COATED GRANULAR CURING AGENT FOR A RADICALLY CURABLE COMPOUND AND ANCHOR BOLT-FIXING COMPOSITION COMPRISING THE SAME

摘要

Disclosed is a coated granular curing agent, which is for use in curing at least one first radically curable compound selected from the group consisting of a radically curable resin and a radically polymerizable monomer and which comprises an organic peroxide granule, wherein the organic peroxide granule has an entire surface thereof coated with a layer of a cured resin derived from at least one second radically curable compound selected from the group consisting of a radically curable resin and a radically polymerizable monomer, and wherein the first and second radically curable compounds are the same or different. The coated granular curing agent of the present invention is advantageous not only in that the curing agent can be handled with ease, but also in that the curing agent can be uniformly dispersed in a radically curable compound, so that it exhibits excellent curing performance. Therefore, the coated granular curing agent of the present invention can be advantageously used to provide a one-pack type anchor bolt-fixing composition which is not only capable of stably fixing an anchor bolt to a base while enjoying high fixation strength, but also can be stored at room temperature for a period of time as long as 1 month or longer without suffering any degradation. <IMAGE>
