Multi-component aqueous primer compositions (APC) comprising a component (K1) containing water and epoxy resin(s) (A), a component (K2) containing polyamine(s) (B) and if necessary other component(s), in which the APC contains carbon black, epoxysilane(s) (ES), epoxysiloxane(s) (ESx), amino-silane(s) (AS), aminosiloxane(s) (Asx) and/or mercaptosilane(s) (MS), with the proviso that, if ES and/or ESx is present, it is not in the same component as any AS and/or ASx. Independent claims are also included for (1) an adhesive bonding or sealing method involving making APC as above, applying it to a substrate (S1), drying in air, applying an adhesive or sealant and contacting with a second substrate (S2), or by carrying out the same process but applying the adhesive or sealant to S2 instead of S1, or by applying the adhesive or sealant between S1 and S2 (which may consist of the same or different materials) (2) articles manufactured by a process involving this method. |
