Teflon Coating Advantages
- Non-Stick Superiority - Contact angle >110° prevents material adhesion
- Chemical Resistance - Withstands concentrated acids/alkalis (pH 0-14)
- Thermal Stability - Continuous service at -200°C to +260°C
- Friction Reduction - Coefficient comparable to polished ice
- Electrical Insulation - Dielectric strength >100kV/mm
- Substrate Versatility - Compatible with steel, aluminum, ceramics, and polymers
Notes
- Maximum service temperature limited to 260°C (500°F) for non-degradation
- Requires surface roughness >2.0μm Ra for optimal adhesion
- Not recommended for high-pressure abrasive environments
- Post-coating machining strictly prohibited
- Requires 24hr curing before full operational use
Teflon Coating Applications
