PRODUCT DESCRIPTION
VpCI-378 is a water-based concentrate designed as a complete replacement for oil-based corrosion preventives. VpCI-378 forms a brown emulsion in water and is applied to metal surfaces by spraying or dipping. The wide dilution range with water allows flexibility to customize the length of protection required vs. applied cost. The protective coating is also translucent and in ambient conditions becomes dry-totouch 30 minutes from application. VpCI-378 is designed to be removed with Cortec® VpCI-414 or other conventional alkaline cleaners. VpCI-378 is designed to protect ferrous and non-ferrous metals in sheltered areas, indoors or in packaging, with no direct exposure to rain or outdoor elements. In many operations, removal is not necessary since coatings or paints can be applied directly over treated surfaces at dilutions over 1:15.

FEATURES
• Forms clear and dry film, which renders attractive
appearance to protected parts
• Heat stable
• Displaces water from metal surfaces
• Easy to remove if necessary
• Eliminates cleaning and housekeeping problems associated
with oils
• Superior protection and complete replacement for rustinhibiting oils
• Emulsifiable, thus environmentally acceptable and safe to
apply
• Unique vapor phase action protects uncoated and difficultto-reach areas
• Economical – can be diluted up to 1 part VpCI-378 to 20
parts water
• User friendly
• Lubricating properties
