Abstract:
1. A pore-sealing agent for a spray deposit, which is free from a polymerizable vinyl group-containing solvent, consisting of an epoxy group-containing component, a hardener and a hardening accelerator, wherein said epoxy group-containing component is a mixture which consists of triglycidyl ether compound having three epoxy groups in one molecule having a viscosity and at least one compound selected from among an alkylenediglycidyl ether compound and a cyclic aliphatic diepoxy compound, each of which contain two epoxy groups in one molecule thereof and each of which having a viscosity; and excluding said hardener and said hardening accelerator, more than 50 wt % and not more than 80 wt % of said triglycidyl ether compound is mixed with an entirety of said epoxy group-containing component, wherein the viscosity of said triglycidyl ether compound at 25° C. is not more than 500 mPa·s, the viscosity of said alkylenediglycidyl ether compound at 25° C. is not more than 30 mPa·s, and the viscosity of said cyclic aliphatic diepoxy compound at 25° C. is 10 mPa·s, with the proviso that the viscosity of said triglycidyl ether compound is higher than the viscosity of said at least one compound selected from among said alkylenediglycidyl ether compound and a cyclic aliphatic diepoxy compound, each of which contain two epoxy groups in one molecule thereof, and wherein said hardener contains an acid anhydride.
