  • Publication number: 20150099818
    Abstract: A two part composition comprising a Part A and a Part B, wherein Part A comprises an oligomer having both isocyanate and acrylate moieties, and an organic peroxide capable of generating free radicals upon decomposition; and Part B comprises a polyol, and a catalyst that can decompose the organic peroxide. In one form, the two part composition of a Part A and a Part B are in admixture. By combining Part A and Part B the isocyanate moieties react with the polyol to produce a combination of a urethane acrylate oligomer, organic peroxide and the catalyst. Then in either order, the combination is exposed to sufficient actinic radiation to polymerize at least a portion of the urethane acrylate oligomer; and the catalyst decomposes the organic peroxide thus generating free radicals, which free radicals polymerize at least a portion of the urethane acrylate oligomer.

  • Patent number: 8134132
    Abstract: A device and method for exposing light sensitive substrates to a concentrated light source. The device is suitable for curing substances such as photosensitive sensitive inks, adhesives, and photographic elements. Ultraviolet or visible light is emitted from an array of LED's, and then directed by an array of light guides to a light concentrator having a light input region along its length. The light is then concentrated and emitted from a light output region along the length of the light concentrator to a photosensitive target to be exposed.

  • Patent number: 8052829
    Abstract: The invention relates to photopolymerizable compositions containing an oxonol dye, which compositions cure by exposure to ultraviolet and/or visible radiation and whose visible color is substantially reduced during exposure. More particularly, the invention pertains to photopolymerizable compositions comprising a pyridin-2,6-dione oxonol dye in an admixture of a polymerizable component and a photopolymerization initiator. Such compositions find use as adhesives, coatings, and the like. The disappearance of the visible color of the oxonol dye acts as an indicator of full cure of a photopolymerizable composition.

  • Patent number: 7802910
    Abstract: The invention provides a light guide exposure device comprising light emitting diodes arranged in a single array defining an array width and a flexible light guide having a proximal end and a distal end; the proximal end defining a proximal end diameter. The array is positioned in substantial alignment with the light guide proximal end to direct substantially all of the light from the array to the proximal end. There is no optical element between the light emitting diodes and the proximal end which optical element would decrease the intensity of light directed from the light emitting diodes to the proximal end. The array width is substantially equal to the proximal end diameter.
