Hey there folks. For my current watercooling build, I'm wanting to use some sort of UV dye addative in the coolant. I've looked around at different stores and found that most yellow UV dyes tend to glow green instead of yellow. Where can I find a nice bright yellow UV dye? Any help would be greatly appreciated. THANKS! :)
 
Take a visit to Chernobyl, lick everything in sight. Then go home, and piss in your reservoir. Voila, glowing yellow.
 
I think all "yellow" UV dyes have sort of a greenish tint to them, or it could just be a product of the pictures having bad colors.

EDIT : LOL SocceRich

Yeaaaaa.....ok. I was looking for a reply a little more useful, and didn't require a plane ticket. :p
 
Dip a good old yellow high lighter in your res...give it a minute or two and your water will be glowing. really

Are you serious? I've heard about this trick before but I always think it would gum up or have a bad interaction with the pump or tubes.
 
Eh, you would have to use alot of highlighter ink... All the highlighters I've used for UV reactive dye didn't work as well as I thought it would, but if you can't find anything else then go ahead and give it a shot.

Actually, from what I've read you don't want to actually make contact with the highlighters wick and the water as small amounts of fibers from the wick will get in your cooling system and gum up waterblocks and pumps. I read that you simply pop the bottom endcap off the highlighter and squeeze a few drops into the water before filling your loop and test its UV reactivness to see if its bright enough. Need it brighter? Add a smidge more.

When I got off work this morning (ugh, 4 o'clock in the morning) I made a quick run over to Rite Aid and got a 2-pack of Avery brand "HI-LITER" flourescent markers. I got home, popped off the endcap of the highlighter and squeezed a little into an old clear plastic ziplock container with some tap water in it. I tell ya, this stuff disperses QUICK! Within 2 seconds everything turned a weird flourescent yellowish-greenish color. Almost the same color as Mt. Dew soda. Anyways, I turned on an old 24" UV light that I have hangin around and POW! This stuff lit up like it was radioactive! It was so bright the whole room had this funky yellowish-greenish glow. The glow is definatly more on the green side though. :(

I may just end out using these instead of an actual dye, but I would still be interested in hearing about good bright yellow UV dyes. :D
 
Hey, thats a good idea. I think most highlighters fluoresce. You could have blue, pink, and I think they also make green highlighters...
 
so it is safe and okay to do this then? if so, thats sweet, you could have any color you wanted :D
 
From what I understand, not all highlighters will work. Only the ones that are listed as "Flourescent". I tried a regular highlighter before this flourescent one and it didn't do a damned thing. :p Also, from what I've read the yellow flourescent highlighters are the only color that really glows well. The green, blue and pink ones seem to be quite dull.

Anyways, back to the topic at hand. Does anyone have any information leading to a good quality bright YELLOW uv dye? Once again, any information would be greatly appreciated. Thank you. :D
 
if you are concerned about fibers, just pour your water thru a coffee filter or similar. If you just dip it in, it isn't that much of a concern, it really takes very little for it to glow. Just dip the tip in...lol
 
I believe it is techline that makes dyes for leak testing of fluids. Thier radiator coolant dye is yellow with a littlr green tint to it and shows quite well.

Well I've ordered some yellow UV dye from cool-cases-usa.com and I'll let you guys know how it turns out. :)

*SNIP*

Ok, well when I checked the mail the yellow UV dye had arrived! I grabbed another ziplock container and put some tap water in it and added 3 drops of cool-cases-usa.com's yellow UV dye. This stuff doesn't disperse very quickly. Instead, it does this psychedelic yellow/green/brown swirling. Kinda reminds me of a storm cloud.

I mixed the dye with a toothpick to get the color to blend in properly. I then placed the yellow UV dye down next to the ziplock container containing the water/hi-liter mixture and there was quite a noticable difference even with the UV light off. The hi-liter mix definatly looked lime-green whilst the yellow UV dye looked like...well...pee. What else did you expect? After I chuckled for a sec, I reached over and turned on the 24" UV tube and POW, both colors glowed brilliantly. Here is a picture of the mixtures side-by-side. I altered the picture with photoshop to get the correct colors. For some reason my Casio QV-2300UX digital camera wanted to make the hi-liter mix look light blue. :mad:

Here is the Yellow UV dye mixture with a couple of red CCFL tubes and the UV tube on to show what the interior colors of my case shall be.

So, what have we learned? Well I've learned that cool-cases-usa.com has some kick-arse yellow UV dye that costs only $4.50. :D
 
Hey all...This is a pretty amazing thread. I really like the pics! Right now I want to see the brightest blue and also, onetime (at band camp) I saw this really cool UV white dye. That would also be cool to see.
