Cortec EcoAir 422 Rust Remover

Conventional rust removers unfortunately can be very dangerous to use, handle, and store. For this reason Cortec® has spent decades developing environmentally responsible corrosion protection solutions.

Utilizing renewable technology, Cortec® scientists created EcoAir® 422 Rust Remover, which contains 92% USDA certified biobased content. The product is also biodegradable.

Packaged in an air-powered spray can, it removes rust and stains without polluting and is non-flammable. EcoAir® 422 will remove corrosion from metal without creating waste disposal difficulties and is far more operator friendly than traditional rust removers. It will not adversely affect paints, plastics, wood, textiles, ceramics, or rubber.

Removal of corrosion from metal is very easy: just apply the product and rinse with an alkaline solution such as EcoAir® 414. EcoAir® 422 has a high biobased content and does not require special disposal for typical use.* It is especially helpful for outdoor and marine applications where chemical waste disposal can be a problem. Rust Remover can be used in labor-intensive areas such as continuous assembly and packaging lines, minimizing effects on production efficiency.

VpCI®-422 G is also available as a modification of VpCI®-422 and is recommended for galvanized steel. E

coAir® 422 Rust Remover is packaged in EcoAir® air-powered spray cans, which represent a major step forward in spray can technology. The EcoAir® spray can is powered by compressed air that completely replaces traditional chemical propellants. This technology is innovative because a four-layer EcoPouch® is inserted into a recyclable aluminum can before the can is pressurized. Finally, the EcoPouch® is filled with the liquid product. As the valve is depressed, the surrounding pressure expels the bag’s internal fluids until the product is used up. EcoAir® packaging is safer to use, ship, and store than traditional aerosols with chemical propellants.
