DeCORE BE - 85

DeCORE BE and DeCORE BE-85 were tested at 0.5% by weight in hard water and/or distilllled water on cold rolled steel panels, in closed glass jars at room temperature for six months.
The bottom half of the metal panels were submerged in the test solutions. The top half of the panels were exposed to the vapor phase. Panels on the left did not contain inhibitor.
Steel Panels: SAE 1010 Cold Rolled Steel (mild carbon)

Control (no inhibitor) - (1st jar)
Distilllled Water - (2nd – 4th jars)

Cast Iron Chip Testing
Figure 1 depicts results of a 24 hour test using grade 35 cast iron chips tested in solution on filter paper. Each solution contained 1% by weight of corrosion inhibitor in hard water (100 ppm as CaCO₃ and 71 ppm as CaCl₂) at room temperature.

A = Control, no corrosion inhibitor
B = DeCORE APCI-95
C = DeCORE IMT-100LF
D = DeTROPE CA-100
E = DeCORE BE-85

Submersion Testing
Figures 2 and 3 illustrate the results of metal panel submersion testing in the presence of DeFOREST Enterprises corrosion inhibitors.

A = Control, no corrosion inhibitor
B = DeCORE IMT-100LF @ 0.5%
C = DeTROPE CA-100 @ 1.00%
D = DeCORE BE-85 @ 1.00%
Figure 2: Panels are hot dipped Zn/Fe galvanized (unpolished), 90gms; tested for 1 year.
Figure 3: Panels are bare aluminum at 0.063 inch thickness; tested for 2 years.
The top halves of the panels were submerged into a solution containing from 0.5 -1% by weight of corrosion inhibitor in hard water (100 ppm as CaCO₃ and 71 ppm as CaCl₂) at room temperature. The other half of the panel was exposed to the vapor phase in closed glass containers.

Figure 4 depicts result on ground 1/2 hard, low carbon cold rolled steel panels at 0.063 inch thickness after 2 years in the test solution.
A = Control
B = DeCORE IMT-100LF at 0.25%

D = DeCORE IMT-100LF at 0.50%
E = DeTROPE CA-100 at 0.50%
F = DeCORE BE-85 at 0.50%
G = DeCORE IMT-100LF at 1.00%
H = DeTROPE CA-100 at 1.00%
I = DeCORE BE-85 at 1.00%
