Abstract

The invention relates to a polyurethane composition with the properties of a pressure-sensitive adhesive, to a method for its production and to its use as pressure-sensitive adhesive. The aim of the invention is to provide an optimized adhesive that has good adhesive properties even when the adhesive link has been repeatedly released and joined again and with a reduced migration of noxious components. To this end, the invention provides a polyurethane composition that is obtained by reacting two components A and B, wherein a) at least one polyurethane prepolymer A1 is used as component the A, said prepolymer having been obtained by reacting at least one polyol component with at least two bifunctional different isocyanates, and b) at least one bifunctional hardener as the component B, said hardener having per molecule at least two functional groups that are reactive to isocyanate groups. The ratio of isocyanate groups to functional groups that are reactive to isocyanate groups should be greater than 0.75 and lower than 1.15.
