  • FLUOROPOLYMER STRUCTURES
    Publication number: 20170009000
    Abstract: Fluoropolymer structures are provided for use in aircraft interiors. The structures include an external cross-linked fluoropolymer layer that is lighter and safer than conventional fluoropolymer film layers. In general these structures can be described as a panel for the interior of an aerospace vehicle made of an aluminum or fiber composite facesheet, a foam or honeycomb core attached to the facesheet, and a layer of cross-linked fluoropolymer on the surface of the facesheet that is on the side facing away from the core. Methods of making and using the structures are also provided.

  • Method for producing low sheet gloss coated paper
    Patent number: 4751111
    Abstract: The improvement in the production of low sheet gloss coated papers which comprises using as the synthetic polymer latex binder for the aqueous coating composition employed to coat the papers, a carboxylated latex which substantially swells during the preparation of the aqueous coating composition and subsequently shrinks during the drying of the coated paper, whereby a microscopic surface roughness is obtained to yield a low sheet gloss coated paper while retaining high ink gloss.
