Abstract
A composition suitable for forming a paint marking on a roadway comprises a polyfunctional acrylate having at least four acrylate groups, an epoxy component and a polyfunctional amine. The polyfunctional 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 high crosslinked material having a no track time of less than about five minutes.

A polymeric composition exhibiting a fast cure rate, said composition consisting essentially of:
- a polyfunctional acrylate component;
- wherein the polyfunctional acrylate is a condensation reaction product of two hydroxyl functional (multi) acrylates;
- wherein the hydroxy functional (multi) acrylates is selected from the group consisting of dipentaerythritol pentacrylate, ethoxylated dipentaerythritol pentacrylate, propoxylated dipentaerythritol pentacrylate, and mixtures thereof;
- an epoxy resin component;
- and from about 20 to about 35 percent by weight of a polyfunctional amine component;
- wherein the polyfunctional amine component comprises at least one primary amine group;
- wherein said polyfunctional acrylate component and said polyfunctional amine component have sufficient functionalities such that said polyfunctional acrylate component reacts with said polyfunctional amine component to form a secondary amine component, and wherein said secondary amine reacts with said epoxy resin component such that a chemically high crosslinked polymeric material is formed, and wherein said polymeric composition has a no track time of less than about 5 minutes.
A polymeric composition exhibiting a fast cure rate, said composition consisting essentially of a decfunctional acrylate component formed from the condensation reaction product of two dipentaerythritolpentacrylate(s);
- an epoxy resin component;
- and from about 20 to about 35 percent by weight of a polyfunctional amine component;
- wherein the polyfunctional amine component comprises at least one primary amine group;
- wherein said decfunctional acrylate component and said polyfunctional amine component have sufficient functionalities such that said decfunctional acrylate component reacts with said polyfunctional amine component to form a secondary amine component, and wherein said secondary amine reacts with said epoxy resin component such that a chemically high crosslinked polymeric material is formed, and wherein said polymeric composition has a no track time of less than about 5 minutes.
