ECTFE / Halar® & PVDF Coatings

ECTFE, ETFE, and PVDF fluoropolymer coatings are engineered for vessels, tanks, reactors, and heat exchangers operating in highly corrosive and aggressive chemical environments. These coatings provide a dense, non-porous protective barrier that safeguards metal substrates against severe chemical attack, corrosion, and permeation.

Applied at a high coating thickness of 800 to 1000 microns, these fluoropolymer systems deliver long-term corrosion protection and reliability, making them ideal for critical process equipment in chemical, pharmaceutical, and specialty industries.

Why ECTFE / ETFE / PVDF Coatings Are Used

Process equipment such as vessels and heat exchangers are continuously exposed to strong acids, alkalis, solvents, chlorides, and high-purity chemicals. Conventional coatings often fail under such conditions. ECTFE, ETFE, and PVDF coatings are selected for their exceptional chemical resistance, thermal stability, and mechanical durability.

Key Advantages

Outstanding Corrosion Resistance - Excellent resistance to acids, alkalis, solvents, halogens, and aggressive chemicals.
High Build Coating Thickness - Applied at 800–1000 microns, ensuring superior barrier protection and long service life.
Chemical Inertness & Low Permeation - Minimises chemical absorption and protects base metal integrity.
High Temperature Resistance - Suitable for demanding process and heat transfer applications.
Smooth, Non-Stick Surface - Reduces fouling, scaling, and product build-up inside vessels and exchangers.
Excellent Adhesion & Mechanical Strength - Withstands thermal cycling and operational stress.
Easy to Clean & Maintain - Supports high-purity and contamination-sensitive processes.

Applications

ECTFE, ETFE, and PVDF coatings are widely used on:

Chemical Process Vessels & Reactors
Heat Exchangers & Condensers
Storage Tanks & Columns
Agitators, Internals & Nozzles
Pharmaceutical & API Equipment
Specialty Chemical & Petrochemical Plants
Corrosion-Critical Process Equipment
