Abstract:
A curable polyurethane type resin composition which is applicable for a sealing material for an electrical device used in a vehicle, enhances a hydrolysis resistance of a cured substance and can suppress a decrease in physical properties in high temperature and high moisture environments. The curable polyurethane type resin composition contains castor oil-type polyol, polyisocyanate, and epoxidized acrylic polymer. The electrical device has electrical components covered with a sealing material consisting of a cured substance of the curable polyurethane-type resin composition.
