Abstract:
A fast hardening aqueous migration-resistant binder composition comprising:(1) a fast hardening aqueous coating composition comprising: (a) from about 95 to about 99 weight percent, based on the weight of dry materials in the composition, of an anionically stabilized aqueous emulsion of a copolymer having a Tg of from about 10Â° C. to about 50Â° C. the copolymer comprising in polymerized form a polymerization mixture containing two or more ethylenically unsaturated monomers, wherein, based on the total weight of all ethylenically unsaturated monomers in the polymerization mixture, from 0.2 to about 4 weight percent of the monomers are &agr;,&bgr;-ethylenically unsaturated aliphatic carboxylic acid monomers; (b) from about 0.2 to about 5 weight percent of a polyethyleneimine having a number average molecular weight of from about 250 to about 2,000; and (c) from about 0.2 to about 5 weight percent of a volatile base; and (2) an organic filler, an inorganic filler, an organic fiber, an inorganic fiber, or a mixture thereof.
