Title:
TWO-COMPONENT CURABLE POLYURETHANE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2024/057899
Kind Code:
A1
Abstract:
The present invention achieves both adhesiveness and storage modulus at high temperatures. A two-component curable polyurethane resin composition according to an embodiment comprises: a first component including a polyol and a terpene resin; and a second component including a polyisocyanate. The polyol contains at least 40 mass% of a polybutadiene polyol and/or a hydrogenated polybutadiene polyol, and contains 3-15 mass% of a polyether polyol obtained by adding an alkylene oxide containing at least 40 mol% of a propylene oxide and/or a butylene oxide to an active hydrogen-containing compound having 3-6 functional groups. The content of the terpene resin is 3-60 parts by mass with respect to 100 parts by mass of the polyol.
