Title:
TWO-PACK TYPE CURABLE POLYURETHANE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/203904
Kind Code:
A1
Abstract:
The present invention achieves both wet heat resistance and tensile elongation.　A two-pack type curable polyurethane resin composition according to an embodiment comprises a first component, which comprises polyols and a terpene resin, and a second component, which comprises a polyisocyanate. The polyols include 40 mass% or more polybutadiene polyol and/or hydrogenated polybutadiene polyol and further include 5-40 mass% (meth)acrylic polyol. The content of the terpene resin is 3-60 parts by mass per 100 parts by mass of the polyols.
