Conventional rust removers can be very dangerous to use, handle, and store. For this reason, Cortec spent decades developing environmentally-safe corrosion protection solutions. Utilizing the latest technology, Cortec scientists created USDA 92% Certified, biobased, water-based, non-toxic, biodegradable EcoAir Non-Toxic Rust Remover that provides multi-metal corrosion protection.

Packaged in a non-flammable air-powered spray can, it removes rust and stains without polluting. 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 water. 

EcoAir 422 is completely organic 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.

Innovation in a Spray Can

The Eco Air 422 A Bio Based Non Toxic Rust Remover Eco Air PouchCortec CorporationEcoAir 422 Rust Remover is packaged in EcoAir - an air-powered spray can which makes a major step forward in the spray can technology. The spray can is powered by compressed air that completely replaces expensive chemical propellants. This technology is innovative because a four-layer EcoPouch is inserted into a recyclable aluminum can then pressurized - only the EcoPouch is filled with the liquid. As the valve is depressed the surrounding pressure expels the bag’s internal fluids until the product is used up. EcoAir packaging is safe to use, ship, and store and has no environmental impact or chemical propellants.
