Teflon coatings can be applied to a wide variety of materials, including metals such as carbon steel, stainless steel, aluminum, copper, magnesium, and various alloys, as well as non-metallic materials like glass, fiberglass, and certain rubber plastics. These coatings are particularly beneficial when applied to stud bolts, nuts, and other fasteners, providing enhanced performance in demanding environments.

Product Features

1. Non-Stick

The Teflon coating's low surface tension gives it excellent non-stick properties, making it difficult for solid substances to adhere to the surface. This is especially advantageous for stud bolts and nuts, as it reduces the accumulation of debris and prevents the seizing of fasteners, ensuring easy assembly and disassembly.

2. Low Friction Coefficient

Teflon boasts one of the lowest friction coefficients among solid materials, ranging from 0.05 to 0.2 depending on factors like external pressure, sliding speed, and coating type. This characteristic minimizes wear on stud bolts and nuts, extending their lifespan and ensuring smooth operation under high-torque conditions.

3. Non-Wettability

The hydrophobic and oil-repellent nature of the Teflon coating ensures that liquids, oils, and chemicals slide off the surface, preventing corrosion and ensuring that stud bolts and nuts remain clean and functional over extended periods of use.

4. High Surface Resistance

Through special formulations or industrial treatment, Teflon coatings can be engineered to possess certain conductivity, making them ideal for use as anti-static coatings on stud bolts and nuts in environments where electrostatic discharge (ESD) protection is needed.

5. High Temperature Resistance

Teflon coatings are highly resistant to high temperatures, with a working temperature of up to 290°C and intermittent service up to 315°C. This makes them ideal for stud bolts and nuts used in high-heat applications, ensuring durability and preventing degradation under extreme thermal conditions.

6. Chemical Resistance

Teflon is highly resistant to most chemicals, making it an ideal choice for stud bolts, nuts, and other fasteners exposed to harsh chemical environments. The coating protects against corrosion and wear caused by aggressive substances, with the exception of molten alkali metals and fluorinating agents at high temperatures.

7. Low Temperature Stability

Teflon coatings maintain their mechanical properties even at extremely low temperatures, as low as -270°C/-454°F. This feature is especially useful for stud bolts and nuts used in cryogenic or low-temperature environments, ensuring reliable performance and maintaining tight seals in challenging conditions.
