Home made UV dyes

[gmat]

Allso has any one noriced fading of the dyes with in there system who is running nickle plated blocks ...

Interesting. I'm running your candy red + biocide in a mostly nickel loop... i'll get back to you if i notice something. How long would it take to start fading ?

well we have seen it fade our selfs with UV green when the biocide is to strong and it happens over hours not days. Now i have been shown some pics of a mix with no biocide and a mixture of Purple , candy red and UV pink fading in a nickle plated system with in hours (2 day period). So I need to see if its happening with any one else.

this is a pic of the system



So i need to know if this is happning with any one else so that we can eleimate this problem.

Like i say though i have seen this my self with strong biocide (wich we fixed) and it some thing i can repaet over and over again.... but ive not seen it happen in any of my systems that are running these colours on normal biocide.

No colour fading here. (I'll post some pictures later and run an other temperature test to see if everything is still OK)


What you would like to know is what did he use as a coolant before he was using your dyes. There's a good chance that there was still some coolant in the loop after flushing his watercooling and that there was something in the coolant that doesn't like your dyes.

I don't see sediment in the reservoir or in the tubes so I'm guessing that the dye sticks to his watercooling blocks and/or rad.


Is there also a picture before the fading of the dye so we could see the difference?

Nope no sedement or any thing apearing and no blocks getting dyed or clogged.

I used the loop once before with deionized water and swiftech's mix. But i took it all apart. BUT i rinsed it all with hot hot "spring" water. Then blew the water out.

So i am thinking if there is a reaction to the small amount of spring water left in the loop

Wich has got me thinking becuase like you and me we both seen it happen to green with the Biocide being way to strong but i never seen it since i fixed that problem. So my only though is along the line a reaction to some thing else that was put in the system to cause this to happen.

I have had 20 bottles stroed away now comming upto 12 months with the dyes in them and none have faded and allso the systems in our home again none have faded ect ect. So im stupped as to wather it his block , some kind of reaction to prev biocide or some thing else. this is another one of the pics sent to me



It looks like evry thing has gone accept the purple and that looks like 1 drop of pruple only that is left.

Been running tests this morning with UV pink and Candy red and a boat load of "raw" biocide and there has been a slight change but nothing on that scale so its totaly got me stumped. I even done a few phone calls and this has got quite a few ppl scratching there heads as it just shouldnt happen with any of the dyes i produce unless like you say its something in the equasion that i dont know about. Now if say a producer of a biocide is using either a bleech based product or some thing else i forgot its name then that will happen ... Makes me wonder what some of these produces are water cooling liquids use in there products.

It's a pitty that I don't have the testing samples. I could've done a test with the HydrX and the dye mixture to see what happens.


I think that the best way to prepare your loop for the dyes is to flush it and run a few days with pure water and than flush it again. Making the dye mixture with the Biocide in a glass of water to test it for a few days before putting it in your loop could be a good idea.

Ill sort you out some stuff once im sorted with the new bottles for the pre mix as im sort of spending alot of time trying to get the bottles and stickers and logos atm lol. Its a very fine balance between cost and sales atm and with out one the other ain happning hehe.
