David T. Thrane 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).

  • Acrylic and acrylic/epoxy copolymer composition as self-curing cathodic electrocoating vehicles
    Patent number: 4742097
    Abstract: Package and tank stable low temperature self-curing cation-active aqueous soluble or dispersible coating compositions are prepared by polymerizing blocked isocyanatoethyl methacrylate (IEM) alone or copolymerizing with various vinyl unsaturated monomers optionally in the presence of epoxy-amine adduct. These cation-active polymers when acidified or partially acidified provide aqueous solutions or dispersions especially useful as low temperature curable vehicles in cathodic electrocoating.
    Type: Grant
    Filed: October 29, 1986
    Date of Patent: May 3, 1988
    Assignee: The Glidden Company
    Inventors: Edward T. Turpin, David T. Thrane
  • Self-curable benzoxazine functional cathodic electrocoat resins and process
    Patent number: 4719253
    Abstract: New aqueous dispersible cathodic electrocoat resin compositions containing both secondary amine and 1,3-benzoxazine functionality cure by oxazine self-additon and/or oxazine/amine reactions. Such compositions are prepared in a multi-stage process to give corrosion and chemical resistant coatings which exhibit good package (tank and feed) stability.

  • Acrylic and acrylic/epoxy copolymer compositions as self-curing cathodic electrocoating vehicles
    Patent number: 4608314
    Abstract: Package and tank stable, low temperature self-curing, cation-active aqueous soluble or dispersible coating compositions are prepared by copolymerizing blocked meta-isopropenyl-.alpha.,.alpha.-dimethylbenzyl isocyanate (m-TMI) with various vinyl unsaturated monomers optionally in the presence of epoxy-amine adduct. These cation-active polymers when acidified or partially acidified provide aqueous solutions or dispersions especially useful as low temperature curable vehicles in cathodic electrocoating.
