Abstract: The invention relates to an extensively biologically degradable adhesive tape, which in particular has a good and quickly established anchoring between the adhesive and the carrier. The invention relates to an adhesive tape for protecting surfaces, comprising an adhesive H, containing at least 60 wt %, at least one polyurethane P, obtainable from chemical cross-linking of a polyurethane pre-polymer, obtainable from the chemical reaction of d) one or a plurality of aliphatic polyester polyols A having a hydroxy functionality of 1.8 through 2 and a number-averaged molecular weight of equal to/greater than 1,000 g/mole; e) one or a plurality of compounds B having a hydroxy functionality of 1.8 through 2 and a number-averaged molecular weight of less than 1,000 g/mol; f) one or a plurality of aliphatic diisocyanates C; wherein the ratio of the total number of isocyanate groups to the total number of hydroxy groups of the substances involved in the chemical reaction for building the prepolymer is greater than/equal to 0.4 and less than 1; and a biodegradable carrier.

Abstract: A biodegradable pressure-sensitive adhesive is provided, having good shear strength at relatively high temperatures. This is achieved by chemical crosslinking of a polyurethane prepolymer obtainable by chemical reaction of a) one or more aliphatic polyester polyols A having a hydroxyl functionality of 1.8 up to and including 2 and a number-average molecular weight of greater than/equal to 1000 g/mol; b) one or more compounds B having a hydroxyl functionality of 1.8 up to and including 2 and a molecular weight of less than 1000 g/mol; and c) one or more aliphatic diisocyanates C, where the ratio of the total number of isocyanate groups to the total number of hydroxyl groups in the substances involved in the chemical reaction is greater than/equal to 0.4 and less than 1; and by the formulation of a pressure-sensitive adhesive having one or more polyurethane(s) of this kind as the main constituent.
