摘要： A method for isolating plastic products produced by polymerization of resin with proton beams is disclosed. The method comprises a liquid resin added with a reactive dye that changes from transparent or colorless to color when activated by the proton beam or the chemical polymerization process to reveal polymerization within a polymerizable resin. The change in color is correlated to the energy delivered to the resin by a proton beam, electromagnetic radiation, or heat. The reactive dye is placed into a plastic container. The proton beam is directed into the container to polymerize the resin. When irradiation is complete, the container of frozen resin is opened at the top and bottom and placed on top of the column of water containing a density gradient provided by dissolved salt. The partially cured product is fully cured while suspended in the density gradient by application of heat or ultraviolet radiation.

摘要： Adhesive compositions disclosed herein can be applied to substrates using flexo-printing (via, e.g., photopolymer plate); cured to a hardened, tack-free state; and readily be rendered tacky on application of heat and pressure to accurately transfer foil to the substrates. An example adhesive composition includes a monomer component, an oligomer/resin component including one or more oligomers and one or more inert thermoplastic resins that are soluble in the monomers, and, where required, one or more free radical polymerization initiators.

摘要： A composition that can be activated by irradiation and cured by moisture comprises (A) one or more moisture-curable compounds from the group of alkoxy silanes, (B) at least one acid generator releasing an acid when exposed to actinic radiation, and (C) at least one carbonyl compound and/or carbonyl derivative selected from the group of aldehydes, ketones, hemiacetals and hemiketals. Moreover, the compositions according to the present invention can additionally contain an alcohol and/or thiol (D), a catalyst for moisture-curing (E), a radiation-curable compound (F), a photoinitiator for radical polymerization (G), and further additives (H). After activation of the acid generator the composition cures even in high layer thicknesses independently of the ingress of external moisture.
Furthermore, a method for the bonding, molding, sealing and coating of substrates using the composition is described.
