High-Performance PTFE Coatings for Demanding Applications
Teflon (Polytetrafluoroethylene, PTFE) coatings deliver a unique combination of low friction, chemical inertness, temperature resistance, and non-stick performance, making them ideal for parts operating in harsh or highly controlled environments.
MIL applies PTFE coatings to strict specification-driven requirements, ensuring consistent film build, strong adhesion, and stable performance across mission-critical components.
Teflon Coating Highlights
- Extremely low coefficient of friction (non-stick surface)
- Excellent chemical resistance
- High temperature stability
- Dielectric insulation properties
- Resistance to moisture, UV, and corrosive media
- Suitable for complex geometries and tight tolerances
- Applied to MIL-spec, AMS, and aerospace OEM requirements
How the Teflon (PTFE) Coating Process Works
Step 1 — Surface Preparation
A properly prepared substrate is essential for strong PTFE adhesion. MIL performs:
- Cleaning and degreasing
- Abrasive blasting (as required)
- Masking for tight-tolerance surfaces
- Surface conditioning for optimal bonding
Step 2 — Teflon Coating Application
PTFE coatings are sprayed as a thin, uniform film using controlled application methods to maintain required coverage and functional performance.
Benefits include:
- Improved wear resistance
- Reduced friction
- Corrosion protection
- Non-stick release properties
Step 3 — Thermal Curing
PTFE coatings require elevated cure temperatures to achieve full film properties. MIL ensures proper:
- Temperature profile
- Cure timing
- Film integrity and uniformity
Step 4 — Inspection & Verification
Quality validation includes:
- Film thickness measurement
- Appearance and adhesion checks
- Verification against coating spec
- Documentation for full traceability

Frequently Asked Questions About Teflon (PTFE) Coatings
They are used to provide low friction, non-stick surfaces, chemical resistance, temperature resistance, and electrical insulation on metal components.
PTFE coatings are typically applied in thin, controlled films, often between 0.5–2.0 mils, depending on the specification.
PTFE works well on:
- Aluminum
- Stainless steel
- Carbon steel
- Titanium
- Nickel alloys
Yes—PTFE coatings are widely used in actuators, linkage systems, wear components, and fasteners requiring long-term reliability under extreme environments.
Yes. Many parts use PTFE alongside:
- Chem film
- Solid film lubricants
- Metallic ceramic coatings
- MIL coordinates full multi-process workflows.
Industrial PTFE is engineered differently. MIL applies spec-driven, engineered PTFE systems designed for high-stress, high-heat, and mission-critical environments—not consumer cookware applications.
