The present disclosure relates to extrusion-coated structural systems including at least one extruded profile member coupled to and extending outwardly from an extrusion-coated structural member, as well as methods of making and using the same. Structural systems of the present invention that include at least one extruded profile member may exhibit enhanced flexibility, functionality, and/or durability. 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.

Extrusion-coated structural members having extruded profile members

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.

Thermoplastic formulations for enhanced paintability, toughness and melt processability

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.

Methods and apparatus for coating substrates

Disclosed are oriented, shaped articles such as, for example, film, fibers, bottles, and tubes, with excellent strength, toughness, clarity, chemical resistance, and UV resistance. The articles can be prepared from cycloaliphatic polyesters and from compositions comprising cycloaliphatic polyesters and cycloaliphatic polyester elastomers. The articles may be oriented by stretching in at least one direction and have a modulus which results in a soft feel. Also disclosed are polyester compositions comprising cycloaliphatic polyesters and polyester elastomers.

Shaped articles from cycloaliphatic polyester compositions

In a process for producing a profile by profile extrusion of a thermoplastic resin, a melt of the thermoplastic resin is extruded through a die to form the profile. The process is improved by utilizing a thermoplastic resin having a composition of from about 99.95 to about 98.0 weight percent amorphous or semicrystalline polyester and from about 0.05 to about 2.0 weight percent of a zinc salt of an organic acid. The improvement of the process is either by increasing speed or decreasing temperature of a profile extrusion process already operating at a maximum speed and/or temperature with experiencing melt fracture. When melt fracture is present in the profile extrusion process, a method for reducing melt fracture in a profile is accomplished by combining from about 99.95 to about 98.0 weight percent amorphous or semicrystalline polyester and from about 0.05 to about 2.0 weight percent of a zinc salt of an organic acid to form a melt, extruding the melt through an orifice of a die at a temperature and a speed to form an extruded article having a shape, and thereafter quenching the extruded article to form a profile.

Disclosed is a concentrate useful as an additive in a polyester composition comprising a polyolefin and a polyfunctional carboxylic acid or polyol branching agent. Also disclosed is a method of preparing a polyester composition having increased melt viscosity and melt strength, and improved impact strength which comprises the steps of A) melt compounding a polyolefin and a polyfunctional carboxylic acid or polyol branching agent, B) dry blending the melt compounded mixture formed in A) with a polyester, and C) molding or extruding the dry blended mixture formed into B) to form an article.

Concentrates for improving polyester compositions and method of making

Disclosed is a process for forming a layered structure of metal sheet and polyester by heating the metal sheet, extrusion coating a thin layer of polyester on at least one side of the metal sheet, passing the coated sheet through nip rolls and optionally quenching the coated sheet to ensure the polyester coating(s) is in an amorphous state.
