Static dissipative fuel tank coatings and methods

摘要

There is provided a method for mitigating static discharge in a fuel container. The method provides a static dissipative coating having a volume resistivity of 1.0×109 Ω-m (ohm-meter) or less when measured at 40 V (volts) or less, having a surface resistivity of 1.0×1011 Ω/sq (ohm per square) or less when measured at 100 V (volts) or less, having a breakdown voltage of 4000 V (volts) or less, and having a charge decay of 60 seconds or less. The method further provides applying the static dissipative coating to a surface of the fuel container to form a coated surface.

1. A method for mitigating static discharge in a fuel container, the method comprising:
applying a non-chromated static dissipative coating directly to a surface of the fuel container, the fuel container comprising one or more composite components and one or more metal components, wherein the coating is only applied over the one or more composite components as a topmost layer on the one or more composite components, the static dissipative coating having a volume resistivity of 1.0×109 Ω-m (ohm-meter) or less when measured at 40 V (volts) or less, having a surface resistivity of 1.0×1011 Ω/sq (ohm per square) or less when measured at 100 V (volts) or less, having a breakdown voltage of 4000 V (volts) or less, and having a charge decay of 60 seconds or less.
