  • Coated abrasive tools from non-blocked urethane prepolymer
    Patent number: 7811342
    Abstract: A polyurethane adhesive composition, formed by combining a non-blocked urethane prepolymer and a polymeric polyol, is used for preparing a coated abrasive tool. The polyurethane adhesive composition is applied over a substrate to thereby form a polyurethane-adhesive-composition-coated substrate. Curing the polyurethane-adhesive-composition-coated substrate forms a polyurethane-adhesive-coated substrate. An abrasive material is applied over the substrate at a time selected from the group consisting of prior to, after, and simultaneously with, the application of the polyurethane adhesive composition to the substrate, to thereby form the coated abrasive tool. The coated abrasive tool preferably includes a polyurethane adhesive resin coating over the substrate, the resin coating being formed from a polymerization reaction of a non-blocked urethane prepolymer and a phenoxy resin.
