Title: AQUEOUS ADHESIVE COMPOSITION BASED ON EPOXY RESIN WITH IMPROVED ADHESION AND STORAGE STABILITY
Abstract:
The invention relates to an aqueous adhesion composition comprising: a) at least one dispersed solid epoxy resin (EP); b) at least one amino silane (AS); c) at least one acid (HS); d) at least one amine hardener (AH); and e) water. According to the invention, the adhesion compositions substantially improve, particularly under humid conditions, the adhesion on different substrates. The compositions are storage stable for a longer period of time and have, even after different aging states of the components, essentially no impairment in the action thereof.
