摘要

Methods of applying stable synthetic resin compositions to porous material the synthetic resin compositions comprising: (1) a synthetic resin; (2) a polyvalent metal complex coordination compound; and (3) a water-soluble, ionically active ammonium or alkali metal salt of an acid capable of being chemically converted into an ionically inactive polyvalent metal salt of said acid by chemical reaction and precipitation or sequestration of said polyvalent metal salt, and substantially immediately destroying the stability of the synthetic resin compositions to precipitate the resin on the porous materials under controlled migration conditions.
