The present invention relates to a novel epoxy resin curing system comprising a cationic latent catalytic curing agent containing a hexafluoroantimonate, characterized by exhibiting no shrinkage of volume or inducing an expansion of volume during the curing reaction of the epoxy resin.
By the use of the epoxy resin curing system comprising a cationic latent catalytic curing agent containing a hexafluoroantimonate, it is possible to inhibit the shrinkage of volume or to induce the expansion of volume during the curing reaction of the epoxy resin. The development of such curing systems made it possible to improve the dimensional stability and to remove the residual stress, which has caused problems for decades in the production of various molded articles. Furthermore, the curing systems according to the present invention have excellent adhesive properties, thereby making it possible to develop adhesives for accurate spatial infiltration.
