Cortec receive patent for filler

This patent is the 63rd patent that has been awarded to Cortec Corporation since its founding almost 40 years ago.

The CorroLogic VpCI filler was designed at the request of a North American pipeline corrosion engineering group that was looking for a product to protect annular void spaces between pipelines and their casings.

In response, Cortec Corporation researched and developed a two part VpCl filler product, which turns into a gel product that fills and protects the space from corrosion in the long term when mixed and pumped into structural void space. The filler also provides resistance to bacterial corrosion and prevents the infiltration of air and water inside the filled structures.

CorroLogic VpCI filler offers several advantages for protecting pipeline casings and other tubular structures. Its benefits include: little or no surface preparation is required, viscosity and setup time are controllable and the filler migrates under disbonded coatings and protects inaccessible and recessed surfaces.

Moreover, VpCI protection self-replenishes if space is unexpectedly subjected to moisture or outside air infiltration. It is compatible with cathodic protection and continues working in its absence. The filler can be removed by washing product off metal surfaces.

CorroLogic VpCI is made of biodegradable materials and is non-toxic, nonflammable, as well as nitrite and phosphate free. It is a practical and effective solution for long term corrosion protection in challenging environments, such as pipeline casings.

The filler complies with NACE Standard SP0208-2008.
