Patents by Inventor Christopher Swech

Christopher Swech 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: 11597838
    Abstract: Polymers are disclosed that incorporate portions of secondary or tertiary polyamide segments connected with polyisocyanates. These polymers have enhanced matting properties. The enhanced matting properties are from creating an inherently matt surface from the polymer without the use of any separate fine particle size matting additives. Conventional matting agents such as fine particle size silica usually results in loss of physical properties such as haze development and porosity in the coating from the matting agent. Composites and hybrids of these polymers and other polyamides, polyurethane with vinyl polymers (acrylates) are also disclosed and claimed.
    Type: Grant
    Filed: May 6, 2022
    Date of Patent: March 7, 2023
    Assignee: Lubrizol Advanced Materials, Inc.

  • Publication number: 20220220248
    Abstract: The present invention relates to thermoset polymer solution, such as a polyurethanes and/or polyureas that include sufficient polyamide to give polyamide strength, adhesion, and durability, wherein the polymer solutions can be prepared as a one-component or two component solvent-borne coating composition. The polyamides give a harder, more chemical resistant, and often tougher thermoset, than similar water-borne polyurethanes rich in polyamide. The compositions of this disclosure differ from other polyamides as they have been formulated to be appropriate viscosity to use as coatings and then have crosslinking technology to form hard thermoset films.
