We are confident our product will work. Therefore, we guarantee no rust on your steel for 30 years!

“The worst sale we could ever make is one that doesn’t meet the customer’s needs.”

EonCoat’s CUI (corrosion under insulation) Coating works just like our EonCoat Corrosion Protection Coating by alloying the carbon steel after one application lays down both layers of protection. This chemically bonded phosphate ceramic coating is rated from -256°F to 842°F (-160°C to 450°C) and performs exceptionally well under insulation where moisture can easily creep in and create corrosion. While EonCoatCUI is applied at atmospheric conditions, it does an amazing job handling extreme temperatures of carbon steel assets under insulation.

Our CUI Coating is available in 9-gallon kits (4.5 gallons of Part A and 4.5 gallons of Part B) and 600mL Cartridges (300mL of Part A & 300mL of Part B)

We recommend this coating be applied at a minimum dry film thickness (DFT) of 20 mils / 500 microns or a wet film thickness (WFT) of 25 mils / 630 microns.

It can be applied directly to tightly-bonded surface rust and requires that no old paint or mill scale is present when applying our CUI Coating.

The coating is cured in 15 minutes.

EonCoat CUI Coating is water-based, inorganic, and has NO VOCs, NO HAPs, no toxins, and no odor.

You can easily dispose of unused EonCoat.

Our coatings require minimum personal protection equipment to apply (safety goggles and N95 mask).

EonCoat is less expensive to apply, safer for the people, and better for the environment without compromising coating longevity or performance.

CUI Buckets and Cartridges
Large or small, we coat them all!

How can you purchase EonCoat CUI Coating?

EonCoat CUI Coating is available for purchase in two forms. For smaller jobs, touchups, trials, and demonstrations, you can purchase prefilled 600 mL cartridges that work seamlessly with the dual-component cartridge spray gun. For larger jobs, you can purchase EonCoat CUI Coating as a kit of 9 gallons – that’s 4.5 gallons of Part A (acid) and 4.5 gallons of Part B (base).

From a test run to full-scale coating projects, we will help you succeed.

How Can EonCoat CUI Coating be Applied?

We designed the EonCoat CUI Coating to have the same straightforward application methods as our flagship product. Owners and managers with large, insulated assets typically opt for the high-pressure plural pump for large-scale jobs. However, the dual-component cartridge spray gun is a tremendous method to trial EonCoat CUI or touch up a larger job.

Offshore and onshore – let’s talk!

What industries benefit from using our CUI Coating?

A wide variety of industries utilize EonCoat’s CUI Coating for their corrosion prevention projects. With a broad temperature range of -256°F through 842°F (-160°C through 450°C), this coating can handle rapid temperature swings while preventing the hard-to-see corrosion that is common under insulation. That makes owners and managers of insulated pipelines, aboveground storage tanks, and other insulated assets some of our biggest fans.
