Daniel J. Casper 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).

  • Compositions with improved adhesion to low surface energy substrates
    Patent number: 7671134
    Abstract: Acrylic-based pressure sensitive adhesives are modified with a telechelic hydrocarbon oligomer. The oligomer comprises a hydrocarbon polymer chain or backbone and a functional end group, e.g., an oligomer prepared from a mono hydroxyl polybutadiene polymer and toluene diisocyanate. The oligomer attaches to the acrylic backbone of the polymer as a pendant group and in a preferred embodiment, the oligomer is mixed with the PSA shortly before the PSA is coated.
    Type: Grant
    Filed: November 15, 2006
    Date of Patent: March 2, 2010

  • Acrylic Block Copolymers as Acoustical and Vibrational Dampening Material for Use in Electronic Devices
    Publication number: 20080194759
    Abstract: An electronic device comprises a pressure sensitive adhesive comprising a block copolymer comprising at least one block of a poly(alkyl(meth)acrylate), e.g., poly(methyl(meth)acrylate), and at least one block of a poly(alkylacrylate), e.g., poly(butylacrylate). The adhesive can further comprise a tackifier, e.g., a rosin ester.

  • Label for use on rubber products
    Patent number: 6358605
    Abstract: Labels comprising (i) a film substrate, e.g., polyester, (ii) a primer layer, e.g., resorcinol-formaldehyde resin, and (iii) a pressure sensitive adhesive, e.g., a natural or synthetic rubber based adhesive, are improved by including a second primer layer of chlororesorcinol between the film substrate and the first primer layer.
