  • Spark plug insulator having an anti-fouling coating and methods for minimizing fouling
    Patent number: 9548591
    Abstract: An insulator for a spark plug comprises a first segment surrounding the terminal, a second segment extending from the first segment, and a third segment extending from the second segment. A gap is disposed between the third segment of the insulator and the outer shell. At least one coating having a least one layer is disposed on a surface of the third segment.
    Type: Grant

  • Method of applying a coating to a spark plug insulator
    Patent number: 9337627
    Abstract: A method of applying a coating to a spark plug insulator comprises the steps of forming a slurry solution and applying the slurry solution as a first coating to an insulative sleeve configured for use in a spark plug. The method further includes the step of heat treating the insulative sleeve to a temperature of between about 500 degrees Celsius and about 1000 degrees Celsius for between about 10 minutes and about 2 hour(s). Still further, the method includes the step of applying a second coating overlying at least a portion of the first coating, wherein the second coating comprises an organic binder.
