  • Excimer fluorescence method for determining cure of coatings
    Patent number: 5556663
    Abstract: A fluorophore is added to or chemically attached to a curable release coating and the release coating is applied to a substrate. By exposing the release coating to an ultraviolet light source and measuring the intensity ratio of the dimer to monomer fluorescence, the cure of the release coating can be monitored. This method can be used as an on-line cure monitor in order to determine and control the extent of cure of coated substrates particularly silicone release liners.
