摘要
Solvent-free moisture-curing polyurethane compositions are described, containing 99.9% to 75% by weight of at least one polyurethane prepolymer having free isocyanate groups, prepared by reaction of at least one polyol selected from the group of the polyether polyols and polyester polyols, having at least one polyisocyanate in stoichiometric excess, at least one polyol being a recycled polyethylene terephthalate polyol. In addition, this composition contains 0.1% to 25% by weight of at least one additive selected from the group of the catalysts, resins, plasticizers, fillers, pigments, stabilizers, adhesion promoters and further polymers. The sum total of the aforementioned constituents is 100% by weight. These compositions can be used as a one-component adhesive, reactive hotmelt adhesive, coating material or sealant.
