| 摘要 |
The present invention discloses a moisture-curable hot-melt adhesive agent which comprises an alicyclic urethane prepolymer having isocyanate groups respectively at terminals of the alicyclic urethane prepolymer, wherein the alicyclic urethane prepolymer has a chemical structure derived from a polycarbonate polyol and at least one of the isocyanate groups located at the terminals is bound to a chemical structure derived from an aromatic ring. The adhesive agent has excellent adhesion properties (initial adhesiveness and adhesiveness after curing), light resistance (light-resistant adhesion force, yellow discoloring properties, color-fading properties, etc.) and curability (heat resistance). |
