Conductive Paints

What is Conductive Paint?

Engineered by dispersing conductive pigments into resin binders, creating coatings that can conduct electricity across the painted surface. 

Conductive paints are lightweight and conformal – they can be sprayed, brushed, or dipped onto virtually any substrate, including plastics. This makes them ideal for retrofitting or shielding irregularly shaped components.

Applications

 

Pigment Options

MG Chemicals offers paints with graphite, carbon, nickel, silver-coated copper, and pure silver, providing options that tailor to both performance and budgetary requirements.

Graphite Conductive Paint – This economical anti-static material reduces low-frequency EMI/RFI. It cures to a smooth, durable finish and is resistant to abrasion, oxidation, and extreme thermal cycling – making it a great choice for outdoor treatments.

Carbon Conductive Paint – Excellent for grounding paint, electrical contact paint, or carbon shielding paint in low-frequency RFI shielding applications.

Nickel Conductive Paints – In addition to EMI/RFI shielding, nickel is also ferromagnetic and shields the magnetic component.

Silver-Coated Copper Conductive Paints – Highly conductive silver-coated copper flake creates a smooth, hard, and abrasion-resistant finish.

Silver Conductive Paints – Highest conductivity, and cures to a smooth, hard, and abrasion-resistant surface.

Resin Binder Options

Binding systems play a large role in determining the adhesion, durability, and chemical resistance of the coating. They also determine how the coating will be applied; properties like working time, application methods, and curing procedures.

Acrylic Conductive Paints – 1-part coatings that are easy to apply, cure quickly, and provide optimal EMI / RFI shielding to plastic electronic enclosures.

Epoxy Conductive Paints – 2-part coatings that offer superior adhesion, durability, and chemical resistance. They are suitable for use in harsh environments.

Water-Based Conductive Paints – 1-part coatings suitable for use on wood, and excellent for guitars and other instruments. They are also excellent on drywall and suitable for use on walls and other architectural applications.
