Antistatic prepainted coil

The working principle of antistatic prepainted coil is to add some conductive materials in the insulating polyester coating, which gets the original insulated coating into a semiconductor (surface resistance 106-1090Ω, the ordinary polyester coating around 1013Ω). With the installation of construction to the ground, the accumulated static electricity on the surface of the prepainted coil that is sourced from air convection or fabric friction is conducted into the earthing system and then disappear. It can prevent dusts and bacteria adsorption to decrease performance, prevent electricity discharge.
