VpCI®-422 effectively removes rust and tarnish from steel, iron, copper, and brass. VpCI®-422 removes corrosion from metal without creating waste disposal difficulties and is more operator friendly than traditional rust removers. VpCI®-422 G is a modification of VpCI®-422, which is recommended 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.
Description
VpCI®-422 effectively removes rust and tarnish from steel, iron, copper, and brass. VpCI®-422 removes corrosion from metal without creating waste disposal difficulties and is more
operator friendly than traditional rust removers.
VpCI®-422 G is a modification of VpCI®-422, which is recommended 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-flammable and biodegradable. It can be used in labor-intensive
areas such as continuous assembly and packaging lines minimizing effects on production efficiency.
FEATURES
• Removes rust and corrosion from ferrous and non-ferrous metals.
• 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 Environments”
• 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.
