Document Type and Number:
WIPO Patent Application WO/2017/188050
Kind Code:
A1
Abstract:
Provided are: a curable polyurethane-based resin composition which is applicable to an encapsulating material for electrical components to be mounted on vehicles and can give cured objects that have improved hydrolytic resistance and are inhibited from deteriorating in physical property in high-temperature high-humidity environments; and an electrical component obtained using the curable polyurethane-based resin composition. The curable polyurethane-based resin composition comprises a castor-oil-based polyol, a polyisocyanate, and an epoxidized acrylic polymer. The electrical component (1) comprises an encapsulating material (2) constituted of a cured object of the curable polyurethane-based resin composition and an electronic component (3) covered with the encapsulating material (2).
