Henry G. Barnowski, Jr. 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).

  • Low viscosity polyuretidione polyurethanes and their use as curatives for solvent and water borne coatings
    Patent number: 5861193
    Abstract: The present invention relates to the preparation and use of novel polyurethane polyuretidione crosslinking agents in solvent and water borne coatings systems. These polyuretidione polyurethanes are characterized by their relatively low solution viscosity, and the ability to provide a relatively high crosslink density in the final, cured film, and thereby, coatings with the excellent physical properties and resistance to chemical and environmental exposure of known polyurethane systems without the potential for worker exposure to toxic isocyanates. This invention also relates to a process for the production of these polyuretidiones and their use in pseudo-one and two component coating compositions.

  • Bis(isobutyraldimine) of 1,4-diaminobutane in HDI trimer and biuret-based coatings
    Patent number: 5856420
    Abstract: Disclosed are new coatings compositions based on an HDI isocyanurate or biuret polyisocyanate and a bis(imine) reaction product of a diaminoalkane containing between two and five carbon atoms with an alkyl aldehyde containing between four and seven carbon atoms (advantageously a bis(imine) product of the reaction of 1,4-diaminobutane and isobutyraldehyde). The latter bis(imine) is completely miscible in HDI isocyanurate and biuret polyisocyanates, and, as a reactive diluent, allows the preparation of high performance coatings formulations that require only small amounts of solvents to achieve a conveniently sprayable viscosity.
