Publication number: 20110024933Abstract: A carrier-free expandable filler insert for filling or sealing a hollow space or cavity is provided. The insert comprises a self-supporting continuous structure that may be produced by contour extrusion molding or injection molding a polymer matrix containing a polymer and/or polymer precursor and a latent blowing agent. The expandable filler insert is secured to the interior surface of a vehicle pillar, for example, using a fixing element that may be integral with the self-supporting continuous structure, the polymer matrix thereafter being activated and expanded by heating.Type: ApplicationFiled: May 27, 2009Publication date: February 3, 2011Applicant: Henkel AG & Co, KGaAInventors: Jean-Pierre Monnet, Delphine LeClerc, Gregory Magnet, Karl Wesch, Daniel Rudolph, Matthias Jähnichen

Patent number: 7238407Abstract: Multi-layer laminates are provided which contain at least two binder layers and at least two textile-containing layers. One binder layer faces a substrate to be reinforced, with a second binder layer between two textile-containing layers wherein one of the textile-containing layers is interposed between the binder layers. The binder layer facing the substrate has an elasticity modulus when cured which is less than or the same as the elasticity modulus of the second binder layer. The laminates are suitable for reinforcing or stiffening planar substrates, especially thin-walled substrates such as motor vehicle body parts.Type: GrantFiled: April 18, 2005Date of Patent: July 3, 2007Assignees: Henkel Kommanditgesellschaft Auf Aktien, Dr. Ing. H.C.F. Porsche AktiengesellschaftInventors: Karl Wesch, Matthias Jaehnichen, Adriano Morozini De Lira, Juergen Durm, Dietger Frisch

Patent number: 7140668Abstract: A molding is described, the outer edge region of which comprises a thermally expandable material that has a high coefficient of friction in relation to metal or plastic. In its inner region this molding has an aperture and/or recess for receiving a mounting aid. The molding is suitable as a sealing and acoustically active bulkhead part and with the aid of friction forces can be fixed mechanically in the cavity of structural components without these components having to exhibit bores, apertures or other devices for fixing the bulkhead part.Type: GrantFiled: February 24, 2005Date of Patent: November 28, 2006Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Karl Wesch, Ralph Dalhaeuser

Publication number: 20030207026Abstract: A composition for spray coating metal parts for protection and sealing. The composition is a water, volatile organic solvent and liquid plasticizer free thermoplastic powder composition having a particle size below 700 &mgr;m. A portion of the polymers carry polar functional groups.Type: ApplicationFiled: April 30, 2003Publication date: November 6, 2003Inventors: Karl Wesch, Hanno-Martin Becker, Dirk Reitenbach

Patent number: 6559213Abstract: Monoesters of fatty acids containing at least 12 carbon atoms may replace a considerable percentage of conventional plasticizers based on phthalic acid esters, alkyl sulfonic acid esters of phenol or other known plasticizers in plastisol compositions. The methyl and/or ethyl esters of fatty acids of renewable fats and oils, such as tall oil fatty acids, rapeseed oil fatty acids, linseed oil fatty acids or safflower oil fatty acids, are preferably used for these secondary plasticizers. These plastisols are preferably used as adhesives, sealing materials or coatings in automobile construction.Type: GrantFiled: May 15, 2001Date of Patent: May 6, 2003Assignee: Henkel-Teroson GmbHInventor: Karl Wesch

Patent number: 5756555Abstract: Plastisol compositions based on vinyl chloride/vinyl acetate copolymers produced by suspension polymerization have a low viscosity, even with low polymer-to-plasticizer ratios, so that they may be used for plastisol formulations suitable for airless spraying. The compositions are stable in storage and show good gelation properties. Coatings based on these plastisols have a good noise-damping effect, even with high vinyl acetate contents.Type: GrantFiled: December 20, 1996Date of Patent: May 26, 1998Assignee: Henkel Teroson GmbHInventors: Karl Wesch, Klaus Ruch

Patent number: 5633305Abstract: Coating compositions based on waxes, wax-like compounds, drying oils or alkyd resins are improved in their running behavior by the addition of additives which gel at elevated temperature. Other positive properties of the coating compositions, such as for example wetting, penetration (creepage), sprayability, are not adversely affected.Type: GrantFiled: June 5, 1995Date of Patent: May 27, 1997Assignee: Teroson GmbHInventors: Karl Wesch, Dieter Stamm, Dirk Reitenbach, Winfried Schwittay
