More Information
Summary:A conductive composition capable of producing a conductive coating with excellent flexibility and a high conductivity comparable to that of metallic silver, without using high temperatures as film forming conditions. The conductive composition includes a particulate silver compound and a binder, and optionally a reducing agent and a binder. Silver oxide, silver carbonate and silver acetate and the like are used as the particulate silver compound. Ethylene glycol, diethylene glycol, and ethylene glycol diacetate and the like are used as the reducing agent, and a fine powder of a thermosetting resin such as a polyvalent phenol compound, phenol resin, alkyd resin or polyester resin, or a thermoplastic resin such as a styrene resin or polyethylene terephthalate, with an average particle diameter from 20 nm to 5 μm is used as the binder. Furthermore, the average particle diameter of the particulate silver compound may be from 0.01 to 10 μm.
