ABSTRACT:
The present invention provides fast drying aqueous compositions, suitable for use in making roadway markings, as well as the road markings made therefrom, the compositions comprising one or more anionically stabilized binder having a phosphorus acid functional polymer component having a glass transition temperature (Tg) range of from −30° C. to 60° C. and a polyfunctional amine component in combination with one or more volatile base in an amount sufficient to stabilize the composition by at least partially deprotonating the polyfunctional amine, and one or more phosphorus acid surfactant, such as an alkyl ethoxylated phosphate. Further, the present invention provides two component compositions comprising the above composition as one component and a second component comprising an absorber and/or the polyfunctional amine component. The fast-drying compositions are viscosity stable and provide wear resistant fast dry coatings even in humid application conditions.
