  • Patent number: 4113899
    Abstract: Electroless nickel coating of epoxy resin foundry patterns and core boxes can be carried out without a palladium chloride/stannous chloride activation of the surface, if the pattern or core box contains a high density of metal particles which act as "keying" sites, and if the metal-filled resin surface is properly prepared. The preparation steps include a very light abrading with a fine (minus 60 U.S. mesh and preferably even finer) grit and a very brief acid pickling step. The electroless-plated article has a continuous coating of nickel bonded essentially directly to the resin through the metallic "keying" sites.
