Abstract
A composition suitable for forming a paint marking on a roadway comprises a polyfunctional urethane acrylate having at least two acrylate groups, an epoxy component and a polyfunctional amine. The polyfunctional urethane acrylate reacts with the polyfunctional amine to form an adduct with secondary amine groups. The secondary amine reacts with the epoxy component to yield a chemically crosslinked material having a no track time of less than about ten minutes.
