Abstract

The invention relates to a crosslinkable one-component lamination adhesive containing a) 25 to 80 wt % of polyester prepolymers, polyether prepolymers, and/or polyurethane prepolymers that comprise at least two crosslinkable silane groups, b) 75 to 20 wt % organic solvent having a boiling point of up to 130° C., c) 0 to 15 wt % additives, the prepolymer having a molecular weight from 2000 to 30,000 g/mol, wherein the viscosity of the adhesive is between 50 and 20,000 mPas (per DIN ISO 2555) measured at 15 to 45° C., and the crosslinked adhesive has a glass transition temperature from −10 to 30° C.
