VpCI®-423 Gel

VpCI-423 is a rust remover that is harmless to people while effectively removing rust and tarnish from steel, iron, copper, brass, chrome, and aluminum. VpCI-423 removes corrosion from metal without creating waste disposal difficulties. Available in a 5 gallon pail.

When used as recommended, VpCI-423 will not harm human skin or adversely affect most paints, plastics, wood, textiles, ceramics, or rubber. Remov-ing corrosion from metal is easy. Apply VpCI-423 and rinse with water then use Cortec® VpCI-414 or VpCI-419 for added protection.

VpCI-423 is completely organic and 100% bio-degradable, and does not have special disposal requirements for typical use. Waste treatment may be required if a sufficient quantity of pollutants (oil, solvents, dirt, grease) are introduced into the chemi-cal solution.

Unlike conventional rust removers which can be ex-tremely dangerous to use, handle, and store; VpCI- 423 is so mild that minimal protective covering is needed. In addition, the non-toxic, non-flammable formulation has no pungent acid fumes. Being nearly odorless and extremely mild makes VpCI-423 easy to use.

VpCI-423 is formulated to stay in place for special applications that require the chemical to cling to ver-tical surfaces or the underside of horizontal surfaces. VpCI-423 makes it easy to remove rust from tanks, vessels, outdoor machinery and equipment, walls, fences, railings, and vehicles.

VpCI-423 has been certified certified as a USDA certified biobased product and has been awarded USDA BioPreferred designation. (www.biopreferred.gov)
