摘要

An abrasive work piece (1) comprises an abrasive material (2) that is bonded to a substrate (4) by means of an adhesive (3). The adhesive (3) is a polyurethane having a viscosity (Brookfield, 20 [deg]C, DIN 53019) of at least 750,000 mPas and is applied to the abrasive material and/or the substrate. An independent claim is included for a process for the manufacture of the abrasive work piece (1) by application of the polyurethane based adhesive (3) onto the substrate followed by bonding the abrasive material onto the substrate.
