  • Patent number: 10161044
    Abstract: A polymer product with a metal layer coated on the surface thereof is provided. The polymer product includes a polymer substrate and a metal layer formed on at least a part of a surface of the polymer substrate. The surface of the polymer substrate covered by the metal layer is formed by a polymer composition comprising a polymer and a doped tin oxide. A doping element of the doped tin oxide comprises niobium. The doped tin oxide has a coordinate L* value of about 70 to about 100, a coordinate a value of about ?5 to about 5, and a coordinate b value of about ?5 to about 5 in a CIELab color space.

  • Publication number: 20170211186
    Abstract: A metalized plastic article and a method for selectively metallizing a surface of a plastic substrate are provide. The metalized plastic article includes a plastic substrate and a metal plating layer formed on the surface of the plastic substrate. At least a surface layer of the plastic substrate covered by the metal plating layer is formed by a plastic composition. The plastic composition includes a base resin and a doped tin oxide. A doping element of the doped tin oxide is at least one selected from a group consisting of cerium, lanthanum, fluorine and tantalum. The metalized plastic article of the present disclosure has a good light absorption performance and a high chemical plating activity.

  • Publication number: 20170175271
    Abstract: Provided is a doped tin oxide that can be used as a chemical plating promoter in a method for selectively metallizing a surface of an insulating substrate. Also provided are a polymer composition that includes the doped tin oxide, a polymer molded body, an ink composition, and a method for selectively metallizing a surface of an insulating substrate. The doped tin oxide has a light color, and does not interfere with the color of the substrate while presetting thereof. The doped tin oxide has a strong ability of promoting chemical plating. Using the disclosed doped tin oxide as a chemical plating promoter, a continuous metal layer can be formed with a high plating speed, together with enhanced adhesivity between the metal layer and the insulating substrate.
