Aerospace Teflon (PTFE) Coating Services
At National Aerospace Processing, we provide NADCAP-accredited Teflon® (PTFE) coating services that enhance the performance and reliability of metal components used in aerospace and defense applications. Teflon coatings, also known as PTFE coatings, are widely used to reduce friction, prevent galling, and improve chemical resistance in demanding operating environments. NAP applies aerospace-grade PTFE coatings using controlled dry film and spray-applied processes that align with the quality expectations of modern aircraft and military systems.
Types of Teflon (PTFE) Coatings
Dry Film PTFE Lubricant Coatings
Dry film Teflon (PTFE) lubricant coatings are commonly used in aerospace applications where low friction, anti-galling performance, and consistent torque are required. These coatings are often referenced in programs aligned with dry film lubricant standards such as MIL-PRF-46010 or AS5272, depending on application and customer requirements.
Features & Benefits
- Low Friction Performance: Reduces drag, galling, and wear on moving components.
- Improved Component Life: Helps extend service intervals in aerospace assemblies.
- Dry Film Application: Eliminates the need for wet lubricants in critical areas.
Spray-Applied PTFE Polymer Coatings
Spray-applied Teflon (PTFE) polymer coatings are commonly used in aerospace applications that require uniform coverage, controlled film thickness, and chemical resistance. These paint-like coatings are often associated with aerospace dry film and fluoropolymer coating practices and are applied using documented spray and cure procedures.
Features & Benefits
- Uniform Coating Thickness: Supports consistent performance across complex part geometries.
- Chemical Resistance: Resists exposure to fuels, oils, hydraulic fluids, and solvents.
- Controlled Application: Applied using qualified spray methods consistent with aerospace coating practices.
PTFE Coatings for Wear & Chemical Resistance
Teflon (PTFE) coatings are widely used to improve wear resistance and protect aerospace components exposed to repetitive contact, friction, and aggressive chemical environments. In aerospace programs, these coatings are often referenced alongside fluoropolymer or dry film lubricant specifications to support durability and long-term performance.
Features & Benefits
- Reduced Surface Wear: Helps protect substrates in high-contact applications.
- Chemical Stability: Maintains performance when exposed to corrosive fluids.
- Consistent Protection: Supports reliable operation across repeated cycles.
PTFE Coatings for Military & Defense Applications
In military and defense applications, Teflon (PTFE) coatings are commonly specified for components requiring lubricity, durability, and environmental resistance. These coatings are often used in conjunction with other surface treatments such as passivation or CARC painting and may be referenced in programs aligned with military dry film lubricant specifications such as MIL-PRF-46010.
Features & Benefits
- Defense-Oriented Performance: Suitable for harsh operational environments.
- Reduced Maintenance: Helps minimize wear and service requirements.
- Process-Controlled Application: Applied under documented, quality-driven coating procedures.
General Aerospace Teflon Coating Process
The aerospace PTFE coating process at NAP begins with controlled surface preparation to ensure proper adhesion and coating performance. Components are cleaned and prepared according to documented procedures before PTFE coatings are applied using spray techniques designed for consistent film thickness. Cure cycles and handling are managed to maintain coating integrity and repeatability.
NAP performs PTFE coating services under its NADCAP-certified aerospace quality system (AC7004) and NADCAP Chemical Processing accreditation, including AC7108/1 for Painting Dry Film Coatings. Quality controls focus on adhesion, coating uniformity, and process documentation to support customer and program requirements.
