Title:

TWO-COMPONENT CURABLE POLYURETHANE RESIN COMPOSITION

Document Type and Number:

WIPO Patent Application WO/2023/136064

Kind Code:

A1

Abstract:

The purpose of the present invention is to improve tensile properties. A two-component curable polyurethane resin composition according to one embodiment contains: a first component that contains a polyol and a terpene resin; and a second component that contains a polyisocyanate. The polyol contains 40 mass% or more of a polybutadiene polyol and/or a hydrogenated polybutadiene polyol, and also contains 4-15 mass% of an alkylene polyol having 7-9 carbon atoms. The content of the terpene resin is 5-60 parts by mass relative to 100 parts by mass of the polyol.
