PTFE Coating Liquid | Teflon Spray Coating Liquid
Product Intro
Our Teflon PTFE coating liquid is a high-performance fluoropolymer dispersion for industrial spray coating. It forms a uniform, stable PTFE film after curing, widely used for mold release, dry lubrication, anti-sticking, chemical resistance and insulation. Easy to spray with common spray guns, consistent coating thickness, ideal for metal, aluminum, steel, plastic and fabric substrates.
Pain Points
- Mold & roller surface sticking, difficult demolding, frequent shutdown for cleaning, low production efficiency
- Sliding parts, guides, bearings suffer high friction, heavy wear, short service life, need frequent grease lubrication and maintenance
- Parts exposed to acid, alkali, solvent, oil and chemical splash, easy corrosion and surface damage
- High-temperature working components deform, stick residue, hard to clean
- Ordinary coating peels, cracks, poor adhesion, unstable non-stick effect
- Many PTFE coating liquid on the market contain PFOA, fail food-grade and industrial compliance requirements
- Uneven spray, poor dispersion, easy sedimentation, high waste rate during coating
Solution
Our PTFE Teflon spray coating liquid solves all these troubles.
✅ Ultra-low friction PTFE coating film, dry lubrication without grease, reduce wear of moving parts
✅ Excellent non-stick & release performance, mold residue easy to wipe, cut cleaning downtime
✅ Outstanding chemical resistance, resist acid, alkali, solvent, oil and most corrosive media
✅ High temperature resistance, stable performance under continuous high heat working condition

FAQ
Q1: What is PTFE coating liquid / Teflon coating liquid?
A: PTFE coating liquid is a PTFE dispersion. After spraying and sintering, it forms a dense Teflon film on substrate surface, with non-stick, low friction and chemical resistance properties.
Q2: Can I spray this PTFE coating liquid with normal spray gun?
A: Yes. Use conventional air spray gun. Filter the liquid before use, stir evenly to avoid sediment for uniform Teflon coating.
Q3: Is this PTFE coating liquid PFOA free?
A: Standard grade is PFOA-free. Food contact grade is available upon request, meets food safety requirements.
Q4: What is the curing process for Teflon spray coating liquid?
A: Pre-dry at 100–120℃ to remove water, then sinter at 360–380℃ for 8–12 minutes. Cooling naturally to get final non-stick PTFE coating.
Q5: Can this PTFE coating liquid work on plastic?
A: Only for high-temperature resistant plastics which can bear sintering temperature. For low-temperature plastic, please select our low-temperature curing PTFE coating grade.
Q6: What thickness can the PTFE coating reach?
A: Recommended dry film 15–40μm. Multiple spraying can achieve thicker coating upon demand.
Q7: Do you provide custom PTFE coating liquid?
A: Yes. We support custom solid content, color, food grade formula, low friction enhanced grade and low temperature curing Teflon coating liquid.
