A curable composition that includes (A) a silane compound copolymer that includes a specific repeating unit, (B) a silane coupling agent having a reactive cyclic ether structure, and (C) a curing agent so that the mass ratio “(A):((B)+(C))” of the silane compound copolymer (A) to the silane coupling agent (B) and the curing agent (C) in total is 95:5 to 70:30, a cured product obtained by curing the curable composition, and method for using of the curable composition as an optical device-securing adhesive or an optical device sealing material, are disclosed. The curable composition produces a cured product that does not show coloration (i.e., does not show a deterioration in transparency) even when exposed to high-energy light or subjected to a high temperature, exhibits excellent transparency for a long time, and has high adhesion even at a high temperature. The curable composition may be used to form an optical device-securing material, and may suitably be used as an optical device-securing adhesive or an optical device sealing material.
本发明公开了一种可治愈组合物,包括(A)一种包含特定重复单元的
硅烷化合物共聚物,(B)具有反应性环氧结构的
硅烷偶联剂和(C)固化剂,使得
硅烷化合物共聚物(A)与
硅烷偶联剂(B)和固化剂(C)的质量比“(A):((B)+(C))”总和为95:5至70:30。本发明还公开了通过固化可治愈组合物获得的固化产品,以及将可治愈组合物用作光学器件固定粘合剂或光学器件密封材料的方法。该可治愈组合物产生的固化产品即使暴露于高能光或高温下也不会出现着色(即不会出现透明度的恶化),长时间保持优异的透明度,并且即使在高温下也具有高粘附性。该可治愈组合物可用于形成光学器件固定材料,并可适当地用作光学器件固定粘合剂或光学器件密封材料。
