  • Patent number: 10626098
    Abstract: Copoly(imide oxetane) materials are disclosed that can exhibit a low surface energy while possessing the mechanical, thermal, chemical and optical properties associated with polyimides. The copoly(imide oxetane)s are prepared using a minor amount of fluorinated oxetane-derived oligomer with sufficient fluorine-containing segments of the copoly(imide oxetane)s migrate to the exterior surface of the polymeric material to yield low surface energies. Thus the coatings and articles of manufacture made with the copoly(imide oxetane)s of this invention are characterized as having an anisotropic fluorine composition. The low surface energies can be achieved with very low content of fluorinated oxetane-derived oligomer. The copolymers of this invention can enhance the viability of polyimides for many applications and may be acceptable where homopolyimide materials have been unacceptable.

  • Patent number: 10220594
    Abstract: Hydrophobic thermal insulation fiberglass flexible blanket using a textile grade fiberglass is produced by impregnating a hydrophobic polymer (e.g. a fluoropolymer) dispersion into a fiberglass blanket/mat, such as a needle felted fiberglass (FG) blanket/mat. The preferred FG needle felt blanket is a mechanically, rather than organically, bound glass fiber insulating blanket. The hydrophobic polymer dispersion forms a hydrophobic coating on the surface of the fiberglass filaments. Integral hydrophobicity is achieved and maintained without the need to add commonly-used hydrophobic inorganic particles, such as treated silica aerogels or fumed silica. Optionally, to enhance overall hydrophobicity and to inhibit fibrous surface lofting, a super-hydrophobic coating of fluoropolymer and inorganic particles such as silica particles may be dispersed onto one or more surfaces of the blanket.

  • Patent number: 9067237
    Abstract: A coated part includes a metal substrate having a surface area with a first region and a second region. A first cured coating of a first ceramic material is located on the first region of the substrate, and a second cured coating of a second ceramic material is located on the second region of the substrate. The first coating and the second coating are different in appearance and are free of pinholes, blistering, flaking, and peeling. The first and second coatings abut one another on the substrate, with no gap between them to expose the substrate, and neither of the first coating or the second coating overlaps with the other coating on the substrate. One of the coatings may include a metallic component. At least one of the coatings requires exposure to a temperature of at least 500° and in many cases 650° Fahrenheit to cure on the substrate.

  • Publication number: 20150118439
    Abstract: A robotic electrostatic painting system includes a barrier formed from an electrical insulating material and disposed between adjacent reservoirs for holding a conductive paint used in an electrostatic painting operation. The barrier is shaped and dimensioned with a central plate and upper and lower flanges to block every straight line path between the reservoirs to electrostatically separate the reservoirs and prevent the formation of a ground path or short circuit when there is a voltage difference between the reservoirs. The electrostatic separation of the reservoirs further prevents deterioration of conductive components of the robotic electrostatic painting system.

  • Publication number: 20150111013
    Abstract: Provided is an a aramid-resin film laminate comprising an aramid paper comprising an aramid fibrid and an aramid short fiber, and a resin film laminated on each other. The aramid-resin film laminate is obtained by conducting a plasma treatment on a surface of the aramid paper, the surface having a skin layer portion whose heat of fusion measured with a differential scanning calorimeter (DSC) is 25 cal/g or less, and bonding the aramid paper and the resin film to each other by heating, pressing, or heating under pressure, with the plasma treated surface of the aramid paper and a plasma treated surface of the resin film facing each other. This laminate is an aramid-resin film laminate in which the aramid paper and the resin film are laminated on each other without using any adhesive agent and without impairing characteristics of both the aramid paper and the resin film, and is excellent in heat resistance, electrical characteristics, chemical resistance, mechanical characteristics, and the like.
