ANTISTATIC POLYURETHANE ADHESIVE AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an antistatic polyurethane adhesive which has a good re-releasability, is excellent in followability to surface unevenness of an adherend and produces little electrostatic charge at peeling. SOLUTION: The antistatic polyurethane adhesive is obtained by hardening a composition including at least (A) a polyurethane containing a hydroxyl group, (B) an ionic compound and (C) an isocyanate hardener containing a trifunctional isocyanate compound (C1) of a biuret type.
