USE OF CARBOLIC ACID HYDRIDE FOR DEBONDING POLYURETHANE ADHESIVES

摘要

The present invention relates to the use of carbolic acid hydrides for debonding polyurethane adhesives. The carbolic acid hydride is present in the polyurethane adhesive as a solid, thus not integrated in the polymer. When the adhesive is heated to a temperature of at least 80°C, the polymer is thermally broken down. Such an adhesive has the advantage that components thereby adhered can be released in a simple method, wherein the repair, reclamation, or recycling of the components is made easier.
