The PTFE Coating for Hardware & Automotive is a powder-based fluoropolymer coating engineered to provide dry lubrication, wear resistance, and corrosion protection. It extends the lifespan of fasteners, pistons, gears, and other moving components in demanding mechanical systems.
Product Description
This PTFE-based powder coating is specifically engineered for hardware components, automotive parts, and precision metal mechanisms that require low friction, high wear resistance, and long-term corrosion protection.
The coating forms a uniform, dry-lubricating surface that reduces metal-to-metal contact and enhances part longevity under dynamic mechanical stress. Unlike traditional greases or oils, it provides clean lubrication without contamination, making it ideal for high-precision and maintenance-sensitive applications.
Key Features:
Excellent low-friction, self-lubricating surface
High wear resistance under dynamic load
Long-lasting corrosion and chemical protection
Provides clean dry lubrication (no grease required)
Uniform coating thickness with strong adhesion
Suitable for mass production of hardware & automotive parts
Typical Applications:
Fasteners, bolts, and screws
Pistons and cylinder components
Gear housings and sliding parts
Valve components and connectors
Automotive moving parts and assemblies

Q1: Why is PTFE coating better than traditional lubrication (oil/grease)?
A1: PTFE provides a clean, dry-lubricating surface that does not attract dust, dirt, or oil residue. It ensures longer-lasting wear resistance and reduces the need for frequent maintenance.
Q2: Can PTFE coatings be applied to all metals?
A2: Yes. PTFE coatings are compatible with steel, stainless steel, aluminum, and alloys, provided proper surface preparation is done before application.
Q3: What industries use PTFE automotive coatings?
A3: Widely used in automotive, aerospace, precision hardware, and industrial machinery, where friction reduction and corrosion protection are critical.
Q4: How thick is the PTFE coating layer?
A4: Typically 15–30 μm, but it can be adjusted based on specific application requirements.
Q5: Is the PTFE coating resistant to chemicals and salt spray?
A5: Yes. PTFE coatings are resistant to acids, solvents, oils, and salt spray corrosion, ensuring reliable protection in harsh environments.
