Abstract: A chrome-free acidic aqueous solution of sulfuric acid and one or more organic acids and manganese (II) and (III) ions is applied to an organic polymer surface to etch the surface. The etched surface is then plated with metal.

Abstract: An electroless nickel plating liquid capable of forming an underbarrier metal for metal bumps or solder bumps by electroless nickel plating with a uniform film thickness on silicon wafers composed of multiple IC chips contains a water-soluble nickel salt, a reducing agent, a complexing agent, and a pH buffer, wherein_lead ion is contained at 0.01-1 ppm, cobalt ion is contained at 0.01-1 ppm, and a sulfur compound is contained at 0.01-1 ppm.

Abstract: The quality of painted surfaces of polymeric articles is improved by depositing a coating of a metal such as zinc or zinc alloy on the surface of the article to be painted. For example, zinc is electrodeposited on a conductive surface of the article. The metal coated polymeric surface provides a good base for electrostatic deposition of either liquid or powder paint and the metal surface prevents the formation of defects in the painted surface during heating of the article to dry or cure the paint film.

Abstract: The quality of painted surfaces of polymer composites is improved by first forming an electroless metal coating on the molded surface of the composite and then electroplating a coating of zinc or zinc alloy on the metallized composite surface. The “galvanized” composite surface provides a good base for electrostatic deposition of either liquid or powder paint and the zinc surface prevents the formation of defects in the painted surface during heating of the composite to dry or cure the paint film.

Abstract: A plated molded article which comprises a molded article formed with a resin composition comprising specific relative amounts of (A) a styrenic polymer having a syndiotactic configuration and (B) at least one selected from the group consisting of (a) rubbery elastomers soluble in an oxidizing agent, (b) thermoplastic resins soluble in an oxidizing agent, and (c) inorganic compounds soluble in an oxidizing agent, and has been plated; and a process for producing the plated molded article. A plated molded article containing a styrenic polymer having a syndiotactic configuration which suppresses skipped plating and has a high adhesive strength of the plating film can efficiently be obtained with stability in an industrial process.

Abstract: A process for metal plating a high impact, high temperature plastic suitable for forming trim elements of an automobile. The process is particularly directed to plating an elastomer-modified PPA resin, and entails closely controlled process steps that include selectively etching the elastomer and the PPA matrix with a solution containing chromic acid, then effectively removing from the substrate any retained chromium which would adversely affect the ability of metal plating to adhere to the substrate, and thereafter protecting the substrate from attack by sulfuric acid. The process is particularly effective for electroplating a PPA resin modified with about five to about 30 weight percent EPDM.

Abstract: A polymer substrate is plated with a metal, using metallic filler particles in the polymer as anchorage points for a layer of metal formed by an electroless plating operation. The polymer has a filler that includes non-metallic filler particles and metallic filler particles; the non-metallic filler particles contiguous to the polymer surface can be etched away, so as to expose metallic filler particles proximate to the etched surfaces. The exposed metallic filler particles serve as anchorage points for the electroless plate layer.
