Abstract:
Disclosed is a polyisocyanate composition which is excellent in both curability and drying characteristic. The polyisocyanate composition contains at least one compound selected from aliphatic diisocyanates, at least one compound selected from alicyclic diisocyanates and at least one compound selected from polyols, while satisfying all of the following conditions; i) the diisocyanate monomer concentration is not more than 3 mass %, ii) the polyol component concentration is 1-50 mass %; and iii) the glass transition temperature is from −50° C. to 0° C.
