Robert M. Wigdorski has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9512340
    Abstract: An actinic radiation activated, thermally curable solid film adhesive is disclosed that includes a film forming polymeric binder, a cationically curable resin, and a cationic photoinitiator. The solid film adhesive is capable of being processed at temperatures up to 120° C. prior to exposure to actinic radiation without curing, has a latency period at room temperature following activation of the initiator, and is curable at temperatures above 50° C. following activation of the initiator.
    Type: Grant
    Filed: December 11, 2013
    Date of Patent: December 6, 2016
    Assignee: Adhesives Research, Inc.

  • Patent number: 6686425
    Abstract: A high Tg acrylic polymer is provided as well as an epoxy-blend thereof for use as a pressure sensitive adhesive. The high Tg acrylic polymer comprises a copolymer of an alkyl (meth)acrylate monomer whose homopolymer has a Tg>20° C., optionally a C1-30 (meth)acrylate monomer, an nitrogen-containing polar monomer, and a polymerizable epoxy-containing monomer, with the monomers being present in an amount such that the copolymer has a Tg>50° C. When blended with at least one liquid epoxy resin, the resulting mixture exhibits desirable pressure sensitive adhesive properties and may be cured.
