CleanWirx 207 provides the only health, safety, and environmentally conscious metal surface preparation solution to exceed the highest standards for corrosion elimination, even in the most challenging heavy-industrial environments. 

The CleanWirx 207 One Step application process decontaminates surfaces at the molecular level, eliminating visually undetectable levels of highly corrosive substances, providing a uniform receptive surface prior to coatings application, and greatly increasing coating adhesion with NO film formers.

Historically the focus has been on the adverse anions (chlorides, sulfates nitrates) with little attention addressing the high aggregation of FeS (iron sulfide) on a substrate of today’s metal assets. Cleanwirx 207 reacts and solubilizes FeS (iron sulfide) with an oxidation process and solubilizes the ionically bonded FeCl2 (iron chloride) aggregated on the metal substrate, in addition reacts and solubilizes FeCl2 (iron chloride), SO2−(sulfate) and NO−3 (nitrate) over the general surface area to be decontaminated. The CleanWirx 207 addresses the cations and insoluble sulfides and chemically breaks the ionic attraction between the anions and cations and as a result eliminates the cathode-anode reaction (corrosion reaction)

The 207 addresses this phenomenon on contact and as a result will form and amorphous oxide later (Lewis acid) creating a uniform receptive to the entire surface, this would be the passivation state or layer which would be measured in nanometers. This amorphous oxidation phase would be considered an adduct/ electron receptive; this explains the extraordinary adhesion values that are achieved with this technology. In the many numbers of adhesion test done the tendency is the break the coatings cohesively rather than adhesively. My opinion as well as others more educated than myself would conclude we are achieving a covalent bond and the coating to substrate interface.

With reference to:

• Aluminum: what we have found; when blasting/cleaning, sodium bicarbonate and 207 will reform aluminum hydroxide and aluminum oxide when de-painting or decontaminating aluminum. Water and sodium bicarbonate by itself is corrosive to aluminum.

• Stainless steel: we have found the 207 does a remarkable job with reforming the chromium oxide on stainless steel. We are currently using the 207 with Stepan (letter attached) to re-passivate their stainless-steel assets.

• Concrete: we are currently moving in the concrete surface preparation market, because of laws addressing airborne particulate the market could be very good for the wet abrasive technology in preparation for coatings in this industry.

In summary the CleanWirx 207 results are a contaminant free substrate, does not react in solution, it only reacts with the aggregated cations and anions on the metal surface and leaves no film to interfere with coating adhesion at the coating to substrate interface.

1. How to know or verify that non-soluble salts (iron sulfide) are being removed from the surface?

The steel will not turn black which is typically a sulfate that is generate from the FeS from atmospheric oxygen. Other ways maybe the ion specific Chlor*Rid CSN test to identify sulfate or potassium ferricyanide which will detect Fe ions.

1. What is site test can be done to check/verify non-soluble salts are being removed?

Ways to test maybe the ion specific Chlor*Rid CSN test to identify sulfate or potassium ferricyanide which will detect Fe ions.
