は易くなり、モジュラスの低下を生じる。The sealant composition of the present invention contains the superhydrophobic silica at 0.1 parts by weight per 100 parts by weight of the polysulfide polymer.
It contained ~3.0 parts by weight, which improved the storage stability when uncured, resulting in properties with excellent workability, and the cured product was less susceptible to a decrease in modulus due to moisture. Note that if the superhydrophobic silica is less than 0.1 part by weight, the properties of the sealant composition will become too soft, resulting in poor workability. In addition, the sealant, which is a cured product of the sealant composition, becomes susceptible to moisture, resulting in a decrease in modulus.
