    摘要: The present invention relates to a process for the production of sized and/or wet- strength papers, paperboards or cardboards, wherein an aqueous radiation-curable dispersion containing water and at least one polymer, characterized in that the polymer contains cationic groups, is mixed with suspended wood pulp and/or chemical pulp and this mixture is sieved, pressed, thermally dried and then radiation-cured, characterized in that the dispersion is employed in amounts, based on its non-aqueous content in relation to the solid content of the wood pulp and/or chemical pulp, of from 0.001 to 10 wt.%, the papers, paperboards and cardboards produced by this process, and compositions comprising suspended wood pulp and/or chemical pulp and an aqueous radiation-curable dispersion containing at least one polymer, characterized in that the polymer contains cationic groups.

    摘要: The present disclosure is directed to a process for forming a reinforced ultraviolet (UV) radiation-curable composite. The composite may be formed by applying reinforcing layers and resin layers to a substrate. The resin composition may include an aliphatic urethane acrylate oligomer, a polyfunctional acrylate monomer, and a photoinitiator. The composite formed on the substrate may be exposed to UV radiation to cure the composite on the substrate. The composite may be characterized in that it is cured within 10 minutes of exposure to UV radiation and does not exhibit oxygen inhibition effects, such as, for example, surface tack. The reinforced UV-curable composite may find utility, for example, as a rapid field repair patch in aerospace applications, among others.
