Abstract:

A curable composition comprising a polymer having two or more thiol groups per molecule, a compound having two or more isocyanate groups per molecule, and carbon black and further containing a filler consisting mainly of silicic acid or a silicate or an organic filler consisting mainly of pulverized coal. The main ingredient has satisfactory storage stability. Even after storage of the main ingredient, the composition has satisfactory curability and gives a cured article having sufficient breaking strength, hardness, and gas-barrier properties. The curable composition is hence suitable for use as a sealing material for double glazings, vehicle window frames, etc. The curable composition preferably further contains a hydrocarbon plasticizer and an organometallic compound. This composition is a high-performance curable composition which attains even higher mechanical strength and gas-barrier properties.
