Abstract
A one-pack type liquid epoxy resin composition for balancing rotators comprises an epoxy resin, a curing agent, a curing accelerator, an inorganic filler, and a thixotropic agent as main components, wherein said curing agent is dicyandiamide or a dibasic acid dihydrazide and said curing accelerator is a tertiary amino group-containing compound obtained by reacting a polyfunctional epoxy compound, a compound having a tertiary amino group and at least one active hydrogen in the molecule, and a carboxylic acid anhydride. Further, a method for balancing a rotator comprises correcting unbalance of the rotator caused at rotation by applying a balancing material consisting of the above epoxy resin composition to the rotator by an automatic unbalance-correcting apparatus.
