Claim:
1. An isocyanate-free multicomponent system comprising at least two separate components, the first component comprising at least one alkoxysilane-terminated prepolymer and the second component comprising an aqueous component, with the aqueous component comprising a polyurethane dispersion comprising 5 to 65 wt % of polyurethane based on the total weight of the polyurethane dispersion, wherein the alkoxysilane-terminated prepolymer comprises an alkoxysilane-terminated polyurethane prepolymer and an isocyanate-terminated prepolymer, wherein the alkoxysilane-terminated polyurethane prepolymer is prepared from an [(cyclohexylamino)methyl]triethoxysilane and an isocyanate-terminated prepolymer, and wherein the isocyanate-terminated prepolymer is prepared from a polyol and an aliphatic polyisocyanate, wherein the first and the second component of the multicomponent system are present in a volume ratio of 2:1 to 3:1 to one another.
