- Product Background
Crodacor BE is a water-soluble corrosion inhibitor compatible in a wide range of formulations, particularly aqueous based formulations contained within tin plated steel aerosol cans.
Crodacor BE has also proven to be an extremely effective corrosion inhibitor for cast iron, steel and other ferrous metals. Crodacor BE is recommended as a replacement for products that may have environmental concerns, such as sodium nitrite.

Corrosion Inhibition Performance
Two corrosion studies were completed to show the performance of Crodacor BE in the presence of DI water with and without a 250ppm NaCl solution.
Methodology
In the first study, tin plated steel cans, lined and unlined, were used to examine corrosion in an aerosol can. The lined cans had a double epoxy phenolic lining, which provided further chemical and corrosion resistance properties.
To perform the first corrosion test, several cans were cut in half and filled with a test solution. The test solutions included:
- DI water
- DI water with 250ppm NaCl
- DI water with 0.5% Crodacor BE
- DI water with 250ppm NaCl with 0.5% Crodacor BE.
The cans were covered and allowed to sit for 36 days at ambient conditions. After the 36 day test period, the cans were examined for corrosion.
In the second study, cold rolled steel coupons were partially submerged in a test solution. The jar with the test solution and coupon was then covered and allowed to sit for 36 days at ambient conditions. The test solutions used were the same as the above. After the 36 day test period, the coupons were examined for corrosion.
Corrosion Study 1: Tin plated steel aerosol cans (lined and unlined), Crodacor BE vs. DI Water with and without NaCl solution
Figure 1 highlights the anti-corrosion performance of 0.5% Crodacor BE in DI water after 36 days of exposure in an unlined tin plated steel can. The performance of Crodacor BE with the addition of 250ppm of NaCl solution is highlighted in figure 2. In figures 1 and 2, virtually no corrosion is observed in the unlined steel cans containing Crodacor BE, while cans with untreated solutions showed substantial corrosion.

Figure 2: Unlined tin plated steel cans after 36 days of exposure to a 250 ppm NaCl solution (left) and a 250 ppm NaCl solution with 0.5% Crodacor BE (right)
Figure 3 highlights the anti-corrosion performance of 0.5% CRODACOR BE in DI water after 36 days of exposure in a lined tin plated steel can. The lined cans had a double epoxy phenolic lining to provide further chemical and corrosion resistance properties. The performance of CRODACOR BE with the addition of 250ppm of NaCl solution is highlighted in figure 4. As shown in figures 3 and 4, there is considerably less corrosion in the lined cans containing CRODACOR BE than in the cans containing untreated solutions. The corrosion is most evident at the seams.

Corrosion Study 2: Cold Rolled Steel, Crodacor BE vs. DI Water with and without NaCl Solution
In the second corrosion study cold rolled steel coupons were submerged in solutions of DI water and 250 ppm NaCl, both with and without 0.5% Crodacor BE. The coupons were submerged for 36 days. After the test period, the coupons were removed and examined for corrosion. As shown in Figure 5, the samples that contained Crodacor BE did not develop any corrosion while the unprotected samples developed significant corrosion.
