| A General Guide For Applying Conductive Paints
Spraylat's conductive paint products incorporate selected alternative metallic media that offer a range of coating performance characteristics which can satisfy a variety of product applications. These high solids paints are formulated to provide a uniform, high quality conductive film when sprayed. Individual products vary in several ways. These variations influence both their application and coating performance.
- Type of Metallic Media
- Diluent: Solvent or Water
- Solids Content
- Resin System
Today, there are three commercially important types of media used for EMC applications: copper (silver-coated copper); pure silver; and hybrid (mixture of silver and copper).

Each type of conductive paint is available in either water-based or solvent-based formulations. Solvent-based paints will vary in their product application characteristics depending upon the individual product formulation. The latest generation of solvent-based products, known as SOS (Safe-On-Substrate), is formulated using an alcohol rather than a stronger solvent like MEK (methyl ethyl ketone). Also available are water-based products known as Neptune.
Each product formulation has its own application characteristics. For example, copper paints will have different production spray application characteristics than silver paints. This is due, in part, to the larger particle size of the copper conductive media as compared to the smaller silver particles. Water-based paints will atomize differently than solvent-based paints and require different gun settings and application techniques.
