Patent number: 6406782Abstract: A multi-layer article which may be provided in the form of a tape comprises a conformable, compressible, melt flow-resistant core layer having first and second major surfaces, a sealant layer on the first major surface of the core layer, and optionally a bonding layer on the second major surface of the core layer. The sealant layer and the bonding layer each have a surface available for contacting a separate substrate. Various thermoset and foam core layers are disclosed as are thermosettable and thermoplastic sealant layers. The articles are useful for sealing two substrates together, particularly where one of the substrates is glass. Thus, the articles are especially adapted for sealing motor vehicle windshields to a frame. Various assemblies and methods for producing the same are also described.Type: GrantFiled: June 29, 2001Date of Patent: June 18, 2002Assignee: 3M Innovative Properties CompanyInventors: Michael A. Johnson, Clayton A. George, Robert J. Boettcher

Patent number: 6325969Abstract: The present invention provides a porous paper product impregnated with at least one chemical species. The porous paper product can be in the form of sheets, or compressed pellets. The porous paper can be prepared from a variety of sources, including wood pulp, kenaf, flax, or hemp. The chemical species impregnating the paper react and/or diffuse out of the paper to accomplish a variety of desired results. For example, diffusion of a volatile biocidal chemical out of pores in the paper create a no-growth zone on and immediately surrounding the impregnated paper. In this manner the impregnated paper can provide a sterile environment for activities such as food packaging/storage, the treatment of illness/injury, or waste disposal.Type: GrantFiled: April 30, 1999Date of Patent: December 4, 2001Inventors: James Aamodt, John Colvin

Patent number: 6265058Abstract: The present invention is a dielectric film, and method for making the film, suitable for use in the construction of capacitor devices, including wound capacitors. In order to overcome strength limitations associated with polymers having desirable dielectric properties, the invention includes a dielectric film featuring a polymer impregnated upon a strengthening substrate. The polymer is deposited directly upon the substrate, which substrate provides required physical strength for film processing and capacitor fabrication, without compromising dielectric performance. The inventive film is based on siloxane polymers modified with polar pendant groups to provide a significant increase in dielectric constant and dielectric strength. During film production, the polymer infiltrates the porous paper to provide an interfacial composite layer between the two materials, the interfacial layer consisting of polymer and paper.Type: GrantFiled: March 5, 1999Date of Patent: July 24, 2001Assignee: TPL, Inc.Inventors: Kirk M. Slenes, Kristen J. Law, William F. Hartman
