Overview: Advantages of Cerakote over Teflon®
Cerakote, a ceramic-based coating, was developed for exceptional resistance to corrosion, abrasion, and chemicals, making it the first choice for industries requiring long-term protection. In contrast, Teflon and Xylan, both fluoropolymer-based coatings, offer non-stick and low-friction properties but may be insufficient for extreme corrosion resistance, especially under highly abrasive or high-temperature conditions. Understanding these differences is crucial for selecting the best coating for specific applications.

Corrosion protection: Cerakote, Xylan®, and Teflon® in direct comparison
In coastal and offshore environments, corrosion protection and performance are crucial for components such as fasteners, bolts, and threads. These applications require both low friction and excellent corrosion resistance. Having recognized Cerakote as a powerful alternative to PTFE coatings, we rigorously compared our product with other industry-standard coatings. Additionally, we offer the F-Series – our PFAS-free ceramic coatings – designed for mass production and manufacturing, available in colors comparable to Xylan.
The Cerakote E-100 Blackout coating was tested for corrosion resistance in a direct comparison with the coatings Teflon® Black 958G, Teflon® Metallic Black 420G, and Xylan® 142X, which are used in marine applications to protect against corrosion. All coatings were applied to plain steel bolts and galvanized nuts to increase the galvanic corrosion rate.
The analysis was conducted in a Q-Fog salt spray chamber according to ASTM B117 and evaluated for corrosion degree using ASTM D610. All coatings were applied to bolts and hex nuts commonly used in industrial marine environments. Cerakote's standard for corrosion failure is rust grade 5-G, 3% rust.
Teflon® Metallic after 24 hours.
Analysis after 48 hours
After 48 hours, both Teflon® grades had exceeded the 3% failure standard on the pin body. The Teflon® pins were removed from the chamber after 640 hours with 100% corrosion.
Xylan® coated bolts after 530 hours.
Results after 530 hours
The Xylan® coated bolts reached the 3% failure standard after 530 hours in the chamber. These samples were removed from the chamber after 1,871 hours with approximately 60% corrosion.
Cerakote E-100 Blackout after 3,963 hours.
3.963 hours comparison
In contrast, the Cerakote Blackout bolts had not yet reached the failure standard after 3,963 hours.
Final results
The test was ended after 4,008 hours because Cerakote Blackout had not yet reached the 3% failure standard. Data analysis showed that Cerakote Blackout has 99% better corrosion resistance than Teflon® and 87% better corrosion resistance than Xylan®.
Cerakote E-100 Blackout surpasses the corrosion protection of the leading competitor by more than 3,470 hours. Cerakote is committed to providing the industry with superior coating solutions regardless of the application. This test demonstrates that Cerakote is the coating of choice when corrosion protection matters.
