Abstract
PURPOSE: To prevent reemulsification of an aqueous resin emulsion without lowering adhesion to adherend and the flexibility of paint film, by mixing a specified masked isocyanate curable with water at ordinary temperature in a aqueous resin emulsion which is useful as a coating agent, etc.
CONSTITUTION: A urethane prepolymer with 2 or more free NCO groups is obtained by the reaction of a polyisocyanate (i) and a hydrophilic polyol prepolymer (ii) (e.g., ethylene oxide addition polymers of a molecular weight of 1,000W 20,000). And, 2.0W10pts.wt. masked isocyanate, obtained by the reaction of the said urethane prepolymer (A) and a masking agent (B) selected from a heterocyclic compound having a skeleton of the formula in its molecule, hydroxypyridine, hydroxyquinoline, and a phenol of 5W9.5pka in a proportion of OH/NCO or NH/NCO equivalent ratio of 0.05W2, is mixed with 100pts.wt. (solid content) emulsion to obtain a modified emulsion.
EFFECT: The application time (pot life) of the emulsion can be elongated.
