Abstract (en)
This invention concerns resistor compositions, methods of forming such resistor compositions, and articles comprising a substrate carrying such resistor compositions. The resistor compositions of the invention comprise carbon particles embedded in a matrix formed from short chain-length phenolic resin, long chain-length phenolic resin, epoxy and, optionally filler. The resistor compositions of the invention can be formed by mixing short chain-length phenolic resin, long chain-length phenolic resin, solvent, and, if present, filler with carbon particles to form a solution which is then mixed with the epoxy to form an ink. The ink is applied to a substrate to form a film thereon which is cured to evaporate solvent and to allow polymerization to occur thereby leaving the resistor composition on the substrate.
