  • Patent number: 6797102
    Abstract: A co-mingled polyurethane-polyvinyl ester composition can be used as a coating, which has good scratch, mar and solvent resistance. The coating is derived from a waterborne polyurethane solution containing free radically polymerizable monomers such as acrylate, ultraviolet light initiators, and optionally urethane crosslinking agents. A process for forming the co-mingled polyurethane-polyvinyl ester composition comprises drying the waterborne polyurethane containing the polymerizable monomers therein and radiation polymerizing, as by ultraviolet light, the free radically polymerizable monomers on a substrate such as a plastic sheet to form a laminate. Subsequently, the laminate can be utilized to form a coating on a product as by thermoforming, where if urethane crosslinking agents are utilized, the polyurethane will be crosslinked.

  • Patent number: 6793861
    Abstract: The present invention is a process for producing an injection-molded thermoplastic workpiece having a thermoset coating bonded thereto, comprising the steps of introducing in three stages into a closed mold a thermoplastic material, such as a polyolefin, heated to a temperature above its melting point and molding said material to form a workpiece; cooling the workpiece to a temperature less than its melt temperature introducing a thermoset coating composition into the closed mold to cover at least a portion of a surface of the workpiece. The mold is then opened and the workpiece is removed after the coating composition has at least partially cured. The invention is also directed to a molded article made by the described process.

  • Patent number: 6727344
    Abstract: Monofunctional polyfluorooxetane oligomers and polymers are prepared by the cationic polymerization of fluorooxetane monomers with a monoalcohol. The fluorooxetane oligomers or polymers can be copolymerized with generally cyclic ethers. Alternatively, the polyfluorooxetane oligomer or polymer having a single hydroxyl end group can be functionalized with a variety of compounds so as to yield a functional end group such as an acrylate, a methacrylate, an allylic, an amine, etc., with the functionalized oligomer or polymer being suitable for use in radiation curable or thermal curable coating compositions. These functionalized polymers can be copolymerized and cured to provide improvements in wetting and surface properties that have previously been provided by migratory chemicals such as waxes and oils.

  • Patent number: 6686051
    Abstract: A polyester polymer includes at least one hydroxyl terminated polyoxetane block containing repeat units derived from polymerizing at least one oxetane monomer having a pendant —CH2—O—(CH2)n—Rf group wherein said Rf group is partially or fully fluorinated. A preferred process for forming said polymer is by reacting a hydroxyl terminated polyoxetane with a polycarboxylic acid under appropriate conditions to form an ester linkage and then adding and reacting that product with polyester forming reactants. The polyester polymer containing at least one polyoxetane block therein when reacted with an amino resin curative can be used as a coating on a substrate wherein the coating has dry erase properties. The coated substrate can be used as prepared or applied to yet other substrates.

  • Patent number: 6676877
    Abstract: A mold runner for a runner or sprue type injection molding apparatus. The mold runner allows the passage of a substrate material from an injection source into a mold cavity and contains a containment shroud which utilizes the relative incompressibility of the substrate material in the containment shroud which prevents an in-mold coating, which is injected into the mold cavity in a subsequent step, from flowing into the injection substrate source thereby contaminating the same.

  • Patent number: 6673889
    Abstract: Acrylate, or methacrylate, or allylic, functionalized polyfluorooxetanes are disclosed for use in radiation curable coating compositions. These acrylate, or methacrylate, or allylic, functionalized polymers provide improvements in wetting and surface properties that have previously been provided by migratory chemicals such as waxes and oils. The partially or fully fluorinated side groups of the fluorooxetanes are believed to be disproportionately present at the interfaces between the coating and the substrate and between the coating and the atmosphere.

  • Patent number: 6589628
    Abstract: A method and system for forming an article having an optical effect is provided. An original texture is obtained which is digitized using a scanner. The scanner causes a shadow effect on the texture based on the scanning direction. The digitized texture is then edited to define a selected shape. The texture within the selected shape is offset such that its direction is changed. The digitized texture is then engraved by a laser onto the surface of an article. The selected shape is then visually distinct from the other areas of the texture at certain viewing angles caused by the difference in their texture direction. With the present invention, lines or seams between areas of the texture are eliminated.

  • Patent number: 6426129
    Abstract: An adhesive rubber article of the type having a release liner covering its tacky, adhesive surface to prevent the adhesive rubber article from adhering to various substrates or to itself prior to its intended use includes an impression or mark presented on one or more surfaces for facilitating the alignment and application of the adhesive rubber article on one or more substrates. The release liner has been scored, perforated or otherwise cut in a longitudinal direction of the article such that the scoring of the release liner further produces a visual guide on the adhesive rubber article. Thus, upon removal of the release paper, the guide may be used to align and apply the adhesive rubber article to the various substrates. These adhesive rubber articles are particularly useful within the roofing industry for bonding panels of rubber membranes together or for use as flashing.

  • Patent number: 6417270
    Abstract: A process of preparing a diblock/triblock composition in a single reaction vessel includes reacting a first monomer, such as styrene, with a first portion of an anionic catalyst in a suitable solvent to form a first polymer block of the triblock. A second step includes adding a second monomer, such as butadiene (when the first monomer is styrene). This forms a second block of the triblock and a first block of the diblock. A further addition of the first monomer completes the diblock and triblock interpolymers. At least a portion of the diblock and/or triblock interpolymers are functionally terminated with a functional terminating agent, such as cyclohexene oxide or isopropanol, to provide the blocks with a functional group. The functional group and the proportion of the interpolymers functionally terminated are selected to provide desired adhesive properties for a particular application.
