Waiting on Mindchill for a special project we are working on (after about eleventy million e-mails... lol). I have a 20% mix in the loop right now with some of your deep blue and UV blue dyes. I have yet to use it in the cold side of the project as the order is still en-route through USPS.
I say beginning of February, I put the thing to work and can give you exact results.
The good news is I haven't seen a temp diffrence between pure DI water and a 20% mix. Flow rates are the same (better by 150ml/m when the water is warmed up actually), but that stuff is sticky... =P
Thanks for checking up! I'll be sure to let you know how things go!
