Polyurethane resin composition and sealed article

Abstract

Polyurethane resin compositions are used to seal objects such as electrical and electronic components in order to provide protection from condensation and contamination. Such polyurethane resin compositions are often used in high-temperature environments. Thus, a polyurethane resin composition having high heat resistance is provided. The polyurethane resin composition is obtained by reacting a hydroxyl-group-containing compound (A) with an isocyanate-group-containing compound (B) and contains an antioxidant (C) having an alkylthio group.
