  • Process for activating plastic surfaces for metallization thereof by treatment with a complex forming solution
    Patent number: 4298636
    Abstract: Plastic surfaces are activated for the reception of adherent metal coatings by depositing noble metal nuclei thereon, the noble metal nuclei being deposited by a multistep process including the steps of mechanically roughening the surface, treating the roughened surface with a complex-former solution, thereafter treating the surface with a solution of a noble metal complex salt so as to exchange the noble metal complex for the complex deposited by the initial complex-former solution, and converting the noble metal complex to form metal nuclei.
