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.
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.
Package: VpCI®-422 and VpCI®-422 G are available in 5 gallon (19 L), 55 gallon (208 L) drums, totes, and bulk. To ensure best product performance, store in original packaging, indoors, and out of direct sunlight at 40-100 °F (4-38 °C).
