Technical Details & Test Data

Corrosion Testing Using Decore AFCI-45
  • Metal Panel Submersion Test

The bottom half of each metal panel was submerged in solution containing 0.25% - 1.0% DeCORE™ AFCI-45 by weight, in hard water (100 ppm as CaCO₃ and 71 ppm as CaCl₂ ) at room temperature. The top half of the panel was exposed to the vapor phase in closed glass containers. All results are after 12 weeks elapsed.

  • Steel Panels: SAE 1010 Cold rolled steel (mild carbon)

Decore AFCI-45 Hydrotrope Data
  • Decore AFCI-45 is an excellent hydrotrope for alkaline systems as depicted in the graph below.
  • Performance was determined and compared to several other DeForest hydrotropes and to SXS-40.
  • Each hydrotrope was solubilized in a caustic or alkaline electrolyte solution followed by addition of nonylphenol ethoxylate (NPE-9.5).
  • Each sample was heated to the temperature at which the NPE-9.5 clouds out of solution.
  • The higher the cloud point temperature, the more efficient the hydrotrope.

Test Formulation: 5% NPE-9, 3.7% Hydrotrope (by wt), 91.25% Electrolyte
