Abstract
A coating composition having outstanding electrically conductive and electromagnetic radiation absorptive properties is disclosed with a water emulsion polymer binder. The binder is a blend of a first emulsion containing a conjugated diene as monomer or comonomer, and a second emulsion containing an acrylic, aliphatic or aromatic polyurethane, polyester urethane, polyester, epoxy, polyamide, polyimide, vinyl, fluoropolymer, or silicone polymer. An effective amount of electrically conductive and electromagnetic radiation absorptive particles is dispersed in the binder. The particles include a combination of graphite particles, carbon nanotubes and metal containing particles. An effective amount of water is also present.
