Hydroxyl end-capping agent A is employed into the polymerization of aqueous hydroxyl-end polyurethane dispersion, which is applied in two-component aqueous polyurethane vanish. This article studies the effects on the performance of this dispersion by reaction temperature,polyester polyol, chain-extender, end-capping agent. Two-component aqueous polyurethane vanish formulated by this dispersion gives good workability.Hardness and adhesion are also determined.
