Test of Rust Free usage on steel prior to painting

When it is applied to steel, it forms an emulsion of milky consistency that is cured to form a waxy solid over the course of a few hours.

The next photographs illustrate panels that were powder coated following Rust Free. The first set of images shows panels that haven’t been cleaned; these panels are severely blistered. When the panels are washed with a hose fitted with a normal nozzle, the waxy layer is removed to a large extent. When the coating was removed, the paint was applied and looked normal, but where Rust Free remains, the paint started to crack after the curing.

The PDS for Rust Free recommends that the coating is removed by the pressure washer the following cure. A high-pressure nozzle was attached to the hose to ensure that the coat was completely cleaned. The higher pressure of rinsing enabled the removal of the coating. The surface of the steel revealed some texture/color differences compared to the uncoated steel.

A brand new pole made of new metal was placed at our dock, directly towards the ocean. All structures were cleaned using Rust Free , except for the pipes that hold the poles.

It was exposed to extreme weather, which included a hurricane, over many months. The area that was not treated was covered with a PVC pipe and a cap that stopped rainwater from getting into. This PVC pipe was taken off after a couple of months. As you can see, the lower part is extremely and rusted. Rust Free also protected the adjacent region.

The entire area covered by the plastic poles is covered with Rust particles waiting to fall off the metal. It’s Fe3o4 which is a layer of protection that is similar to corten/weathering.
This is due to the treatment by the Rust Free.

SGS Australia ran untreated metal compared to treatment with Rust Free in the presence of 33 percent sulfuric acid.
This test is relevant to both the waste and mining industries, which employ sulfuric acid or similar. It is pertinent to mention that these industries employ a more dilute acid that is more of a 5-10 percent solution.
Tests were conducted on three samples that were not treated and three treated samples:
The first two samples in both (S1 and T1) were placed over the solution, and nothing occurred with respect to the metallics.
The second samples were taken (S2 and T2) and submerged at a quarter-way point in the solution. The portion of S2 metal submerged was completely gone by the acid’s effects.
Then, they obtained the third sample (S3 and T3) and submerged them completely in the solution for seven days.
The S3 metal completely vanished due to the acid’s effect, while T3 metal completely disappeared. T3 metal lost over half of its mass.
Another test was performed on a metal that was fully submerged (another S3) into the solution, it was found that the metal disintegrated after 18 hours.
It’s hard to figure out how to estimate the resistance of different metals that incorporate our Rust Free by using various acids.
However, we can confirm that the results demonstrate that a metal treated using Rust Free produces a superior result than one not treated.
