Compatibility of Cortec Additives with Fuchs Fineblanking Oil
Compatibility of Cortec Additives with Fuchs Fineblanking Oil
Background: A.T. Wall currently utilizes Fuchs Fineblanking Oil 43 Light with Fuchs Chlorlok-BLK added for corrosion protection. They are exploring other options for corrosion inhibition.
Purpose: Determine which Cortec additive will provide the best corrosion protection when mixed with Fuchs Fineblanking Oil 43 Light.
Materials: M-238
M-529
Fuchs Fineblanking Oil 43 Light
Fuchs Chlorlok-BLK
Method: ASTM D-1748, Humidity Cabinet
Standardized Compatibility Test
Procedure: The following samples were created:
Table 1
Compatibility
The following procedure was followed:
- The samples were mixed and observed
- Compatibility is rated as a homogenous mixture with no gelling, precipitates, adverse reactions, or other deleterious affects
- The sample is listed as ok if considered compatible.
- The samples are cycled, 8 hours at 0° C and 16 hours 50° C, and observed at the different intervals. This is considered one cycle and the test is three cycles in duration.
ASTM-D-1748
- Carbon Steel panels were coated mixtures listed in table 1 and allowed to dry for 24 hours
- The panels were placed in the humidity cabinet for 296 hours, periodically inspected, removed, pictures were taken and a report was written.
Results: The following results were found:
ASTM-D-1748 Humidity Cabinet
Panel |
Time to Failure (hours) |
A |
72 |
B |
DNF |
C |
240 |
D |
DNF |
DNF = did not fail during the test, 296 hours
Conclusion: M-238 and M-529 are fully compatible with Fuchs Fineblanking Oil 43 Light, and they both outperform Fuchs Chlorlok-BLK in corrosion protection when added to the base oil.
