Abstract
A low viscosity, fast-curing binder for textile substrates is produced by admixing an aqueous emulsion copolymer latex with an aqueous solution copolymer formed by the copolymerization of an olefinically unsaturated polycarboxylic acid and an olefinically unsaturated monocarboxylic acid. Viscosities in the range of about 2 cps at 25% total solids to about 1000 cps at 35% total solids are realized by using solution copolymers containing about 40%-75% by weight of polycarboxylic acid.
