Redline (and PurpleIce) test results.. over a year later
 

Jan 19 , 2002 i decided to test the corrosion abilities of Redline and PurpleIce

but to save you the long read.. (however if you DO have questions.. read the above thread first.. as almost all have been asked there)

I created Full strength (4oz to 1 gallon water) half strength (2oz to 1 gallon) mixtures of each. I also threw in distilled water.. and a few days after i started the test i added in a standard tap water sample...

each sample is a cup of the sollution, with a piece of copper pipe and piece of aluminum pipe. then sealed with plasticwrap and a rubber band. yes not the perfect test atmosphere.. but it did the job.


Results after a few days: redline and waterwetter created an anodized-like coating on the aluminum.. protecting it from corrosion. Tap water will soon start showing corrosion.

2 months : The distilled started showing signs of corrosion. Purple Ice had a settling of a white powdery substance (probably wouldnt happen in a system with movement).. but no corrosion.


OVER 1 YEAR LATER:

Redline shows no corrosion in either mixtures

PurpleIce shows no corrosion in either mixtures.. but the color has gone, and the white powder has settled.

Distilled water has lots of corrosion and oxidation.

Tap water is just nasty.



now you will notice that the water level has dropped about 50%.. but i think overall we see that Redline can holdup for a good year without needing mainenence.. and yes not many use aluminum/copper.. but this was a stress test on the additive.. but factors such as using silicone tubing that absorbs the additives.. etc.. may vary your miledge, and also remember the BLACK ALUMINUM is the protective coating created by the additive... ITS GOOD.




the final pic.. over a year later:

3 days after experiment:

1 hour after experiment

I remember that thread, very interesting to see how things panned out

Since it's been recently been pointed out by Bill, do you notice a thin slimy deposit on the Water Wetter mixtures?

nope.. no slime in my tests.

however i did (along with other peopl) experience a white coating in my tubes that acumulated over time when using water wetter (redline).

this seems to be some sort of contaminant. perhaps liquid teflon being broken down by the redline? I never did figure that one out... but the stuff was greasy feeling.

About that white material:

I did something a little different a while ago. I ran the system with distilled water intending to add WW later once it was leak tested. Well school started and I put it off. After about 2.5 months I finally added it.

The instant the WW hit my res it turned BRIGHT white. In a second or two my entire loop turned to milk :eek:

Gradually it settled out and coated my tubes over the next month or so. I applied acid to it, but was unable to remove it from my tube.

My guess is its a reaction between something dissolved in the water and WW.

Was this a brand new res? Where from?

What's the res made out of?

Maybe the slime is from evaporated Water Wetter, redline. It takes a pretty long time at a few degrees above ambient for water to evaporate.

I made it out of transparent PVC.

Where did u get the perspex? what size is it and what did u use for the end caps m8?
