A room temperature hardenable composition having a reactive silicon group that without detriment to the recoverability, durability and creep resistance of hardened matter, can have its mechanical properties regulated to those suitable for sealing materials and adhesives and that has a low viscosity ensuring high workability. There is provided, for example, a hardenable composition comprising organic polymer (A) having a reactive silicon group, represented by the following general formula (1) wherein a is 3 and organic polymer (B) having an average of 0.5 to 1.5 reactive silicon groups per molecule, represented by the following general formula. -Si(R<1>3-a)Xa (1). |
