Cortec VpCI-391 is a water-borne, temporary coating that is intended for medium to long-term indoor and outdoor protection. Once dried, VpCI-391 builds a non-tacky transparent film on the metal surface that provides excellent salt, humidity, and UV resistance.

  • Clear coating allows visual inspection of metal substrate
  • Provides excellent corrosion protection
  • Can be removed using an alkaline cleaner such as VpCI-414
  • Water-dilutable
  • Environmentally friendly and safe to apply
  • Cost-effective - protects at very low Dry Film Thickness (DFT)
  • Works in SO2 and HCL environments
  • Available in different colors (Contact us for more information.)


  • Carbon steel
  • Cast iron
  • Aluminum
  • Stainless steel
  • Galvanized steel
