Conductive Powder Coating

Conductive Powder Coating About

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 10 to 10 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.

Outstanding Conductivity and Durability

Engineered for applications demanding reliable conductivity, our conductive powder coating combines robust electrical performance with superior mechanical strength. It maintains a resistivity of 103 to 105 ohm-cm, ensuring effective EMI/RFI shielding for sensitive equipment. The coating's high impact resistance and flexibility allow it to withstand challenging operational environments, making it suited for both industrial and electronic-grade needs.


Versatile Finishes for Every Requirement

Choose from an array of finishes-including matte, glossy, semi-gloss, and textured-to meet aesthetic and functional preferences. Multiple shades and custom color matching are available, enhancing design flexibility. The fine powder formulation enables smooth, uniform coatings, while particle sizes of 30-60 microns ensure excellent coverage, up to 8-10 m2 per kg at 70-90 m film thickness.


Safe, Compliant, and Convenient Packaging

The powder coating is non-toxic and contains no lead, adhering to strict safety and regulatory standards such as RoHS, ASTM D3359, and ISO 8130. It is supplied in plastic laminated bags or drums, available in 1 kg, 5 kg, and 20 kg pack sizes, ensuring easy handling and storage. With a shelf life of 12 months, storing below 25C in a cool, dry place preserves its efficacy.
