Products - VpCI®-423 Gel

Product Description

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.

When used as recommended, VpCI®-423 will not harm human skin or adversely affect most paints, plastics, wood, textiles, ceramics, or rubber. Removing 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% biodegradable, 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 chemical solution.

Unlike conventional rust removers which can be extremely 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 vertical 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.

How to Use

(typically, little or no rubbing is required).
Reapply if necessary. Medium and heavy rust will take somewhat longer.
