In industrial environments where corrosion and chemical attack are routine hazards, surface protection can be the difference between reliable uptime and costly downtime. Many coatings promise durability, but when chemical resistance is the priority, Halar (ECTFE) quietly outperforms the rest.
At Marcote, we often speak to manufacturers and engineers who’ve tried standard solutions like PTFE or FEP and found them lacking in aggressive chemical environments. That’s where Halar steps in.
What Makes Halar Coatings Different?
Halar is a type of fluoropolymer, similar in some ways to PTFE, but with its own unique properties. It doesn’t just hold up against heat and abrasion, it offers outstanding resistance to a wide range of chemicals, including acids, bases, solvents, and oxidising agents.
This makes it a reliable choice for coating components in sectors where chemical exposure is unavoidable: think chemical processing, pharmaceutical manufacturing, water treatment, or even semiconductor cleanrooms.
When other coatings start to degrade, Halar maintains its integrity, as well as keeping your equipment protected.
But it’s not just about what Halar coatings resist. Its smooth, low-permeability surface also helps prevent product contamination and makes clean-down easier, especially important in high-purity processes.
More Than Just Heat and Wear
You might already be familiar with coatings like PTFE or PFA, which in the right setting, do a great job. But Halar offers a different kind of advantage. While it operates at slightly lower maximum temperatures (200°C), its chemical shielding, mechanical strength, and electrical insulation properties make it invaluable in applications where heat isn’t the main concern.
For example, in pharmaceutical wash-down zones or acid-processing vessels, Halar provides a more robust long-term barrier. It’s also an excellent choice for areas where abrasion and impact resistance matter just as much as corrosion protection.
Where Halar Shines
The industries that rely on Halar coatings usually share one thing in common: failure isn’t an option. Whether it’s a mixing tank, pipework, valve, or pump component, these parts can’t afford to degrade, and production can’t afford to stop.
We’ve applied Halar coatings on components used in:
- Acid handling systems in chemical plants
- Solvent-heavy processes in pharmaceutical facilities
- Chlorinated environments in water treatment
- High-purity equipment in cleanrooms and lab settings
In aerospace, Halar is also used to coat jigs and fixtures that handle sensitive components, such as jet engine parts, during chemical treatments. The coating is tough enough to endure repeated chemical exposure, but soft enough to prevent damage to the component itself.
For example, a metal clamp coated in Halar won’t scratch the engine part it’s holding. In these environments, Halar plays a key role in stopping metal-to-metal contact.
In each case, Halar is chosen for its reliability under pressure, and its ability to hold up in places where most coatings fall short.
The Marcote Approach
Applying Halar isn’t just a matter of spraying and curing. It requires a detailed understanding of how the part will perform under real-world conditions, that’s where we bring value.
At Marcote, we don’t just deliver a coating; we work with you to understand the application, the risks, and the performance requirements. Then we tailor the coating process to suit.
From surface preparation to final cure, our methods are designed to meet demanding tolerances and industry standards, especially where safety and compliance are key.
In environments where components handle hazardous substances, coating failure isn’t just costly, it can pose a serious health and safety risk. That’s why we take every precaution to ensure reliability.
Why Halar Is Ideal for the Chemical Industry
In chemical manufacturing, equipment is constantly exposed to corrosive agents, aggressive cleaning protocols, and demanding process conditions. Over time, these elements degrade components, compromise safety, and disrupt production. Halar offers a level of chemical resistance that’s not just impressive, it’s essential.
For operators, that means fewer failures and lower maintenance costs. For compliance teams, it ensures materials meet industry safety and performance standards. And for procurement teams looking to invest in longevity, it provides an excellent return through reduced replacement cycles and unplanned downtime.
Whether it’s lining valves in acid-processing systems or protecting pipework from solvent attack, Halar delivers reliable, long-term protection in the kind of environments where coating failure isn’t an option. Its smooth, cleanable surface also makes it easier to maintain hygiene, supporting strict quality controls often required in chemical production.
If you’re in the chemical sector and struggling with corrosion, erosion, or contamination, Halar might be the upgrade your process has been waiting for.
Need Better Protection?
If you’re experiencing failures from chemical exposure, or if your current coating isn’t holding up as expected, let’s talk. Halar might not be the most talked-about fluoropolymer, but for many of our clients, it’s become the most valuable.
