PROBLEM TO BE SOLVED: To solve such a problem that when using a one pot type curable composition, containing an organic polymer having a reactive silicon group and a hollow particle composed of a thermally expandable microcapsule, filled in a container such as a cartridge, the composition oozes out from the tip of a nozzle when extrusion is halted.SOLUTION: A one pot type curable composition includes an organic polymer (A) having a reactive silicon group, and a hollow particle (B) obtained by expanding a thermally expandable microcapsule composed of an outer shell comprising a thermoplastic resin obtained by polymerizing a polymerizable component including a nitrile-based monomer and an expanding agent included in the outer shell and vaporizing by heating. The absolute specific gravity of the hollow particle is in a range of 0.025-0.100, the residue on ignition of the hollow particle is 20% or less, the average particle diameter of the hollow particle is in a range of 30 to 60 μm and a compound with a boiling point in a range of 20-40°C occupies 50 wt.% or more within the expanding agent. |
