Water-based rust prevention saves money

Cortec  has developed a  water-based rust preventative (RP) that reduces applied cost by 40% compared to a bestselling oil-based product. It is said to offer excellent corrosion protection while reducing carbon footprint and cutting common labour or disposal costs associated with traditional RPs.


EcoCorr Water-Based Rust Preventative powered by Nano VpCI is a complete replacement for oil-based rust preventatives  used for temporary indoor protection of equipment and components. It is convenient to use and easy to clean. When applied to the metal surface by dipping, brushing, or spraying, EcoCorr forms a clear dry film that is suitable for robotic assembly of precision machined components. In most cases, the dry film of EcoCorr does not interfere with use and does not need to be removed, but this can be easily done when required. EcoCorrWater-Based RP is useful for temporary storage of countless metal parts:

  • Castings, tubular parts, finished parts, gears
  • Pumps and housings
  • Structural steel, sintered metals
  • Bars and roll stock
  • Precision machined components

Freshly exposed metal surfaces are especially vulnerable to flash rust and corrosion between manufacturing process steps. In order to avoid losses from corrosion, it is very important to apply a rust preventative to protect metal parts awaiting the next step of machining, assembly, or shipment. This is typically done with an oil- or solvent-based RP, which can be messy, hazardous to use, and inconvenient to remove.

EcoCorr Water-Based RP improves plant cleanliness and worker safety by eliminating greasy spills; flammable RPs; and hazardous elements such as nitrite, phosphate, and hazardous amines. Special ventilation is not required for application, and labor and disposal costs associated with hazardous oil-residue removal are eliminated. All this can be done at a significant savings of 40 percent lower total applied cost—not to mention time saved between process steps.

Though oil- and solvent-based RPs are commonly relied on for their rust preventive qualities, EcoCorr Water-Based RP offers outstanding performance in an environmentally friendly, easy to use alternative. Under ASTM D-1748 testing, during which coated metal panels are exposed to approximately 100% relative humidity in high temperatures of 120°F (49°C), EcoCorr Water-Based RP provided more than 800 hours of protection.
