection of sensitive elements from high voltage discharge.
Often simply called ESD, electrostatic discharge is an abrupt and generally brief electric current that is created between two objects with differing electric capabilities. Though they can be small, the unwanted electrical currents can cause damage to electrical equipment. Static electricity is often the main culprit. Just as something as simple as rubbing a balloon on your hair creates static electricity - and the ESD event created is when your hair stands up - friction between objects is easily produced. It's usually brief, but the discharge can be significant and can negatively affect electronic equipment.
Problems caused by electrostatic discharge are usually found in the electronics industry where products can suffer damage if they are subjected to an electrostatic charge. As few as 100 volts is enough to damage an electronic component, so utilizing anti static powder coating can help add a protective film. Generally used for interior products, applications include electronic enclosures, cabinets, computer work stations, server casings, shelving, robot components and more. With so much reliance on the electrical items themselves, ensuring the safe, continued, dependable performance of electronic equipment is essential.
