AQUEOUS ADHESION PROMOTER COMPOSITION COMPRISING AN AMINOSILANE AND A MERCAPTOSILANE

摘要

The present invention relates to aqueous adhesion promoter compositions which comprise at least one aminosilane and/or aminosiloxane and also at least one mercaptosilane. The adhesion promoter compositions are suitable more particularly as primers or adhesion-promoter undercoats for adhesives and sealants. They are especially suitable for the adhesive bonding of vehicle glazing. Exceptionally high adhesion has been found more particularly with glazing featuring applied silver prints.
