(57) [Problem] To provide a one-part moisture-curable polyisocyanate composition having excellent weather resistance, a long pot life, and a rapid curing reaction. SOLUTION: A polyisocyanate prepolymer obtained by reacting a polyether polyol and / or polyester polyol having a number average molecular weight of 300 to 8000 with an excess amount of an aliphatic and / or alicyclic diisocyanate or a polyisocyanate having these as a basic skeleton. Polymer and polyisocyanate prepolymer at 0.0 A one-component moisture-curable polyisocyanate composition obtained by mixing 0.5 to 2% by weight of a moisture-curing acceleration catalyst, for example, dibutyltin dilaurate. |
