Publication number: 20100236708Abstract: Two-component systems are described which are suitable for underlining, adhesive bonding of the crimped fold and sealing of auto body sections, particularly for crimped fold sealing of add-on vehicle parts. The two-component systems attain the requisite grip strength for mounting the add-on parts on the body as well as the requisite strength and dimensional stability for the production process up to and with the CIP passage, within the predetermined cycle time, on the basis of cross-linking of the sealant composition twice. In one embodiment, the surface of the two-component system is pre-cross-linked by a UV-induced reaction and by the cross-linking of the two-component system to the extent of portability. In addition, two-component systems are described which cross-link intentionally only partially up to a consistency that permits a rugged course of the process through cleaning baths and which harden completely only by means of a further hardening process, for instance in the CIP forced circulation oven.Type: ApplicationFiled: September 21, 2009Publication date: September 23, 2010Applicant: Sika Schweiz AAAAGInventor: Peter W.

Patent number: 6875470Abstract: Novel undercoats for use on porous bases such as, for example, concrete are disclosed. Said undercoats contain or comprise at least one epoxy resin, at least one latent hardener and at least one solvent. The above are characterize in being easy to produce, contain no isocyanate groups and form a good ageing-resistant adhesion, in particular, with single component isocyanate-free sealants, cross-linked by means of silane groups.Type: GrantFiled: November 28, 2001Date of Patent: April 5, 2005Assignee: Sika Schweiz AGInventors: Gerald Trabesinger, Peter W.

Patent number: 6797099Abstract: A new method for the bonding of painted construction parts, in particular for the structural bonding of painted metals surfaces is described. In a first step of the inventive method, a carcase work adhesive is applied onto all parts of the oiled steel sheet on which later on, during assembly, bonding shall be performed. For the bonding, the lacquer layers on the carcase work adhesive are removed prior to the application of an assembly adhesive. Said method is simple and rugged. In comparison with the state of the art it is more economic, enables a highly structural and high strength joining with high torsional strength and a high ageing resistant compound quality.Type: GrantFiled: January 24, 2002Date of Patent: September 28, 2004Assignee: Sika Schweiz AGInventor: Peter W.

Patent number: 6696124Abstract: An adhesive compound is described that is formed using a specific adhesive system. Due to the specific adhesive system the disconnecting of the adhesive compound is considerably eased, which, in particular, is of great benefit for the quick removal of plastic windows in case of emergency. The specific properties of the adhesive compound are based on its specific structure. In the middle of the compound between the substrates a specific parting layer is installed by which the two substrates can be disconnected easily. The parting layer preferably is an elastomer that has an extremely high tenacity and an elongation at rupture of 500% up to more than 1500% and that shows a good adherence to the assembly adhesive so that the removal can be performed by stretching the parting layer whereby it constricts and thereby peels off from the adhesive.Type: GrantFiled: September 24, 1999Date of Patent: February 24, 2004Assignee: Sika Schweiz AGInventors: Peter W. Merz, Thomas Wirz, Bernd Rudi Burchardt

Patent number: 6602947Abstract: New primers for the improvement of the adhesion of cross-linking adhesive systems top polyolefinic thermoplastic materials such as e.g., polypropylene, polyethylene or EPDM are disclosed. Said primers, on the one hand are characterized by a simple method of production and good storage stability, on the other hand by good wetting and good homogeneous film forming characteristics, said film forming characteristics enabling a uniform thickness of the layer, leading to good adhesion qualities. Essential constituents of such primers are prepolymers based on hydrogenated polyisoprene diol.Type: GrantFiled: April 30, 2001Date of Patent: August 5, 2003Assignee: Sika Schweiz AGInventors: Peter W. Merz, Shingo Tsuno

Patent number: 6548593Abstract: New thixotropic agents for the use in cross-linking systems, in particular one-component adhesives and sealants, are described. The thixotropic agents have the advantage that on the one hand they cause only a minor or no increase in viscosity, and on the other hand they do not cause any blead out or migration, respectively. The thixotropic agents of the present invention are based on urea derivatives that usually are present in a concentration of 5 to 50 wt.-%, in particular of 15 to 30 wt.-%, in a preferably reactive carrier material. After the cross-linking of the system, the reactive carrier material is incorporated, preferably into the structure matrix, or interwoven with said structure matrix, respectively, such that it can not diffuse out of the cured material.Type: GrantFiled: May 2, 2001Date of Patent: April 15, 2003Assignee: Sika Schweiz AGInventors: Peter W. Merz, Ukiwo Onuoha, Shingo Tsuno

Publication number: 20030051610Abstract: The present invention relates to an adapter (1), an apparatus for and a method of extracting commodities from the pack compartments (28a, 28b) of a multicompartment sausage pack (10) in which the commodities extracted from the compartments (28a, 28b) are led in the adapter (1) separately in separate through flow channels (11a, 11b). By means of this the commodities can be extracted from the compartments of the multicompartment sausage pack in set proportional amounts without a forced intermixing.Type: ApplicationFiled: October 15, 2002Publication date: March 20, 2003Inventors: Roland Dux, Peter W Merz, Stephan Oderbolz

Patent number: 6478915Abstract: A method of sealing body parts such as an edge fold of a motor vehicle component, for example a door, a rear or front flap or a sliding roof panel, includes a two-step pre-cross-linking of the sealing composition in the rough body part. In a first step the surface of a UV-active sealing composition is pre-cross-linked by UV irradiation, and in a second step immediately following, the edge fold adhesive and the sealing composition are hardened by thermal action. The edge-sealed body parts produced by the method are transportable and are of visually and functionally satisfactory quality after passing through cleaning baths and after thermal hardening in a KTL kiln. Since the sealing is carried out in the rough body part rather than during the coating process, the method provides a substantial potential cost saving.Type: GrantFiled: April 3, 2000Date of Patent: November 12, 2002Assignees: Volkswagen AG, Sika AG vorm.

Publication number: 20010053827Abstract: Described are adhesives that in usual climatic conditions are storage stable over a certain period of time and that cure upon the application of an activation step. The inventive adhesives at room temperature have a thermoplasticity similar to butyl rubber and thus are plastically deformable upon joining of construction elements with the pressure necessary for such joining, and do not have a tendency for crack formation. In a lot of cases, said inventive consistency enables direct adhesion without the necessity of mechanical fixation.Type: ApplicationFiled: June 5, 2001Publication date: December 20, 2001Inventors: Peter W. Merz, Michael Gutgsell, Shingo Tsuno
