ABSTRACT:
The invention relates to a process for the continuous chemical metallizing of porous substrates in a wet-chemical manner. According to the invention, the different reaction rates of the adsorption or ionic reduction reaction, in the case of activating with Pd/Sn, are adapted to the chemical metallizing reaction used. The removal of the spent process solutions from the pores of the substrate takes place by suction. The invention permits a continuous implementation of the process of depositing a metal layer on an electrically non-conductive, synthetic substrate, which can be used at the start of a galvanic reinforcing process of the chemically deposited metal coating.
