PURPOSE: A moisture-curable adhesive compostion is provided to keep initial adhesion through mechanical spreading without additional apparatus like dry chamber, cooling process, etc. CONSTITUTION: A moisture-curable adhesive compostion comprises 35-45 parts by weight of polyol, 55-65 parts by weight of 4,4'-diphenylmethane diisocyanate, a catalyst, and a co-catalyst. The moisture-curable adhesive composition comprises 0.005-1.0 weight% of benzoyl chloride or derivative thereof as a pot-life modifier on the basis of 100 weight% of the adhesive. The derivative of the benzoyl chloride is ortho-chlorobenzoyl chloride. The catalyst comprises 0.1-0.5 parts by weight of dibuthyltin dilaurate.
