When it comes to industrial coatings, Halar® (ECTFE) stands out as one of the most reliable and high-performance options available. Known for its resistance to extreme temperatures, chemical exposure, and electrical conductivity, Halar coatings are trusted across industries such as electronics, chemical processing, mining, pharmaceuticals, and semiconductor manufacturing. At Precision Dip Coating, we apply Halar coatings using advanced techniques to deliver ultra-pure, smooth, and durable surfaces that meet strict regulatory and performance demands.

Halar is the brand name for ethylene chlorotrifluoroethylene (ECTFE), a semi-crystalline fluoropolymer similar to PTFE (Teflon). It’s recognized for its exceptional:

• Dielectric strength
• Temperature resistance
• Friction-reducing properties
• Chemical resistance
• Non-stick, non-porous surface

These features make Halar an ideal coating solution for high-risk, high-purity environments—especially in applications where other coatings may fail.

Halar’s versatility and durability make it a top choice in the following sectors:

• Electronics and semiconductors – For insulating sensitive components
• Pharmaceutical and medical equipment – Where sterility and chemical resistance are critical
• Chemical processing and storage – Piping, tanks, valves, and fittings exposed to aggressive chemicals
• Mining and heavy industry – Protective coatings for high-wear components
• Aerospace and defense – Where weight, thermal performance, and insulation are key factors
• Exhaust and ventilation systems – Especially in corrosive or high-heat environments

1. Temperature Resistance

Halar performs reliably across a wide temperature range, from -80°C to 150°C in non-load-bearing applications. It maintains flexibility and durability even in sub-zero environments, while its high limiting oxygen index (LOI) of 52% gives it excellent flame resistance—making it suitable for exhaust ductwork, cleanroom systems, and thermal shielding.

2. Friction Reduction and Smooth Surface Finish

Halar’s ultra-smooth, non-stick surface drastically reduces friction, which is critical in moving parts such as:

• Bearings
• Valves
• Actuators
• Seals and cams

Its non-porous structure prevents debris, dust, or microbial buildup, making it ideal for environments where hygiene and performance go hand in hand. Reduced friction also leads to longer equipment life and lower maintenance costs.

3. Electrical Insulation and Dielectric Protection

With a low dielectric constant and excellent electrical resistance, Halar provides outstanding insulation properties. It's especially effective for:

• Wire and cable jacketing
• Circuit board insulation
• Electrical enclosures and connectors

Special additives can also be introduced to modify conductivity or add anti-static properties, depending on the specific needs of your application.

4. Chemical and Corrosion Resistance

Halar offers long-term protection against acids, solvents, alkalis, and oxidizing agents. This makes it ideal for:

• Chemical storage tanks and liners
• Fume hoods and scrubbers
• Industrial piping systems
• Process components exposed to harsh fluids



It’s also highly resistant to UV, moisture, and environmental degradation, making it a reliable long-term solution.

Advancements in Halar application methods—including waterborne Halar coatings and the ability to coat certain plastic substrates—are expanding its role in sustainability and complex manufacturing environments. This innovation allows Halar to be used on lightweight components or in industries seeking eco-friendly coating alternatives.
