MOISTURE-CURING POLYURETHANE COMPOSITION COMPRISING RENEWABLE RAW MATERIALS

摘要

99.9% to 75% by weight of at least one polyol selected from the group of polyether polyols and polyester polyols, wherein at least one polyol which is a recycled polyethylene terephthalate polyol is reacted with a stoichiometric excess of at least one polyisocyanate , And at least one polyurethane prepolymer having a free isocyanate group are described. The composition also contains from 0.1% to 25% by weight of at least one additive selected from the group of catalysts, resins, plasticizers, fillers, pigments, stabilizers, adhesion promoters and further polymers. The total sum of the above-mentioned components is 100% by weight. These compositions can be used as one-component adhesives, reactive hot-melt adhesives, coating materials or sealants.
