Introduction:

In this document, we review the findings of the UL modified ASTM D117 Corrosion Testing of 11 brands of Final Coat modules (the protected experiments) and 11 panels without modules (the unprotected experiments). Specifically, we compare the measurements that were made by UL staff, using calipers on the actual panels, to those we made using image processing software, called ImageJ.

Conclusions:

The efficacy of protection by the modules, as a group, was calculated and shown in Table 4 for the two methods used in protected and unprotected analysis (calipers and measurement in ImageJ software). The calculation was done as follows, taking for example the case of the rusted ratio determined by the calipers method:

  1. The average (mean) percent of the scribe rusted was calculated for all eleven unprotected panels from the calipers measurement method.
  2. The average (mean) percent of the scribe rusted was calculated for all eleven protected panels from the calipers measurement method.
  3. The ratio (average rusted percent of unprotected) / (average rusted percent of protected) was then calculated for the calipers method.

The same procedure was used for the ImageJ method. A ratio greater than one indicates more rusting on the unprotected panels than protected panels. Using ImageJ, the unprotected panels have 15.2 times more rust than the automotive sheet metal panels protected by the Final Coat modules. Using calipers, the unprotected panels have 6.86 times more rust than the automotive sheet metal panels protected by the Final Coat modules.

Test Lab Report: #ATL-9560-06-17 Dated: 10/24/2017

Standard Salt Spray Test:

Corrosion tests in which the Sodium Chloride electrolyte solution was replaced by a Sodium Carbonate electrolyte solution. Two chambers, each with four panels. One chamber will test four panels protected with modules and the other chamber will test four unprotected panels. Scribing was done using a Dremel rotary tool with an abrasive cut-off wheel. There were a total of eighteen scribes per panel. The electrolyte was 0.01M sodium carbonate. This was from Alfa Aesar, catalog number A17484 (“sodium carbonate decahydrate, 99+%). The modules on the protected panel had a 12 volt power supply connected to them. A couple of times per week a oscilloscope was used to check and make sure that the modules were all functioning correctly throughout the experiment.

Results:

Testing for panels connected to the Final Coat modules started on 07/26/2017 and ended on 09/06/2017 (1000 hours). Testing for panels not connected to modules started on 07/27/2017 and ended on 09/07/2017 (1000 hours). Staggered start and end dates were due to the time necessary to make all the scribes as stated in the quote. Samples attached to modules were monitored daily and checked with an oscilloscope twice weekly to ensure functionality throughout. No abnormalities were observed in the process of ensuring the functionality. Following testing, C.A.P. Inc. evaluated the scribes for percentage rusted. Their determination was that the effectiveness was up to 4x less rust on protected panels compared to the unprotected panels

Objective and Introduction:

The objective of this experiment was to test the effectiveness of the CM-3000 in protecting scribes on one foot wide by four feet long galvanized steel panels. Eighteen scribes were made through the paint on each panel, purposely introducing damage sites where the effectiveness of protection could be visually assessed. Four protected and four unprotected panels were used in this experiment, with the unprotected panels serving as a control set for this visual comparison. Two separate Q-Fog Spray Chambers were used, one for the unprotected panels and the other for the panels protected by the Final Coat modules.

A modified ASTM B-117 exposure was used, with 0.01M Na2CO3 (sodium carbonate) replacing the ASTM standard 5% w/v NaCl as the electrolyte. We have used 0.01M sodium carbonate extensively in our testing. According to the hypothesis of how the module operates, zinc passivation is required to see an effect, and sodium carbonate is effective in inducing passivation of zinc.

Conclusions:

This testing showed that up to 28 times less rust accumulated on a scribe on a protected panel than on an unprotected panel, while on average there was 1.6 times less rust on the protected panel scribes than the unprotected panel scribes. The hypothesis of how the module works is that surface currents generated by the module break down passivation of zinc, allowing zinc to resume its role as an anode that protects steel against continued corrosion. These results are consistent with this hypothesis.

Type of Test:

Salt Spray over the scribed area only. Test was done to show the efficiency of the Final Coat Electronic Corrosion Module over a surface in the absence of an electrolyte (moisture) film and it’s ability to reduce the rate of corrosion. Test Panel Size: 4 feet x 3 feet.

Test Results:

“The corrosion rate is reduced by 99.7% by the Module on the Test Panel compared with the Control Panel. Even if the difference in the corrosion potential is reduced to -0.100V, the ratio (CR) test/ (CR) control = 0.0204 and hence the corrosion ratio is reduced by 98%. To put these numbers in perspective, imagine that a system (automobile) fails by corrosion without the Module in a time of 1 year. If the Module is attached, the failure time would be 343 years if the potential is displaced by 150 mV in the negative direction, and 49 years if the potential was displaced by only 100mV. Such results are particularly significant when one considers that the average life of a vehicle is in the order of 10 years. Accordingly, these calculations demonstrate that the reduction in corrosion rate is substantial and that the Module is an effective corrosion control device”.

Note:

The corrosion potentials measured at the scribes on both panels were approximately the same until exposure times exceeded 60 hours. The potentials then diverged, with that for the test panel eventually becoming more negative than that for the control panel by about 150mV, indicating that an induction time exists for the Corrosion Module.
