Test Data on our Various Ceramic Base Exhaust Coating

The unique, ceramic-based formulation used in the entire line of Cerakote TM. Exhaust coatings enhances a number of physical characteristics. Cerakote TM. Exhaust coatings are durable, heat-resistant coatings with excellent long-term performance. Additionally, Cerakote TM. Ceramic exhaust coatings function as thermal barriers for thermally-sensitive applications. This report outlines the different high-temperature coatings available from Cerakote TM. And discusses the properties inherent to each. The thermal barrier capability and chemical resistance of each coating was also studied, and the results of this study are published in this paper.

Thermal Barrier Testing

Four different Cerakote TM. Products were tested to determine the potential of each as a thermal-barrier coating. These for coatings are shown in table 2 with their respective properties. Each of these coatings were used to coat a 3' long section of pipe. The pipes were manufactured of cold-rolled steel and had an inner diameter of 2”. The pipes were cured according to the appropriate cure schedule and then horizontally mounted using 2 clamps spaced 6” from the center of each pipe. Three thermocouples, one in the center, one 3” from the inlet and one 3” from the outlet, were positioned on each pipe. Each thermocouple was held in place using a band clamp. A gas burner was attached to the inlet side of each pipe and the pipes were heated according to the following program:

  • Start condition: Ambient air at 100 SCFM
  • Ramp to 572°F in 1 minute, hold for 10 minutes
  • Ramp to 1112°F in 1 minute, hold for 10 minutes
  • Ramp to 1760°F in 1 minute, hold for 10 minutes

The air flow rate was maintained at 100 SCFM for the duration of the test. The inlet gas temperature and the temperatures recorded by the 3 skin thermocouples were also monitored and recorded at 1 second intervals.

Conclusion:

The results of this test are illustrated in figure 1 above. At temperatures below 572°F, C-7300 Black Velvet performed the best. Above 572°F V-171 Turbine Coat provided the most thermal protection. At 572°F, using C-7300 Black Velvet as a thermal barrier resulted in a 110°F drop in outer skin temperature. At 1112°F and 1760°F, V-171 Turbine Coat resulted in a 102°F and 185°F drop, respectively.

Due to variations in monitors and printers, colors may vary. Ask for hard sample if color is critical.
