  • Patent number: 10723921
    Abstract: Coumarin modification of epoxies provide for epoxy adhesives that fluoresce under short wave ultraviolet irradiation while remaining invisible under normal light. Furthermore, these modified epoxy adhesives can have increased adhesive bond strengths. In addition, photochemical curing of an epoxy modified coumarin and a hardening agent with UV irradiation at certain wavelengths affords an epoxy adhesive composition. Further UV irradiation of the composition at certain wavelengths causes photoscission, which breaks the crosslinks that make the cured epoxy adhesive insoluble and intractable.
    Type: Grant
