AQUEOUS PIGMENTED COATING COMPOSITION WITH IMPROVED OPEN TIME COMPRISING CROSSLINKABLE OLIGOMER(S) AND DISPERSED POLYMER(S)

摘要

An aqueous coating composition with an improved open time comprising (a) a crosslinkable water-dispersible oligomer(s); (b) a dispersed polymer(s), (c) a pigment(s) with an oil absorption number <=25g oil / 100g pigment and optionally (d) a Newtonian-like thickener(s) and (e) a thixotropic thickener(s) wherein the weight ratio of (a) : (b) is in the range of from 10:90 to 60:40; wherein (d) + (e) = 0.1 to 10 wt % and wherein said composition when drying to form a coating has a tack-free time of <= 24 hours.
