Aqueous vinyl polymer coating compositions

摘要

An aqueous coating composition comprising a crosslinkable water-dispersible vinyl oligomer(s) wherein said composition when drying to form a coating has an open time of at least 20 minutes, a wet edge time of at least 10 minutes, a tack free time of <=20 hours and an equilibrium viscosity of <=5,000 Pa.s at any solids content when drying in the range of from 20 to 55 wt % using any shear rate in the range of from 9±0.5 to 90±5 s<-1 >and at 23±2° C.
