  • Patent number: 5019426
    Abstract: A method of sealing the surfaces of porous carbon and graphite articles by impregnation at ambient pressure using a treating solution comprising a high temperature polymerizable liquid resin. The liquid treating solution, when upon the surface of the article, is of sufficiently low viscosity to allow infiltration of the treating solution into the pores of the surface of the article. The treated article then undergoes a controlled heating cycle, which cures the infiltrated resin in situ. Subsequent treatments and surface conditioning techniques are utilized to produce a thin, level, liquid and gas impervious coating on the surfaces of the article.
