PTFE Coating Services
Engineered for extreme conditions, our PTFE coatings offer non-stick protection, low friction, and high resistance to wear and corrosion—ideal for mission-critical performance with streamlined processing.
PTFE (Polytetrafluoroethylene) coatings
PTFE (Polytetrafluoroethylene) coatings are high-performance surface treatments that offer excellent non-stick, chemical-resistant, and low-friction properties. Commonly known by the brand name Teflon®, these coatings are applied to metal and plastic parts to reduce wear, prevent material buildup, and protect against harsh operating conditions.
At Diamond Metal Finishing, we provide precision-applied PTFE coatings tailored for industrial, aerospace, medical, and food-grade applications. Whether you need a dry lubricant, a chemical barrier, or a clean-release surface, PTFE coatings help improve equipment performance and service life—especially in high-temperature, high-friction, or chemically aggressive environments.
PTFE coatings are available in a range of formulations and thicknesses to meet your part geometry, operating conditions, and regulatory requirements. From sliding components to food processing tools, we ensure even coverage, strong adhesion, and dependable results—every time.

Design & Tolerance Best Practices
- Allow for Coating Build-Up
Account for 8–40 microns (0.31–1.57 mils) of coating thickness when designing tight-tolerance components. - Masking Critical Areas
Masking should be planned in advance for threads, grounding points, or no-coat zones. - Uniform Surface Preparation
Ensure all surfaces are clean, dry, and free of oils to promote strong and even adhesion. - Edge Rounding
Sharp edges should be slightly radiused to help prevent coating flaking or uneven application. - Maintain Clearance in Assemblies
Design with proper clearance to avoid interference once coating is applied to mating parts.

Frequently Asked Questions
What is PTFE coating, and how does it work?
PTFE coating is a non-stick, low-friction protective layer applied to metals to resist wear, corrosion, and extreme temperatures.
Is PTFE coating heat resistant enough for Texas summers?
Yes, PTFE can handle temperatures up to 260°C (500°F), making it perfect for the hot Texan climate and industrial ovens.
Will PTFE coatings prevent rusting in high-humidity areas like Houston?
Absolutely. PTFE’s chemical inertness forms a barrier against moisture, air, and chemicals that cause corrosion.
Can PTFE coating be applied to aluminum?
Yes, we coat aluminums.
Is your PTFE coating food-safe and FDA-approved?
Yes, we offer FDA-compliant PTFE coatings that are safe for use in food processing and packaging applications.
How long does a PTFE coating typically last?
It depends on usage, but for most industrial applications, PTFE coatings can last several years without reapplication.
Is PTFE coating safe for electrical components in my equipment?
Yes, PTFE has excellent dielectric properties, making it suitable for insulating sensitive electrical or electronic parts.
Can PTFE handle oilfield or petrochemical exposure common in Texas industries?
Definitely. PTFE is chemically resistant and performs well in harsh environments, including oil, gas, and chemical industries.
How thick is the PTFE coating you apply?
Typical coating thickness ranges from 0.0003 to 0.0016 inches (8 to 40 microns), depending on application needs and part geometry.
Are your coatings compliant with military or aerospace standards?
Yes, we are MIL-SPEC compliant (MIL-PRF-46010 and others), serving aerospace, defense, and precision manufacturing clients.
