Abstract
A highway marking paint is provided formed from a waterborne latex paint and porous silica. The silica enables the paint to achieve sufficient viscosity to permit the application of a highway marking of at least 40 mil and preferably at least 120 mil. The highway marking paint can also include retroreflective glass beads. Optionally, the highway marking paint further includes an acrylic polymer emulsion.
