Solids-free pretreatment solution for electrically non-conductive surfaces as well as a method for the production of the solution and their use

摘要

the invention relates to a solution for vorbehandeln electrically nichtleitender surfaces and a method for coating the surface with particles, such as carbon black, graphite, silica, aluminium oxides, the u00fcbergangsmetallchalcogenide and titanium dioxide. the invention also relates to a process for the solution.$a solution is used to vorbehandeln electrically nichtleitender surfaces, preferably the vorbehandeln of polymers.it contains a solvent, preferably water, and at least one polyelektrolytverbindung as koagulationsauslu00f6ser and, in addition, at least compared to the polyelektrolytverbindung opposite charged surfactant by the charge of the polyelektrolytverbindung at least teilwe ise compensated or overcompensated.$a, the surfaces are treated according to the following procedure: (a) $a treating surfaces with the vorbehandlungslu00f6sung; $a (b) coating the particles in contact with the surface of a dispersion containing the particulate material, a dispersion against koagula and the particles stabilizing second surfactant and a dispersion destabilizing salt.
