Description
EcoAir® VpCI®-422 is Cortec’s water-based, non-toxic VpCI-422 organic rust remover in a non-flammable compressed-air can. It lifts rust and tarnish from steel, iron, copper, brass and chrome while its VpCI inhibitors protect the metal underneath, and it does it without acid fumes, caustic burns or a hazardous-waste stream. Twelve 14 oz (397 g) cans per case.
The can is the spot-repair format of the VpCI-422 family: rust bloom on a machine way, a stained stainless panel, a rusted fastener or fitting, a tool left out overnight, a mark on equipment that is about to ship. The chemistry is the same 92 % biobased organic rust remover as the bulk product: not aggressive to the base metal, and harmless to skin, most paints, plastics and rubber. EcoAir cans are air-powered: the formulation sits in a four-layer bag inside a can pressurized with air, so no propellant contaminates the product, the can sprays in any direction including upside down, and it ships by air freight without the storage or fire-insurance restrictions on solvent aerosols. It is not recommended for aluminum. The Cortec Product Consultation Guide classes it as a cleaner rather than a rust preventative, so neutralize and protect parts that will be stored.
Typical applications
- Spot rust removal on machine tools, fixtures and gauges
- Fasteners, hinges, locks and rust-frozen hardware
- Marine, automotive and plant maintenance
- Rust marks on painted equipment where an acid would lift the paint
How to apply EcoAir VpCI-422
- Pre-clean. Brush off loose, flaky rust and wipe away grease so the remover reaches the metal.
- Shake and spray the can well and spray directly onto the rusted area from a few inches away, at any angle.
- Keep it wet. Allow the product to work for several minutes; light rust releases in about 15 minutes, heavier rust takes longer. Do not let it dry on the part; re-spray or cover with plastic film on long dwell times and scrub with a brush to speed removal.
- Rinse. Wipe or rinse with water to remove dissolved rust and residual product.
- Neutralize and protect. Fresh steel flash rusts quickly. Spray with EcoSpray VpCI-416 or EcoAir VpCI-414 and let it dry, or apply a VpCI rust preventative such as EcoAir VpCI-377 for indoor storage.
- Storage. Store cans at room temperature. The contents are water-based, so do not let them freeze.
Where it fits in the Cortec line
EcoAir VpCI-422 is the aerosol arm of the VpCI-422 concentrate; move to the 5-gallon pail or 55-gallon drum for dip-tank derusting of parts by the basket. Its siblings are EcoClean 423 gel in a 16 oz bottle for vertical surfaces and the bulk VpCI-423 and VpCI-426 for aluminum and heavy scale. Neutralize with EcoSpray VpCI-416 or EcoAir VpCI-414. Production derusting and neutralizing run in the immersion and spray stages of Build-All and Magido aqueous parts washers. See the full rust prevention range for what comes after.
Field notes
A Racine, Wisconsin gear manufacturer used to blast or send out spare parts that had rusted in storage, delaying shipments by days. Now rusty parts are submerged in VpCI-422 for up to 20 minutes, rinsed, dipped immediately in VpCI-415, air-dried and shipped the same day; stock was later moved into VpCI-126 bags with BioPads so it no longer needs de-rusting. (Cortec Case History #489)
A Virginia gantry-crane gearbox rusty inside was restored without disassembly: filled with VpCI-422, soaked 20 minutes and rotated 5 minutes, three times; drained and filled with 1:1 VpCI-414 and water, rotated 30 minutes and drained; a borescope confirmed the rust was gone; then filled with oil plus M-531 and run 5 minutes at low speed. Two years of preservation. (Cortec Case History #828)
An axial-compressor spare blade carrier in Kazakhstan rusted in an unprotected wooden crate outdoors. It was de-rusted with EcoAir VpCI-423, cleaned and neutralized with EcoAir VpCI-414, given a final clean with ElectriCorr VpCI-239 and wrapped in VpCI-126 HP UV with EcoPouches inside, ready for two years of outdoor crate storage.
