  • Patent number: 6638882
    Abstract: The present invention relates to methods of preparing improved fiber glass compositions using an improved resin binder. The resin binder comprises an aqueous solution of a resole resin, a catalyst comprising an ammonia salt of an aryl sulfonic acid, and optional binder modifiers. It has been found that the use of ammonium aryl sulfonate salts in resin binder compositions, as in the present invention, provides an enhanced cure rate and also enables manufacture of a fiber glass composition exhibiting enhanced uncured storage properties, increased thermal stability, and reduced corrosiveness to metals.

  • Patent number: 5601629
    Abstract: A fiberglass product usable as an end product or an intermediate product is formed as a pack in a forming station but only 1/7th of the conventional quantity of binder is applied. After curing to a self-sustaining form, additional binder is added in an amount in excess of the amount required in the final product and then the excess binder and moisture is removed by one or more stripping steps. Additional moisture is removed by electronic means to the desired moisture level for commercial products.
    Type: Grant

    Date of Patent: February 11, 1997
    Inventor: Clarence H. Helbing
  • Patent number: 5324337
    Abstract: A fiberglass product usable as an end product or an intermediate product is formed as a pack in a forming station but only 1/7th of the conventional quantity of binder is applied. After curing to a self-sustaining form, additional binder is added at a location remote from the forming station in an amount in excess of the amount required in the final product and then the excess binder and moisture is removed by one or more vacuum stripping steps.
    Type: Grant
    Filed: December 29, 1992
    Date of Patent: June 28, 1994
    Assignee: Knauf Fiber Glass GmbH
    Inventor: Clarence H. Helbing
  • Patent number: 4392900
    Abstract: A method for applying an elastomeric patch to a polypropylene or polyethylene battery case including the steps of cleaning the surface area with a solvent, applying hydrogen peroxide to an abrasive material, such as emery cloth, abrading away the surface layer, and applying the patch to the prepared surface by means of a cyanoacrylate adhesive.
