VpCI®-426 is a water-based heavy duty concentrate designed to remove corrosion, scale, and naturally occurring oxides from iron, carbon and stainless steel, copper, aluminum, magnesium, and their alloys
Description
VpCI®-426 not only removes corrosion and scale, but also brightens aluminum and copper.
FEATURES
• Rust remover for ferrous metals
• Preparation of aluminum surfaces before anodizing, painting, and electroplating
• Oxide removal of brass, bronze, copper, zinc, magnesium, and magnesium alloys
• Brightener for aluminum and copper
• Scale build-up remover from bathroom tubs, showers, and pipes
• Household corrosion removal needs
• NSN 6850-01-477-4155
ADVANTAGES
• Very effective on a variety of metals to dissolve rust, scale, and oxide deposits
• Reduced costs of surface preparation
• Increased performance over equivalent products
• Used in areas that can not be sandblasted or cleaned with power tools
• User friendly, and nitrite-free
• Available in the powder form (VpCI®-426 powder)
APPLICATION VpCI®-426 LIQUID (EXAMPLES)
Steel*:
Use 1 part of VpCI®-426 to 4 parts water.
Copper:
Use concentrate or 1:1 dilution with water.
Aluminum:
Heavy cleaning
Apply concentrate at room temperature or 1 part VpCI®-426 to 1
part water at elevated temperature (120°F/49°C).
Normal cleaning
Use 1 part VpCI®-426 to 1 part water.
Magnesium and alloys:
Use 1 part VpCI®-426 to 4 parts water at room temperature (cleans in approximately 1-2 minutes).
APPLICATION VpCI®-426 POWDER
Use 7% (by weight) in water.
*Once corrosion has been removed, it is advised to use Cortec® VpCI®-414 (1:5 and 1:10 dilutions) to rinse away any residue and prevent the metal surface from flash rusting.
