Abstract
A polymeric composition exhibiting a fast cure rate composition comprises a polyfunctional urethane acrylate component; an epoxy component; and a polyfunctional amine component. The polyfunctional acrylate component and the polyfunctional amine component have sufficient functionalities such that the polyfunctional urethane acrylate component reacts with the polyfunctional component to form a secondary amine component. The secondary amine then reacts with the epoxy component such that a crosslinked polymeric material is formed.
Claims10
A method for forming a paint marking on a roadway, said method comprising:
- applying a traffic paint composition to a surface of the roadway, the traffic paint composition comprising a polymeric composition and a pigment, wherein the polymeric composition comprises a polyfunctional urethane acrylate component having more than four acrylate functionalities;
- an epoxy component;
- and a polyfunctional amine component;
- wherein said polyfunctional acrylate component and said polyfunctional amine component have sufficient functionalities such that said polyfunctional urethane acrylate component reacts with said polyfunctional amine component to form a secondary amine component, and wherein said secondary amine reacts with said epoxy component such that a chemically crosslinked material is formed, said traffic paint composition having a no track time of less than about 10 minutes.
