Reactive, Fluorescent Epoxy Monomers for Making Epoxy Thermosets Visible Under Ultraviolet Light
This technology allows for the easy identification of epoxy repairs using ultraviolet (UV) light. A fluorescent dye is covalently bonded to the epoxy group molecule, preventing it from leaching out of the cured adhesive. This dye, which emits a bright fluorescence under UV light, does not reduce the adhesive strength of the epoxy and will not lose its...

Color-Free, Thermally Reworkable Diels-Alder Epoxies with Liquid Precursors
Researchers at the University of Arizona have developed an epoxy which reverts to a liquid upon application of heat. This epoxy is colorless and contains liquid precursors, which can be mixed at room temperature, making it an ideal adhesive for art conservation. This invention solves the issue of irreversibility in epoxy adhesives. Background: Epoxies...
