Abstract
An electrically conductive lacquer adapted for use in heating elements is prepared by dispersing electrically conductive particles in an aqueous plastic dispersion in an aqueous silicate solution. Sodium or potassium silicate and an acrylic resin may be used in making the dispersion. The electrically conductive particles may be carbon or particles having a noble metal surface.
Claims2
An electrically conductive lacquer consisting essentially of silver-plated copper particles, acetylene soot particles, and a binder, the binder being an aqueous dispersion of a copolymer of butyl acrylate, vinyl acetate, and acrylic acid in an aqueous silicate solution.
