CorroLogic® VpCI® filler patented is an innovative environmentally friendly solution designed to fill and protect annular void spaces between pipelines and their casings from corrosion for long periods of time. The two-part system combines a liquid Vapor phase Corrosion Inhibitor concentrate with a powder gelling agent. After the liquid VpCI® concentrate is mixed with water, the gelling agent is added to the liquid stream as the VpCI® solution is discharged from the tank and pumped into the structure.
The product then turns into a gel at a predetermined set time inside the void space being protected. Little or no surface preparation is required, and the product can be removed by washing it off the metal surface. Vapor-phase corrosion inhibiting action protects inaccessible and recessed surfaces, or migrates to provide corrosion protection under disbonded coatings. The filler resists bacterial corrosion and prevents infiltration of air and water inside the filled structures.
