Mayhem Pastel Coolant with PETG tubing?

shonik09 · 7 Jul 2016 at 16:29

Hi guys,

So I've been looking into coolants to use with PETG tubing, and am considering Mayhem Pastel coolants. However both jayz2cents and OC3D have had issues with the colour changing and gunk buildup.

I just wanted to check if anyone else has had similar issues, and how reliable the pastel coolants really are for use with PETG tubing?

Thanks!

Yep had same problem with mine. Nobody really seems to know why but it started sticking to the inside of my PETG. Im planning to give it another shot though as it looks great.

How long did it take for that to happen? Really don't want to have to redo everything after just one month...

If you were to use a clear coloured coolant however and treat the outside of the PETG with some frosting you might get a cool matt look which is both unique and not messing with your cooling

Its pretty easy to frost glass/acrylic, I'm thinking about it for my next build update so thought i'd share the idea... Would glow really well under lighting.

It's not the tubing it's just the pastel itself. Apparently it's to do with how complex and restrictive the loop is and what kind of flow you have. I will be using pastel fluid for my build never the less as it's epic and this problem is more obvious on the lighter colours. I plan to use blue so it should be okay.

Do you mean with frosted glass spray paint? I've seen that stuff for use on windows etc, but didn't know you could use on PETG tubing. I guess no reason why not though come to think of it?

It took around 4 months for it to start i think. It was like the pigment was dropping out of it.

This is the crud it left in my tubing. Took a lot of flushing to get clear again but Mayhems helped me out.

Its used in craft on acrylic quite a lot, a lot of internal facing bathroom glass is also acrylic and frosted in that way. If you want to get really serious about it you can probably get them sand blasted once finished if you wanted...

Worth a look around and maybe even a test for the £5 of spray.

I think Primochill do some frosted res tubes also by the way...
