VpCI-372 is a water-base corrosion inhibiting strippable coating. It provides protection in two ways: atmospheric corrosion and as a physical barrier to protect against nicks, abrasion, scratches, etc. VpCI-372 is used as a dry film, temporary coating for parts and equipment. The coating is stripped or peeled away prior to equipment use, and will not leave a residue.

Suggested Uses:

• Protection of clean metal surfaces for storage/shipping
• Protection of painted surfaces from physical abuse during storage/shipping
• Protection of clean surfaces during other finishing operations as a masking function
• Paint booths
• Tooling
• Keypads

Features:

• Water-based, VOC compliant
• Prevents corrosion/oxidation of metals
• Multimetal protection
• Does not cause contamination of surface upon removal
• Does not require special equipment for removal
• Can be disposed of as solid waste
• Fast drying
• Requires no solvents or paint/ink removers to remove coating
• High solids
• Available in various colors

Limitations:

• VpCI-372 can be applied to some plastics; however, each plastic needs to be checked for film removal with time.
• Dry thoroughly before peeling film. Minimum film build is 2 mils DFT (50 microns) for indoor applications and 8 mils DFT (200 microns) for outdoor applications.
• Do not expose cured film to extreme cold temperatures (lower than 10°F / -12°C).

Typical Application

VpCI-372 is supplied as a water-based, milky white liquid. It is applied by spray, brush, roll, or dip. It provides a clear film which allows for inspection of the surface. If desired, it may be tinted for easy identification of protected surfaces. The film can be peeled from the surface when it is thoroughly dried leaving a clean, ready-to-use substrate.
