Abstract
A flowable luminescent coating composition includes a curable thermoset resin, a filler material, two or more solvents, a plasticizer, a stabilizer, phosphorescent aluminate particles. The phosphorescent aluminate particles are present in the flowable luminescent coating composition at a concentration of 30 to 70 % by weight of the composition. The composition in a cured form has an intensity of glow of 1-50 candelas per square meter for a period of 0.1 to 2 hours upon excitation with ultraviolet light for 5 to 120 seconds. A glow-in-the-dark (GiD) film, a GiD traffic sign, and a GiD system.

A curable and flowable luminescent epoxy coating composition, comprising:
- a liquid mixture comprising:
- a curable epoxy resin,
- two or more solvents,
- a plasticizer, and
- a stabilizer;
- a filler material;
- and
- phosphorescent aluminate particles;
- wherein the phosphorescent aluminate particles are present in the curable and flowable luminescent epoxy coating composition at a concentration of 30 to 70 wt. % based on a total weight of the flowable luminescent coating composition;
- wherein the phosphorescent aluminate particles and the filler material are suspended in the liquid mixture;
- and
- wherein the curable and flowable luminescent epoxy coating composition in a cured form has an intensity of glow of 1-50 candelas per square meter for a period of 0.1 to 2 hours upon excitation with ultraviolet (UV) light for 5 to 120 seconds.
