ETFE Coating (Tefzel)

Key Features & Benefits

• Outstanding Chemical Resistance
  Resistant to a wide range of acids, alkalis, solvents, oxidizers, and chlorinated media.

• High Mechanical Strength & Abrasion Resistance
  Tougher than PTFE/FEP in many applications; resists wear, impact, and handling damage.

• Wide Temperature Capability
  Continuous service typically up to 150–170 °C, with excellent low-temperature toughness.

• Low Permeability
  Provides a dense barrier that minimizes gas and chemical permeation, extending equipment life.

• Smooth, Non-Stick Surface
  Reduces fouling, scaling, and product build-up; easy to clean and maintain.

• Strong Adhesion & Seamless Finish
  Fusion-bonded application delivers uniform thickness and reliable long-term adhesion.

• UV & Weather Resistance
  Suitable for outdoor installations, coastal and industrial atmospheres.

• Long Service Life, Low Maintenance
  Reduces recoating frequency and lifecycle costs.

Applications

• Chemical & Petrochemical Plants
  Pipes, valves, tanks, scrubbers, and ducts handling aggressive chemicals and fumes.

• Chlor-Alkali & Oxidizing Services
  Systems exposed to chlorine compounds and oxidizers require low permeation.

• Water & Wastewater Treatment
  Equipment exposed to disinfectants, corrosive dosing chemicals, and harsh effluents.

• Power Plants
  Flue-gas ducts, scrubbers, and cooling-water components.

• Oil & Gas
  Corrosion protection for specialty components and process equipment.

• Pharmaceutical & Specialty Chemicals
  Clean, non-contaminating surfaces with strong durability.

• Outdoor / Coastal Installations
  Excellent resistance to UV, humidity, and salt spray.
