Conductive Powder Coating

Specifications:

Product details

Product Features:

Dissipates static electricity to protect the normal operation of low-voltage or micro-electronic components.

Prevents the occurrence of electrical sparks and the accumulation of static electricity, which can cause static fires or injuries.

Can be formulated according to customer requirements for conductivity, with a range of 10⁴ to 10¹² ohms (adjustable).

Excellent adhesion, impact resistance, scratch resistance, flexibility, and high hardness.

Conductive powder coatings are functional coatings that, after application and curing on a substrate, can conduct electricity and dissipate electrical charges. They are used for static elimination, electromagnetic shielding, electric heating, and corrosion protection, and have wide applications in modern electronics, construction, transportation, military, and other fields.

Doped conductive powders offer moderate pricing and good conductivity, but with limited color options, primarily available in dark colors or with speckled patterns.

This product is a conductive powder primarily composed of polymers, conductive pigments, conductive fillers, and conductive additives. It offers a variety of colors to meet customer requirements. The conductive mechanism, based on quantum mechanics, involves the mixing (overlap) of molecular orbitals in polymers, which generates charge carriers and exhibits electrical properties. For conjugated chain polymers, intrinsic charge carriers (electrons and holes) are produced, displaying unique electrical properties, photoelectric effects, and light-conducting effects, and can form rectifying junctions.
