VpCI®-422 G is a modification of VpCI®-422, which is recom- mended for galvanized steel.

It will not adversely affect most paints, plastics, wood, textiles, ceramics, or rubber when used as recommended. Removing corro-sion from metal is easy; just apply VpCI®-422 and rinse with water.
VpCI®-422 is completely organic and does not require special dis-posal for typical use. It is especially helpful for outdoor and marine applications where chemical waste disposal can be a problem. In rare situations, waste treatment may be required if large quantities of pollutants are accumulated during cleaning.

Unlike conventional rust removers, which can be extremely dan-gerous to use, handle, and store; VpCI®-422 is non-flam- mable and biodegradable. It can be used in labor-intensive areas such as continuous assembly and packaging lines mini- mizing effects on production efficiency.


FEATURES

•Prevents flash rusting
•Completely organic and readily biodegradable
•Non-polluting and environmentally acceptable (Check with local authorities for specific disposal guidelines)
•Loosens rust-frozen parts
•No adverse effects on most paints, plastics, wood, textiles, ce-ramics, and rubbers
•Non-flammable formulation and mild odor, ideal for in-plant use
•NSF (A3) Registered. Acceptable for use as an acid cleaner in and around food processing areas for indirect food contact
•Passes ASTM F-519-05 “Mechanical Hydrogen Embrittlement Evaluation of Plating/Coating Processes and Service Environ- ments”
•UFI: XRWX-11P3-YU1J-WXYR

TYPICAL APPLICATIONS
•In-process rust removal for parts and metal stock
•Interior and exterior surfaces of tanks and vessels
•Outdoor machinery and equipment
•Trucks, cars, and other vehicles
•Automotive, marine, and equipment
•Fences, railings, and walls
•Tools, locks, and rust-frozen parts

APPLICATION

VpCI®-422 can be applied using spray equipment including air and airless spray as well as by brush or dip.

For spray, brush, or roll-on application; remove loose rust or tarnish. Then apply VpCI®-422 concentrate to surface, let chemical stand for 10 to 15 minutes, and rinse with an alkaline solution (Cortec® VpCI®-41x Series). Typically, little or no rubbing is required. Reapply if necessary.

Let VpCI®-422 stand for longer time for medium and heavy rust. Soak part(s) in a tank as long as required to remove corrosion. Remove part(s) from tank and rinse with an alkaline solution (Cortec® VpCI®-41x Series). Increasing temperature up to 150
°F (65 °C), and/or agitation will speed the cleaning process.
