  • Process for pretreating polyamide substrates for electroless metallization
    Patent number: 4554183
    Abstract: A mild activation process for the electroless metallization of polyamide mouldings comprises treating the mouldings with a solution of a mixture of halides of elements of the 1st and 2nd main group of the Periodic Table (for example CaCl.sub.2) with salts of weak inorganic bases and strong inorganic acids (for example AlCl.sub.3) in a swelling agent or solvent for polyamides and with a metal-organic complex compound of elements of the 1st or 8th sub-group of the Periodic Table. The sequence is here immaterial.
    Type: Grant

    Date of Patent: November 19, 1985
    Assignee: Bayer Aktiengesellschaft
    Inventors: Kirkor Sirinyan, Gerhard D. Wolf, Rudolf Merten, Ulrich von Gizycki
  • Surface metallized semiconductors
    Patent number: 4542074
    Abstract: The firmly adhesive metallization, in particular partial metallization, of the surface of semiconductors is possible, without pickling, by carrying out the activation with organometallic compounds of metals of the I and VIII Secondary Groups of the Periodic Table of Elements, then reducing in a conventional manner and metallization without current.

  • Black-metallized substrate surfaces
    Patent number: 4535032
    Abstract: Black-metallized substrate surfaces which are characterized by the fact that they reflect at most 20% of electromagnetic radiation within the wavelength range from 200 to 5,000 nm and at least 50% within the wavelength range from 7,000 to 24,000 nm, the percentages being relative to the mean value over the entire wavelength range in each case, and which can be used as sunlight collectors are obtained by metallizing activated substrate surfaces without current in metallizing baths which contain a polymeric surface-active compound.

    Date of Patent: August 13, 1985
    Assignee: Bayer Aktiengesellschaft
    Inventors: Kirkor Sirinyan, Rudolf Merten, Henning Giesecke
  • Metallized polymer granules, and their use
    Patent number: 4508780
    Abstract: Polymer granules having a single particle volume of 0.01 mm.sup.3 to 150 mm.sup.3 and a metal layer of 0.5 to 35% by weight, relative to polymer, can be processed by the customary methods of the plastics industry into shaped articles which have permanent antistatic properties and screen off electromagnetic waves.

  • Process for activating substrate surfaces for currentless metallization
    Patent number: 4493861
    Abstract: A simple and mild method of activating substrate surfaces for currentless metallization involves activating by means of organometallic compounds of elements of the 1st and 8th sub-Groups of the Periodic Table of Elements in which the organic moiety consists of oligomeric, prepolymeric or polymeric compounds containing double bonds.

  • Process for the production of metallized semiconductors
    Patent number: 4472458
    Abstract: The firmly adhesive metallization, in particular partial metallization, of the surface of semiconductors is possible, without pickling, by carrying out the activation with organometallic compounds of metals of the IB and VIIIB Groups of the Periodic Table of Elements, then reducing in a conventional manner and metallizing without current.
