Patent - This invention describes a one- or two-component adhesive containing: a) a binding agent having reactive isocyanate groups or silane groups, and b) a nonreactive polymer having a glass transition temperature (measured by means of DSC) in the range from −40° C to +60° C. This preferably has, in a cured state, at a temperature at least in the range from −10° to +50° C., a dynamic mechanical loss factor tan δ of at least 0.4 at a frequency in the range from 10 to 400 Hz. Use of an adhesive of this kind is common for the adhesive bonding of components in the manufacture or repair of vehicles, in particular for bonding windows into place in the context of direct glass bonding.
