Abstract
A sealant composition according to an embodiment includes, per 100 parts by mass of a solid rubber component containing a diene rubber, 95 to 150 parts by mass of a hydrocarbon resin, 20 to 100 parts by mass of a liquid plasticizer, and 0.05 to 1.5 parts by mass of sulfur. A crosslinked product of the sealant composition has a dynamic storage shear modulus G′ of 10 to 50 kPa as measured under the conditions of a temperature of 40° C., a frequency of 1.0 Hz, and a strain of 25%.
