20080242757 | UV CURABLE COATING COMPOSITION - The present invention is directed to a composition curable by radiation having a wavelength of 300 nm or more, a method of producing a coated substrate using such composition and the coated product so-produced. More particularly, the composition of the present invention comprises A) from about 1 to about 99% by weight of a specific aqueous polyurethane dispersion having a solids content of from about 20 to about 50% by weight, B) from about 1 to about 99% by weight of an aqueous polyester acrylate/urethane dispersion having a solids content of from about 20 to about 60% by weight, C) one or more photoinitiators, and D) water or a mixture of water and solvent | 10-02-2008 |
20100260941 | REINFORCED UV-A CURABLE COMPOSITE COMPOSITIONS AND METHODS - 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. | 10-14-2010 |
20110059262 | AQUEOUS FLOOR COATINGS BASED ON UV-CURABLE POLYURETHANE DISPERSONS - The present invention is directed to a process for coating a wood substrate, the coating composition curable by radiation having a wavelength of 320 nm to 450 nm and the coated product so-produced. | 03-10-2011 |
20120160437 | PROCESS FOR THE PRODUCTION OF SIZED AND/OR WET-STRENGTH PAPERS, PAPERBOARDS AND CARDBOARDS - 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. | 06-28-2012 |
20130202808 | LOW GLOSS RADIATION-CURABLE COMPOSITIONS - A process of producing a low gloss coating curing the coating using UV-A radiation. | 08-08-2013 |
20130302530 | DIRECT-TO-METAL RADIATION CURABLE COMPOSITIONS - A process of directly coating a metal substrate and curing the coating using radiation sources such as UV radiation having a wavelength of 200 nm and above. Furthermore, compositions of the invention can be used as a tie-coat for coatings that do not bond well directly to various metal substrates. | 11-14-2013 |
