Conductive paints

Conductive paint is a blend of electrically conductive pigment in a non-conductive binder. The binder provides adhesion, while electrical charges move through the conductive pigment. The effectiveness of this depends on the concentration and shape of the conductive fillers. Various fillers differ in conductivity, corrosion resistance, and cost. MG Chemicals offers conductive paints with carbon, nickel, silver-coated-copper, and silver fillers. Carbon is cost-effective, suitable for RFI shielding and grounding. Silver has the highest conductivity and is excellent for high-frequency EMI shielding. Nickel and Silver-Coated Copper offer broad-range EMI/RFI shielding. The choice of binder impacts adhesion, durability, and chemical resistance, with MG offering options like solvent-based-acyclic, water-based, epoxy, and urethane systems.

Applications for conductive paint include EMI/RFI shielding, circuit prototyping, ESD protection, grounding, galvanic corrosion resistance, and electroplating on plastics.
