  • Patent number: 11917802
    Abstract: Thermoplastic compounds in the form of a pellet include thermoplastic resin and conductive fibers. The conductive fibers are enveloped by the thermoplastic resin and distributed within the pellet such that each of at least a portion of the conductive fibers is substantially surrounded by the thermoplastic resin and thereby substantially separated from physical contact with any other of the conductive fibers. Additionally, at least a portion of the conductive fibers includes long fibers. The thermoplastic compound, when molded at a thickness of about 3.2 mm, has an electromagnetic shielding effectiveness across a range of frequencies from about 0.5 GHz to about 2.0 GHz of at least about 60 dB according to ASTM D4935, which makes the thermoplastic compound useful for molding thermoplastic articles for shielding against electromagnetic interference.

  • Publication number: 20150210587
    Abstract: A method of forming a coated glass substrate is described, which involves: (a) applying a first composition that includes a hydrolysable silane to a surface of a glass substrate, thereby forming a treated surface of the glass substrate; (b) applying to the treated surface a second composition that includes a fluorinated polyether modified silane, thereby forming an intermediate coated glass substrate; and (c) subjecting the intermediate coated glass substrate to elevated temperature, thereby curing the second composition and forming the coated glass substrate. The method of the present invention results in the formation, with some embodiments, of coated glass substrates that possess anti-fouling properties.
