P.T.F.E / Fluoropolymer Coatings – TEFCOT™

Engineered by BLINEX FILTER - COAT PVT LTD

Overview

BLINEX FILTER - COAT PVT LTD is a trusted Indian manufacturer and exporter with 50 years of engineering excellence (1975–2025) in advanced surface treatment technologies. The company specializes in high-performance PTFE fluoropolymer coatings, engineered to deliver superior non-stick performance, corrosion resistance, low friction, and chemical inertness for demanding industrial applications.

Backed by decades of process expertise and stringent quality control, TEFCOT™ PTFE coatings are designed to extend component life, improve operational efficiency, and significantly reduce maintenance costs in harsh service environments.

1. TEFCOT™ PTFE (Polytetrafluoroethylene) Coatings

PTFE is a pure fluoropolymer distinguished by its strong carbon–fluorine molecular bonds, resulting in exceptional thermal stability, chemical resistance, and ultra-low friction. TEFCOT™ PTFE coatings, developed by BLINEX FILTER - COAT PVT LTD, are applied using controlled industrial processes to ensure uniform coating thickness, excellent adhesion, and consistent performance.

Key Technical Characteristics:

  • Extremely low surface energy (true non-stick surface)
  • Chemically inert to almost all acids, alkalis, solvents, and industrial fluids
  • Hydrophobic and non-wetting behaviour
  • Excellent dielectric and electrical insulation properties
  • Resistant to fouling, scaling, and material build-up

2. Typical Performance Parameters

  • Operating temperature range: –200°C to +260°C
  • Coefficient of friction: ~0.04 – 0.10
  • Chemical resistance: Near universal
  • Moisture absorption: Negligible
  • Electrical resistivity: Very high

These properties make TEFCOT™ PTFE coatings among the most reliable solutions for continuous operation under extreme chemical and thermal conditions.

3. Key Benefits of TEFCOT™ PTFE Coatings

Corrosion Resistance: Forms a chemically inert, impermeable barrier that protects metal substrates from moisture, salt, chemicals, and corrosive environments.

Low Friction & Anti-Seize: Reduces torque requirements, prevents galling and seizing, and ensures smooth assembly and disassembly of threaded components.

Thermal Stability: Maintains coating integrity and performance under prolonged exposure to high operating temperatures.

Chemical Inertness: Unaffected by most industrial acids, alkalis, solvents, and aggressive process chemicals.

Non-Stick & Anti-Fouling: Prevents adhesion of powders, liquids, and residues, simplifying cleaning and maintenance.

4. Applications of TEFCOT™ PTFE Coatings

  • Industrial fasteners (nuts, bolts, studs)
  • Valves, seals, gaskets, and fittings
  • Textile machinery components
  • Chemical and process industry equipment
  • Food, bakery, and pharmaceutical machinery
  • Electrical and insulation components
