Patent number: 8017531Abstract: A composite material comprising a substrate having an ionic charge which is coated with a coating having essentially the same ionic charge and a metallic component adhered on one or both sides of the coated substrate. The coating consists essentially of a filler material comprising clay and a binder material. The substrate is preferably fiberglass, the filler material may further comprise at least one additional filler selected from the group consisting of decabromodiphenyloxide, antimony trioxide, fly ash, charged calcium carbonate, mica, glass microspheres and ceramic microspheres and mixtures thereof and the binder material is preferably acrylic latex. The metallic component is preferably aluminum foil. The composite material has heat insulating and fire resistant characteristics.Type: GrantFiled: January 27, 2004Date of Patent: September 13, 2011Assignee: ElkCorpInventors: Younger Ahluwalia, Matti Kiik, Thomas D.

Publication number: 20110136400Abstract: The present invention relates to a vapor-pervious water-impervious substrate, preferably a fibrous nonwoven web, which can be used in particular as a textile continuous sheet material, for example as an awning or as an inlet in apparel. The substrate according to the present invention may have self-cleaning properties. The substrate according to the present invention is simple to produce in an at least two-step process wherein a coating on the fibers of the substrate is produced in the first step and then hydrophobic particles are applied to the coated fibers by means of an adhesion promoter.Type: ApplicationFiled: November 3, 2010Publication date: June 9, 2011Applicant: DEGUSSA AGInventors: Volker HENNIGE, Christian HYING, Gerhard HÖRPEL, Markus OLES, Edwin NUN, Bernhard SCHLEICH

Publication number: 20110021098Abstract: A method is described for manufacturing a finish formulation for the hydrophobic and/or oleophobic finishing of surfaces, comprising a dispersant incorporating dispersed, activated particles with hydrophobic and/or oleophobic surface groups and a binder, in which particles with hydrophobic and/or oleophobic surface groups are comminuted in the dispersant for activation, and the binder is added before or after activation. The obtained finish formulation clearly improves the physical properties of a transparent finish while maintaining very good hydrophobing/oleophobing. It is suitable for finishing all surfaces, in particular for finishing fibers or textiles of all kinds.Type: ApplicationFiled: October 23, 2007Publication date: January 27, 2011Applicants: Bühler Partec GmbHü, Schoeller Textil AGInventors: Frank Tabellion, Klaus Steingröver, Peter Waeber, Roland Lottenbach

Publication number: 20100323572Abstract: The present invention relates to fire resistant composite materials and to fire resistant fabric materials and mattresses made therefrom. The composite materials include (a) a substrate selected from the group consisting of cotton, rayon, lyocell and blends thereof; and (b) a coating consisting essentially of water, ammonium polyphosphate, binder material, cross-linking material, thickener material and a catalyst. The binder material bonds the ammonium polyphosphate, cross-linking material, thickener material and catalyst together and to the substrate such that the substrate is coated with the coating.Type: ApplicationFiled: August 30, 2010Publication date: December 23, 2010Applicant: Building Materials Investment Corp.Inventor: Younger Ahluwalia
