An object of the present invention is to provide a curable composition excellent in on-site formability, excellent in heat resistance, chemical resistance and oil resistance, and low in compression set. The invention relates to a curable composition comprising (a) a vinyl-based polymer containing at least one (meth)acryloyl group in a molecule thereof and having a number average molecular weight of 500 to 1,000,000, (b) an ethylenic unsaturated group-containing compound, (c) a thixotropic property-imparting agent, (d) fumed silica surface-treated with a (meth)acryloyl group-containing silane and (e) a photopolymerization initiator.
本发明的目的是提供一种现场成型性优异、耐热性、耐化学性和耐油性优异、压缩永久变形小的可固化组合物。本发明涉及一种可固化组合物,该组合物包括:(a) 乙烯基聚合物,其分子中至少含有一个(甲基)丙烯酰基,且其平均分子量在 500-1,000,000 之间;(b) 含乙烯基不饱和基团的化合物;(c) 触变性引发剂;(d) 经含(甲基)丙烯酰基硅烷表面处理的气相二氧化硅;(e) 光聚合引发剂。
