NEUTRAL-COLOURED 1K POLYURETHANE ADHESIVE

摘要

The invention relates to a polyurethane prepolymer, which can be produced fr om at least one polyisocyanate that is symmetrically substituted in terms of it s NCO groups, at least one polyisocyanate that is asymmetrically substituted i n terms of its NCO groups, at least one polyol with an OH functionality of mor e than 2.5 and at least one polyol with an OH functionality of less than 2.5. The invention also relates to a method for producing a polyurethane prepolym er of this type, to an adhesive containing at least one polyurethane prepolymer of this type and to the use thereof.
