  • Patent number: 7252786
    Abstract: Thermoformable, Long Lasting Phosphorescent Acrylic Resin for Castings, Adhesives, Moldings, Coatings and Liquid Inlays are manufactured from thermosetting acrylic syrup, promoters, additives, fillers and phosphorescent pigments and are used to manufacture thermoformed, cast, coated, inlayed, molded articles and reinforced composites. These phosphorescent resins glow-in-the-dark, and exhibit a long lasting, bright glow after exposure to light (photoluminescence). The use of suspending agents keeps the heavy phosphorescent pigments in suspension and results in a phosphorescent resin that has a long shelf life. The Phosphorescent Acrylic Resin compositions disclosed herein may be used in thermoform and thermoset applications to produce solid-surface acrylic resin products with a robust glow-in-the-dark property.

  • Publication number: 20060038161

These phosphorescent resins glow-in-the-dark, and exhibit a long lasting, bright glow after exposure to light (photoluminescence). Products made from this Thermoformable, Long Lasting Phosphorescent Thermosetting Acrylic Resin overcome deficiencies in prior art, because they are thermoformable to a tighter radius, more ductile, tougher and more flexible, extremely weather resistant and have a longer afterglow. Furthermore, products made from this phosphorescent acrylic thermosetting resin have the novel ability to be joined using a phosphorescent thermoset acrylic adhesive that results in a chemical bond without the need of surface preparation.
