Abstract
The present invention is to provide a composition which can easily form a polyurethane resin which exerts particularly excellent damping properties in an operating temperature range. A resin composition for damping materials, including a polyol-containing component (A) and a polyisocyanate (B) is provided. The polyol-containing component (A) contains a castor oil. When the composition is cured, the peak on its Tan δ curve is 0.7 or more and the temperature for the peak is in a range of −10° C. to 100° C.
