Curable compositions are widely used as paints, adhesives, sealants, insulating materials, molding materials, etc., and many are known, including epoxy resins. However, in order for these curable resins to exhibit sufficient shear adhesive strength, peel strength, or mechanical strength on average, heat treatment is necessary, and heat treatment is not preferable because the application target is likely to be adversely affected by heat. This is inconvenient when installing large areas, long items, or outdoors. As a solution to these drawbacks, room temperature curable epoxy resins, epoxy (meth)acrylates made by reacting epoxy resins with (meth)acrylic acid, and urethane (meth)acrylates have been reported. In reality, these adhesives either do not have sufficient shear adhesive strength or peel strength, or require heating in order to obtain the desired adhesive strength.

By curing the curable composition of the present invention at room temperature, a cured product having high shear adhesive strength and peel strength can be obtained while retaining the flexibility of the resin or without significantly impairing it. In particular, shear adhesive strength and shear adhesive strength usually have contradictory tendencies, and conventionally it has been difficult to satisfy both.However, according to the composition of the present invention, a cured product that satisfies both of them can be obtained. It will be done. As described above, the composition of the present invention can be used in paints, adhesives, sealants, anti-corrosion materials, human resources, wire insulation materials, molding materials, etc., since a cured product with high strength can be obtained while maintaining elongation. is expected to have a wide range of applications,
Furthermore, since this property can be exhibited by curing at room temperature, it is suitable for objects that cannot be heated due to their material nature, large-area objects, long objects, outdoor structures, etc., and is used, for example, as a steel plate paving material.
