Army Tank Treatment With SR-17

Here is a successful reaction photo of SR-17. Although SR-17 is not a pretty product, it is an effective product that neutralizes contaminants while increasing paint adhesion. The rust color you see in the first photo is called metal staining. The rust is gone. This is not rust. These are two army tanks that were dustless blasted and treated with SR-17 to eliminate flash rusting and chloride contamination. The customer left the tanks to sit outside. This is not a problem. After a month, he pressure washed the tanks to remove bird droppings, then primed and painted them. Keep in mind that after the pressure washing, the flash rusting will not return.

This method is similar to what the DOT can do on the bridge-bearing areas. These areas can be prepared via dustless blasting or low-tech mechanical rust removal methods (wire wheel etc.,) and treated with SR-17, with the same 100% success rate.

Barge Treated With SR-17

SR-17 to the rescue! Atlantic Soda Blast of North Carolina blasted this barge and treated only half of the barge to hold the blast. Unfortunately, they did not have enough to complete the barge, so after a few days, you can see flash rusting has begun on the untreated area. No problem, we delivered another 5-gallon bucket to treat the rest of the barge. The barge will be ready to paint as soon as SR-17 is completely dry. SR-17 will hold the blast on this barge for months or until the painter is ready to paint. SR-17 works every time it is used.

From the Owners Desk

I came across this abstract paper written by Arun S. Wagh concerning the formation of "Phosphate Ceramics" to prevent corrosion. This abstract is written more for nuclear waste containment, but to help to explain our phosphate process, Arun uses iron phosphate production to explain the chemical reaction that results in a crystalline phosphate structure that immobilizes corrosion. (Section 3.1.1)This abstract was published by the American Society of Naval Engineers. The paper presents the case for using a chemical reaction to develop a corrosion-resistant coating call "Phosphate Ceramics". In this abstract, it discusses the process of phosphate development which was discovered in the early 1900's. This is a pretty good explanation as to what SR-17 does to ferric oxide.
