摘要： PROBLEM TO BE SOLVED: To provide a resin composition having good handleability in dispenser application and enabling proper coating with a small application amount of the composition.
SOLUTION: The resin composition contains ≥40 vol.% of a thermosetting resin which exists in liquid state at normal temperature, and 5-30 vol.% of a wax component which exists in powdery state at normal temperature and has a melting point of 70-150°C. The viscosity of the resin composition is 50,000-150,000 mPa s at normal temperature. Since the resin composition keeps a proper viscosity in dispenser application, it has high handleability. The composition decreases the viscosity in heat-setting to increase fluidity and forms a state having good wettability, and, accordingly, proper coating can be achieved even in the case of small application amount or few injection points.
