PURPOSE: A resin impregnator is provided to ensure high permeation efficiency of an impregnation composition due to low viscosity, to prevent deformation or discoloration at a high temperature, and to avoid corrosion or oxidation in washing. CONSTITUTION: A resin impregnator comprises: an acrylic monomer including a first acrylic monomer for imparting soft property of a hardened material, a second monomer for imparting hardening property, and a third acrylic monomer for bonding ability between monomers; an antioxidant; a photostabilizer; and a surfactant consisting of a first surfactant based on a non-ion higher alcohol and a second surfactant based on non-ionic fatty acid ester.
