PURPOSE: A tile joint repairing composition is provided to have excellent mechanical and chemical properties without discoloration, to have excellent transparency, and to have excellent initial moisture resistance. CONSTITUTION: A tile joint repairing composition comprises 100.0 parts by weight of a base material and 30-60 parts by weight of a hardener part. The base material comprises an epoxy modified resin which has an epoxy functional group and an isocyanate functional group obtained by a reaction of a hydrogenated epoxy resin and alicyclic isophorone diisocyanate; an epoxy functional group-containing reactive diluent; a pigment; and additives. The hardener comprises alicyclic-modified amine which is obtained by an addition reaction of 1,3 bis(aminomethly)cyclohexane to an epoxy resin, a catalyst, and an additive. |
