Herein we prepared an adhesive for laminated electrical steels that has excellent adhesion and oil resistance for dot-bonded motor core for electric vehicles. Its outstanding adhesion and oil resistance originate from isosorbide core structure having good hydrophilicity and a rigid chemical structure. The adhesion property was evaluated by measuring the lap shear strength of the laminated electrical steel and peel strength of the dot-bonded motor core and compared it to an adhesive to which petroleum-based alicyclic polyol was applied. Isosorbide derivative was incorporated in acrylate modified polyurethane as a polyol for compatibility with other adhesive components and to enact a fast-curing process.
