Cortec Reveals Salt Corrosion Prevention Plan


As winter approaches, corrosion-prevention company Cortec Corporation has announced a dual approach plan for slowing down vehicle corrosion from deicing salts.

According to the release, vehicles that apply deicing salts or fluids are at the highest risk for corrosion. Its two-step method includes fighting corrosion at the source and regular cleanup after salt exposure.

Cortec M-605 Series additives can be mixed with the deicer chloride prior to application. Available in three forms, the additives are reportedly nitrite-, chromate- and phosphate-free:

  • M-605 is a powder that can be added to NaCl based deicer to protect ferrous metal;
  • M-605 L is a liquid that can be added to deicing fluids and is especially effective against ferrous metal corrosion from MgCl2 deicers; and
  • M-605 PS is a USDA Certified Biobased Product that comes as a powder and is most effective in CaCl2 based deicers for protection of both ferrous and aluminum alloys.

“Leaving a vehicle to sit unwashed after driving around on winter roads, caked with chloride-rich road spray that has splashed up on the sides and bottom of the truck or car, is one of the quickest routes to rusting out a vehicle,” the company said. “Simple washing goes a long way toward removing chlorides so they cannot continue rusting the metal body and underbody components.”

Cortec offers a biobased cleaner, FlashCorr VpCI, which contains a combination of sufactants, chelating agents and corrosion inhibitors to neutralize and remove salt deposits on metal. The rinsing agent also provides flash protection for ferrous metals and can reportedly extend a vehicle’s service life.

The company states that the cleaner is non-flammable, nitrite-free and effective at low doses.

In August, Cortec announced its development of a new oil-based temporary coating that is meant to provide extreme corrosion protection in aggressive environments.

Described as a wet-film corrosion inhibitor and lubricant, VpCI-369 is designed for applications on auto service parts and heavy equipment components prior to assembly.

Specifically, the company says that the coating would be best utilized on bare, unpainted metal equipment parts that suppliers will have to then ship. Additionally, the coating can also be used on service parts or spares that will be laid aside for five or 10 years before they might be needed again (e.g., marine engine crankshafts).

Cortec notes that the lubricant is thixotropic and can be mixed so that the product can change consistency to enhance sprayability for application with an airless sprayer. Once sprayed, the solution will reportedly thicken, as to not run off the metal surface.
