HinderRUST Targets Ethanol Corrosion in Fuel Systems

Fluoramics says its HinderRUST corrosion inhibitor is designed to protect fuel infrastructure from ethanol-blended fuel vapors and moisture that can damage metal equipment. The company is pitching the product as a way to extend equipment life, cut maintenance costs and reduce leak risks in fuel storage and dispensing systems.

Why it matters: - Ethanol-blended fuels are creating more corrosion risk inside fuel system infrastructure. - The damage can affect pumps, tank sumps, tubing and fittings, raising repair costs and leak risks. - Fuel system operators face added pressure to protect equipment and limit contamination concerns.

What happened: - Fluoramics is promoting HinderRUST as a corrosion inhibitor for fuel system equipment exposed to ethanol vapors and moisture. - The Lewiston, Minnesota-based company says the product is designed to help protect metal surfaces from rust and oxidation. - Fluoramics pointed to July 21, 2026 as the release date for the announcement.

The details: - Industry studies show ethanol vapors can be highly corrosive in pump rooms, underground storage tank sumps and other confined spaces. - Ethanol is hygroscopic, so it absorbs moisture from the atmosphere. - Water accumulation in fuel storage systems can lead to phase separation and conditions that support microbes. - Those microbes can produce acetic acid, which creates corrosive vapors that attack metal components. - Corrosion can damage steel and cast-iron pump casings, copper tubing and fittings, and other equipment. - The result can be reduced reliability, more maintenance, higher replacement costs and possible fuel leaks. - Fluoramics says HinderRUST forms a protective barrier on internal components to help block moisture from contacting metal surfaces. - The company says the product is intended to extend equipment life, lower maintenance expenses and improve operational reliability across fuel storage and dispensing systems. - Fluoramics also says HinderRUST can help protect tanks, pumps and other fuel system components from ethanol-blended gasoline. - The company advises a broader corrosion-prevention approach that includes fuel conditioners and stabilizers, ethanol-compatible materials, routine inspections and properly sealed storage systems. - Fluoramics says the product helps safeguard critical fuel system components in demanding environments.

Between the lines: - The announcement frames ethanol corrosion as both a maintenance issue and an environmental risk. - The pitch suggests fuel operators may need a mix of chemical protection and infrastructure upgrades rather than a single fix. - The focus on confined spaces like sumps and pump rooms points to the hardest-to-protect parts of the system.

What's next: - Fuel system operators weighing corrosion controls may look at inhibitors, materials upgrades and inspection routines together. - Fluoramics directs readers to more information about HinderRUST and its corrosion protection solutions. - The company also lists social channels for additional product updates and outreach.

The bottom line: - HinderRUST is being positioned as a practical tool for operators trying to reduce ethanol-related corrosion, extend equipment life and avoid costly fuel system failures.
