  • Patent number: 9920526
    Abstract: Structural systems having coated structural members with enhanced durability are provided, along with methods of making and using the same. Structural members including at least one coating material applied to a substrate that comprises at least one protrusion may exhibit increased strength and/or durability and may be less likely fail during use. For example, structural members as described herein exhibit an improved resistance to cracking when a force is applied to the protrusion. Structural systems according to embodiments of the present invention can be suitable for use in a variety of applications, including in ready-to-assemble furniture or cabinetry applications or as building and construction materials such as wall board, flooring, trim, and the like.

  • Patent number: 9616457
    Abstract: Exemplary pressurization and coating systems, methods, and apparatuses are described herein. In certain embodiments, pressurization systems, methods, and apparatuses are used in conjunction with coating systems, methods, and apparatuses to control pressure about a substrate after a coating material is applied to a surface of the substrate. An exemplary system includes a die tool configured to apply a coating material to a substrate passing through the die tool and a pressurization apparatus attached to the die tool and forming a pressurization chamber. The pressurization apparatus is configured to receive the substrate from the die tool and control pressure about the substrate in the pressurization chamber. In certain embodiments, the die tool forms a coating chamber and is configured to apply the coating material on at least one surface of the substrate in the coating chamber.

  • Patent number: 9604251
    Abstract: The present disclosure relates to polymer coating compositions that comprise at least one thermoplastic resin, at least one opacity modifier, at least one gloss modifier, and at least one impact modifier, articles at least partially coated with the polymer coating composition, paintable polymer coated articles and method for making the polymer coated and painted polymer coated articles. These compositions exhibit enhanced paintability (including paintability with water-based paints) and mechanical properties for fabrication (cutting, nailing, routing, etc.), while maintaining acceptable visual appearance, such as, for example, opacity, gloss, surface appearance, and surface roughness.

  • Patent number: 8734909
    Abstract: Methods and apparatus for coating substrates. A die can be employed for extrusion coating an elongated substrate, where the die defines a coating cavity therein. The die can comprise a die block having a coating supply channel for supplying a coating material to the coating cavity. The die can further comprise a guide plug and a die plate removably coupled to the die block. The guide plug can comprise a substrate inlet having a non-circular lateral cross-section, and the die plate can comprise a substrate outlet also having a non-circular lateral cross-section. A coating system comprising such a die can operate to coat a substrate where the substrate can be pushed at least partially through the die and contacts the coating material therein.
