ABSTRACT:
This invention relates to ambient-curing water-based binder, coating and adhesive compositions. These compositions are prepared by mixing (1) an acidic first component containing an aqueous dispersion of polymer latex, said polymer being alkali-curable and polymerized from a monomer mixture containing quaternary ammonium monomer, and an epoxy resin, together with (2) an alkaline second component containing an amine curing reagent. The resulting mixture of the first and second components is alkaline, cures quickly at room temperature, and yields films with high film strength, durability, and excellent heat and water resistance.
