Overview: Advantages of Cerakote over Teflon®
Cerakote, a ceramic-based coating, is engineered for exceptional resistance to corrosion, abrasion, and chemicals, making it a premier 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 fall short in extreme corrosion resistance, particularly under highly abrasive or high-temperature conditions. Understanding these distinctions is crucial for selecting the best coating for specific applications.

Corrosion Protection: Cerakote, Xylan®, and Teflon® in a 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. Recognizing Cerakote as a high-performance alternative to PTFE coatings, we have rigorously compared our product to other industry-standard coatings. Additionally, we offer the F-Series – our PFAS-free ceramic coatings – engineered for mass production and manufacturing, available in colors comparable to Xylan.
Cerakote E-100 Blackout coating was tested for corrosion resistance in direct comparison to Teflon® Black 958G, Teflon® Metallic Black 420G, and Xylan® 142X coatings, which are used in marine applications for corrosion protection. All coatings were applied to plain steel bolts and galvanized nuts to accelerate the galvanic corrosion rate.
The analysis was performed in a Q-Fog salt chamber in accordance with ASTM B117 and evaluated for degree of corrosion 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 bolt body. The Teflon® bolts 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 concluded after 4,008 hours with Cerakote Blackout still not reaching the 3% failure standard. Data analysis revealed that Cerakote Blackout exhibited 99% better corrosion resistance than Teflon® and 87% better corrosion resistance than Xylan®.
Cerakote E-100 Blackout outperforms the leading competitor’s corrosion protection by more than 3,470 hours. Cerakote is committed to providing superior coating solutions to industries, no matter the application. This test demonstrates that Cerakote is the coating of choice when corrosion protection is paramount.
