Applying RG-2400®


A solution for many hidden corrosion problems

Thanks for visiting the ReactiveGel website. If you have problems with Corrosion Under Insulation (CUI), in crevices, or otherwise hidden corrosion, you will find a solution here.

ReactiveGel is different from anything you’ve seen:

To understand this unique material, which is protected by multiple patents internationally, perhaps the first thing to know is that it is totally different. ReactiveGel is applied as a gel – and instead of curing or hardening, it remains in gel form. Within a short time, chemical elements in the gel react with elements in the steel surface. This reaction forms an ultra-thin glasslike mineral surface. This surface, along with pH adjusting chemistry in the gel, is what protects the steel underneath from corrosion. See a graphic explanation by clicking here (How It Works)

ReactiveGel works best on corrosion you can’t see:

Usage of ReactiveGelAnti Corrosion Coatings is spreading fast for Corrosion Under Insulation applications such as:

CUI Artic Pic

Insulated Transmission Pipelines

CUI on Tanks

Insulated Tanks

Insulated Valves and Fittings

Insulated Valves and Fittings

CUI Process Piping

Insulated Process Piping

Ammonia Systems

Ammonia Systems

Bundled Pipe

Bundled Pipe

Usage of ReactiveGel has many other applications such as:

Marine Cables

US Navy Wire Rope

Marine Anchor Links

US Navy Detachable Anchor Links

Tank chimes

Chime crevices at tank bottoms

ReactiveGel got its start by solving critical corrosion problems:

The U.S. Navy found its operations handicapped by watertight doors frozen by hidden corrosion, and by critical steel cables weakened by crevice corrosion. (Click for details)

Oil and gas producers north of the Arctic Circle became concerned about potential environmentally damaging spills caused by corrosion in Annular Well Casings and under insulation. (Click for details)

Food Manufacturers, who use refrigerated processing in their operations, worried about process shutdowns and leaks from corroded Ammonia Refrigeration lines. With these lines, leaks can be life threatening, environmentally damaging, and extremely costly. (Click for details)
