The present invention relates to aqueous-based primer composition, comprising at least one thermosetting, self-emulsifying epoxy resin composition; at least one thermosetting, non-self-emulsifying resin composition; water; and at least one curative.

Primer compositions for adhesive bonding systems and coatings

The present invention relates to an acidic aqueous particulate composition containing, in addition to iron(III) ions, fluoride ions and at least one water-insoluble, dispersed organic binder, a water-insoluble, dispersed oxide pigment with elevated resistance to agglomeration for the autophoretic deposition of organic-inorganic hybrid layers onto metal surfaces, the composition additionally containing at least one anionic wetting agent which comprises functional groups selected from sulfonates, phosphonates and/or carboxylates. The invention furthermore comprises the use of such a composition for the autodeposition of a film-forming organic-inorganic hybrid coating onto metal surfaces which are at least in part selected from surfaces, the main constituents of which are iron, zinc and/or aluminum.

Anionic wetting agents for stabilizing self-depositing compositions comprising oxidic pigments

The present invention relates to initiators of the general formula {[M(L)]X}, wherein said initiators preferably have (SbF) as a counterion and are obtainable by a complexing reaction of a corresponding metal-SbFsalt with a corresponding ligand (L). The present invention further relates to preparations and epoxy resin systems that contain such initiators and, in particular, are non-thermally and/or thermally curable.
