PURPOSE: Provided is an one-part polyurethane resin composition which has improved workability as a top coat and a prime coat and storage stability, and has excellent hardness and chemical resistance once it is cured. CONSTITUTION: The one-part polyurethane resin composition is characterized by comprising 20 to 50 wt% of a hard segment polyurethane resin and 50 to 80 wt% of a soft segment polyurethane resin. In particular, the hard segment polyurethane resin can accelerate initial drying to shorten the time needed for repainting, and the soft segment polyurethane resin can facilitate the roller and spray working and can be served as a coating agent. |
