TWO-COMPONENT CURABLE AQUEOUS URETHANE-ALKYD RESIN COMPOSITION AND USE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a two-component curable aqueous resin composition capable of effectively expressing characteristics of both polyurethane resins and alkyd resins in a short time.

SOLUTION: The two-component curable aqueous resin composition contains a polyurethane-alkyd resin emulsion (A) having an active hydrogen atom in the molecule, and a curing agent (B) composed of a polyisocyanate which is dispersible in the emulsion (A). The composition further contains a metal drier (C), and the alkyd resin component of the polyurethane-alkyd resin emulsion (A) may contain an unsaturated fatty acid as a constitutional unit. The curing agent (B) may be composed of a dispersible polyisocyanate which is obtained through a reaction between a polyisocyanate and a surface-active or dispersible component having an active hydrogen atom which is reactive with an isocyanate group.
