Abstract: Embodiments of the present invention provide an adhesive requiring a low modulus of elasticity and a liquid epoxy resin composition that is used for the adhesive thereof. The liquid epoxy resin composition not only exhibits flexibility or a low modulus of elasticity to prevent magnet cracking in the manufacturing of a rotor, using a ferrite magnet in particular, but also does not undergo a decrease in weight while exhibits minimal dimensional change. This is true even if the liquid epoxy resin is immersed in an automatic transmission fluid, for a long period of time, in an environment which is used as a rotor. The liquid epoxy resin composition according to the embodiments of the present invention includes a bisphenol A type epoxy resin, an epoxy resin containing a polyoxyalkylene structure, and a curing agent as essential components, used for the adhesive.

Abstract translation: 本发明的实施方案提供了一种需要低弹性模量的粘合剂和用于其粘合剂的液体环氧树脂组合物。 液体环氧树脂组合物不仅具有柔软性或低弹性模量，以防止制造转子时的磁体破裂，特别是使用铁氧体磁体，而且在显示最小的尺寸变化的同时也不会发生重量的减轻。 即使液体环氧树脂在用作转子的环境中长时间浸入自动变速器油中也是如此。 根据本发明实施方案的液体环氧树脂组合物包含双酚A型环氧树脂，含有聚氧化烯结构的环氧树脂和用作粘合剂的必要组分的固化剂。

Abstract: Provided are a UV curable composition which can be cured without undergoing a high-temperature heating step and has excellent adhesiveness and mechanical strength; and a sheet using the same. This UV curable composition includes a rubber component having a diene skeleton, a photopolymerization initiator, and a cross-linking agent, wherein the rubber component having a diene skeleton contains a solid rubber component and a liquid rubber component at 25° C. The UV curable composition can be cured by UV irradiation in a short time, and can thus be applied to not only an adherend having high heat resistance but also a wide range of members.

Abstract: Provided is a black light-shielding member, which has an excellent effect of anti-reflection that based on low glossiness and has a high blackness. A black light-shielding member including a substrate film, a resin-made light-shielding layer having a concave-convex shape formed on at least one surface of the substrate film, and a blackened layer formed on the resin-made light-shielding layer is produced. By adjusting an arithmetic mean surface roughness Ra of the surface on which the light-shielding layer and the blackened layer are formed to be 0.25 μm or more, and the maximum thickness of the blackened layer is less than the said Ra, a blackness with an L value of 12 or less is achieved.

Abstract: The present invention is a method that enables continuous injection molding of a thermosetting resin composition and reuse of an unnecessary part produced during the molding. The method includes injecting a thermosetting resin composition into a mold while a curing reaction of the resin composition is incomplete. The thermosetting resin composition is then cooled in the mold until becoming semi-cured and removed as a semi-cured product from the mold. The semi-cured product is separated from the unnecessary part and separately heated to progress a thermosetting reaction of the thermosetting resin composition. The unnecessary part may be used as a reworked raw material by regrinding the unnecessary part and mixing it with a fresh thermosetting resin composition. Then, a resultant mixture is used to perform a new injection molding.
