CorroLogic® VpCI® Filler, Patent Pending

Select a Product:


CorroLogic VpCI Filler is a custom designed 2-part product developed to fill the inside of closed environments such as pipeline casings and the inside of tubular tower structures, etc. in order to control corrosion for long time periods. The product contains a unique blend of Cortec Vapor phase Corrosion Inhibitor (VpCI) technology while providing resistance to bacterial corrosion. The filler also prevents the infiltration of air and water inside the filled structures.

CorroLogic VpCI Filler consists of a liquid VpCI concentrate and a powder gelling agent. The liquid VpCI component (Part A) can be diluted on-site to the appropriate concentration. The powder gelling agent (Part B) is added just prior to application and causes an increase in viscosity and ultimately gel formation over a pre-determined time period.


CorroLogic VpCI Filler is applied by adding the liquid VpCI concentrate to water in a mixing tank, thoroughly blending, then adding a controlled quantity of the powder gelling agent into the liquid stream as it is discharged from the mixing tank. The CorroLogic VpCI Filler is then pumped into the structure until it is filled to the desired level. After application, the CorroLogic VpCI Filler will setup and gel over a predetermined period of time. Contact a Cortec representative for the recommended mix ratio.


Part A is available in 5 gallon (19 liter) pails, 55 gallon (208 liter) drums, and bulk. Store in a heated warehouse to avoid freezing.

Part B is available in 50 pound (23 kg) and 100 pound (45kg) moisture barrier, fiber-lined drums. Store in a sealed container in a dry warehouse and avoid direct exposure to sunlight with temperatures not exceeding 150°F (65°C).
