(57) [Summary] [PROBLEMS] To provide a modified polysulfide-based sealant composition which has a low viscosity, good workability, excellent thixotropy and does not cause slump at all. [Structure] 1 to 1 parts by weight of (a) modified polysulfide polymer, (b) curing catalyst, and (c) surfactant. 0 parts by weight and (d) SiO 2 alone or SiO 2 and Al 2 It is characterized by containing 1 to 10 parts by weight of a mixture of O 3 . |
