    Abstract: The invention is directed to the use of medium to high power (greater than or equal to 1 kW) and medium to high energy (greater than or equal to 1 MeV) electron beam or X-ray to cure coatings in thick complex three dimensional automotive bodies. The medium to high power, medium to high energy has sufficient throughput and penetration to permit curing through multiple layers of steel and, therefore, is able to penetrate shadows caused by the bends, folds and curves in automotive bodies. In addition, the medium to high power, medium to high energy beam has sufficient throughput and penetration to cure the thicker coatings that accumulate in surface cracks and crevices. The invention permits the use of electron beam curable coatings and, thereby, reduces the fire hazard, hazardous air pollutant, and volatile organic problems associated with the non-reactive solvents used in the solvent based paints conventionally employed in the automotive industry.

Thereafter, etching treatment and so on are performed, and a series of these treatment and processing steps are performed a predetermined number of times. The coating film has been formed on the rear surface of the substrate at the time for the etching treatment, so that even if the coating film gets minute scratches, the rear surface of the substrate itself is protected by the coating film and thus never scratched. Further, since the coating film on the rear surface of the substrate is removed immediately before the exposure processing, the rear surface of the substrate can be flat for the exposure processing.

  • Patent number: 7043297
    Abstract: A reservoir electrode assembly of the present invention for an iontophoretic drug delivery device includes an electrode and a hydrophilic reservoir situated in electrically conductive relation to the electrode. The hydrophilic reservoir is formed from a bibulous hydrophilic cross-linked polymeric material having a first surface and a second surface that is adhesively adherent to the electrode. The first surface of the polymeric material is releasably adhesively adherent when applied to an area of a patient's skin. The polymeric material has a cohesive strength forms an adhesive bond with a bond strength between the second surface of the polymeric material to the electrode that is greater than the cohesive strength of the polymeric material.

  • Patent number: 7031796
    Abstract: A method for limiting exposure of a substrate to potentially damaging radiation from a radiating apparatus. A database of information associated with the substrate is compiled, and the substrate is identified prior to processing the substrate on the radiating apparatus. The database of information associated with the substrate is accessed, including its past irradiation history of dosage and type of irradiation, based on the substrate identification, and the operation of the radiating apparatus is selectively modified based at least in part on the information associated with the substrate.

  • Patent number: 7011913
    Abstract: A method of making a reflective film includes the steps of: (a) preparing a cholesteric mixture that includes a cholesteric liquid crystal material and at least one type of polymerizable compound; (b) forming a cholesteric mixture layer in which the cholesteric liquid crystal material forms a helical structure, having continuously changing helical pitches, approximately along a normal to the layer; and (c) exposing the cholesteric mixture layer to an actinic ray at a temperature, at which the cholesteric mixture exhibits a cholesteric phase, thereby polymerizing the at least one type of polymerizable compound. In this method, a Tni point of the cholesteric mixture increases by performing the step (c).

  • Patent number: 6900252
    Abstract: There is provided a radiation-curable coating or packaging composition containing vinyl acrylate and one or more additional components, wherein the composition does not contain a photoinitiator, and the composition polymerizes upon irradiation. The irradiation forms a polymer that demonstrates thermal stability and abrasion resistance, and functions as a moisture barrier. The resulting polymer does not contain any photoinitiator and is therefore useful as a coating or packaging material for foods, or as a coating or packaging material for any application where the exclusion of photoinitiator, and especially residual photoinitiator, is preferred, such as an outdoor weatherable application. A feature of the invention is that the polymerization through exposure to radiation of a composition containing vinyl acrylate may also initiate the polymerization of one or more of the additional components within the composition that would not ordinarily polymerize in the absence of a photoinitiator.

  • Patent number: 6893686
    Abstract: A non-fluorocarbon oil and grease barrier packaging for storing materials, particularly products that need oil and grease resistant characteristics. The barrier packaging does not contain fluorocarbons, which improves the environmental rating of the oil and grease barrier packaging. The packaging is made by applying an acrylate based overprint varnish to a substrate and then curing the overprint varnish with a curable energy source, which regulates a cross-link density of the overprint varnish. Application can be flexography, rotogravure, or either rod or blade coated. The overprint varnish possesses oil and grease resistant characteristics, which allows packaging producers to forego use of oil and grease resistant coated substrates in their packaging manufacturing processes.
