    • 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.
    • 一种可固化组合物,其包含每分子具有两个或更多个硫醇基的聚合物,每分子具有两个或多个异氰酸酯基的化合物和炭黑,并且还含有主要由硅酸或硅酸盐或主要由粉碎的 煤炭。 主要成分具有令人满意的储存稳定性。 即使在保存主要成分之后,组合物也具有令人满意的固化性,并且具有足够的断裂强度,硬度和阻气性的固化制品。 因此,固化性组合物适合用作双层玻璃,车窗框等的密封材料。固化性组合物优选还含有烃增塑剂和有机金属化合物。 该组合物是能够获得更高的机械强度和气体阻隔性的高性能可固化组合物。
