When using coolant dye...

i think it depends on the color also as some pigments are worse than others in regard to response to certain frequency of light

the red end of the spectrum is particularly bad afaik will have to ask a mate who is some sort of proffesor in natual photonics or something similarly weird

but yer as far as i know its the reds are bad

and type of tubing ofc temperature and so on

so some systems will have more propbs than others ..

UV Pink (or some call UV red) will stain like mad UV clear blue will never stain.

Red, yellow, orange, blue, green, UV yellow green, UV green, UV blue take a while to stain depending on the amount you use.

If you would like colour but don't what staining don't add to much tint (dye) to the water. Heat has a large factor in staining as well and the hotter your Loop the more it will stain. Allso take into account the PH level as this all so helps staining. Keeping it around 6.5 to 8 you should be oky with slow staining (expect for UV pink this is just horrendous for staining and cannot be avoided).

Pigments do not stain and never will. Pigments use a binder (vehicle to carry the pigment along it merry way) dyes do not. Pigments are not dyes they are crushed plastic or crushed minerals (man made or other wise stated normally via MSDS Sheets), Pigments are insoluble in liquids and Dyes are soluble. For some stupid reason "some"makers of water cooling based dyes and fluids don't even know what they put in there dyes and incorrectly name them pigments (this is a big give away they do not make there own fluids and don't even know what's in them and this is were we differ).

e.g Aurora use pigments and dyes, Pastel uses nano pigments and dyes, x1 is dye based. Cameleon (unrealised to public) is slurry, pigment, nano pigment and dye based.

We've have been working on a pigment based fluid for quite some time with the first attempts marked down as complete failures.

ok maybe i used the wrong word in "pigment" then but basically the red end is worse than the blue end yes ?
i was going on what i rememebr from a mate i used to work with years ago
Prof. Peter Vukusic and one of his talks i attended

and the red end of the spectrum stuck with me for some reason as in it always seems that red cars fade more than blues etc
 
Yes you are correct red fades like mad and your correct about the spectrum of light ect ect. red is the worst for fading but not staining. UV Pink (in the scientific community its called UV Red, Bright red and a few other words i dare not say on here lol.) is a nightmare ...
