PRESS RELEASE: S-8 Food Can Corrosion Inhibitor Awarded USDA Certified Biobased Product Label!

Posted on by

Cortec® Corporation is pleased to announce that its S-8 corrosion inhibitor additive for food-can processing has been awarded the USDA Certified Biobased Product label! S-8 is now able to display a unique USDA label that highlights its percentage of biobased content and signifies its qualification to meet mandatory federal purchasing requirements under the USDA BioPreferred® Program.*

“We applaud Cortec® Corporation for earning the USDA Certified Biobased Product label,” said Vernell Thompson, USDA BioPreferred® Program. “Products from Cortec® Corporation are contributing to an everexpanding marketplace that adds value to renewable agriculture commodities, creates jobs in rural communities, and decreases our reliance on petroleum.” Cortec® is proud of this “green” chemistry achievement and addition to its growing line of USDA certified biobased products, which represent a long-standing commitment to environmental responsibility.

S-8 contains 71% USDA certified biobased content and is formulated with FDA compliant ingredients.† It is designed for corrosion protection of sealed
food cans during washing and sterilization. While most of a can’s life may be spent sitting on a shelf in a dry environment, newly packed and sealed cans
pass through hot steam for sterilization, sometimes followed by a cold-water bath, before ever reaching the warehouse, store, or pantry shelf. Exposure of the metal can to steam, water, and air at this stage of processing is a perfect recipe for corrosion, which could lead to serious repercussions for the producer, seller, and consumer if not properly addressed. S-8 can be added at a very low dose to the sterilization and cooling water to safeguard against the risk of flash corrosion from rinsing and sterilization.

Three phases of inhibitor action—in the water, in the air, and at the air-water interface—give S-8 unique protective abilities for the steam sterilization environment, inhibiting corrosion even when the cans are not fully submerged in S-8 treated water. The additive leaves behind a persistent thin protective layer that will not cause sticky deposits on the surface of the can. Benchtop laboratory tests show outstanding film persistency and stability in a wide temperature range. This “green” filming corrosion inhibitor contains salts of fatty amino acids and amino alcohols as the active ingredients and does not hydrolyze during application.

A large food can producer in Croatia started using S- 8 in 2012 in conjunction with S-14 for corrosion protection and scale control in process water used to wash and sterilize cans. The water treatment additives solved the scale and corrosion problems, and, as of five years later, it was reported that these
two products were still being used with satisfaction.

Cortec® is proud to contribute to the marketplace with a “green” chemistry product that is both useful and sustainable. First, the product meets an important need to protect food cans from flash rust at the end of the canning process. Second, the product uses FDA compliant materials to make it suitable for use on packed and sealed food cans. Third, the product relies on renewable, biobased raw materials to reduce the consumption of non-renewable resources. Furthermore, S-8 can be used by US federal agencies and their contractors who need to meet minimum biobased content levels when purchasing corrosion inhibitors.

PRESS RELEASE: Cortec® Awarded Patent for Innovative Fire Sprinkler Corrosion Mitigation Technology!

Posted on by

Cortec® is pleased to announce its newest US patent for corrosion mitigation inside dry sprinkler systems!
While sprinklers are designed to fight fire, they themselves are at elevated risk for corrosion during their service life. Sprinkler corrosion problems are serious enough that National Fire Protection Agency (NFPA) standards for sprinklers call for corrosion risk evaluation at installation and periodic corrosion monitoring thereafter.* Cortec® has developed its patented sprinkler protection process as a simple, cost-effective solution to this problem.

A Practical Solution for Hard-to-Reach Void Spaces
Cortec’s patent covers a comprehensive system of protection that relies on Vapor phase Corrosion Inhibitors (VpCI® or VCI). This technology does not require the direct application of the corrosion inhibitors to every metal surface that needs protection. Rather, the vapor pressure of the corrosion inhibitors, delivered in powder or fluid form, will allow them to vaporize and disperse throughout the piping voids to access even difficult to reach spaces. Vapor phase Corrosion Inhibitors are attracted to metal surfaces, where they adsorb in a protective layer that interferes with the normal corrosion reaction fostered by the presence of oxygen and an electrolyte (e.g., residual water). These Vapor phase Corrosion Inhibitors are able to work in both the liquid phase and the vapor phase, allowing them to protect both wet and dry surfaces within the pipe.

Customizable Application Options
At least two methods of Vapor phase Corrosion Inhibitor application exist. One option is to use VpCI® fogging fluid to deliver the corrosion inhibitors immediately through the dry pipes. The other employs more gradual vapor dispersion by placing dry Vapor phase Corrosion Inhibitors in a housing connected to a pressurized air system that constantly circulates the protective vapors through the piping. This comprehensive system also includes efficacy monitoring methods such as corrosion coupons or sensors.

Benefits of Cortec® Patented Fire Sprinkler Protection
The primary benefit of Cortec’s fire sprinkler protection system is the mitigation of corrosion inside dry sprinkler pipes, helping the sprinklers last longer with less likelihood of failure. This significantly reduces the risk of leakage and clogging due to corrosion, in turn reducing the need for expensive and time-consuming repairs or pipe replacements. At the same time, the system is easy to install, requires little to no maintenance, and is economical and effective. These benefits are a huge advantage over traditional nitrogen purge, which can be expensive and difficult to maintain, and for which failure is not uncommon.

Another Example of Corrosion Technology Leadership
Cortec® strives to be a leader in developing practical solutions for corrosion needs in all industries. This fire sprinkler corrosion mitigation system is an excellent example of how Cortec® has provided a cost-effective, comprehensive, groundbreaking solution that departs from the status quo. It is an important technology to consider as an effective alternative to traditional protection processes that can easily fail or be difficult to maintain.
