Abstract
A moisture-curable hot-melt adhesive composition is disclosed. This moisture-curable hot-melt adhesive composition contains: a urethane prepolymer including a polymer chain, which includes a structural unit derived from a polyol and a structural unit derived from a polyisocyanate, and having two or more isocyanate groups; and a modified urethane prepolymer including a polymer chain, which includes a structural unit derived from a polyol and a structural unit derived from a polyisocyanate, and having one or more isocyanate groups modified with a castor oil monool.
Claims12
A moisture-curable hot-melt adhesive composition comprising:
- a modified urethane prepolymer including a polymer chain, which includes a structural unit derived from a polyol and a structural unit derived from a polyisocyanate, and having one or more isocyanate groups modified with a castor oil monool;
- and
- a urethane prepolymer, different than the modified urethane prepolymer, including a polymer chain, which includes a structural unit derived from a polyol and a structural unit derived from a polyisocyanate, having two or more isocyanate groups, and not having an isocyanate group modified with a castor oil monool.
