Abstract
Abstract A rapid hardening, solvent-free water-based adhesive composition includes an amount of an aqueous latex dispersion of polyester-polyurethane synthetic resin, an amount of rosin acid ester hardener, an amount of a thickener together with an amount of inert filler and an amount of a plasticizer/extender in sufficient water to adjust the percent solids to the desired amount. Optionally, the adhesive composition also includes an amount of polyisocyanate cross-linker to provide additional environmental stability.
