Vue

A dyed suspension

Conventional coloured coolants are dyes in solution: the colour dissolves and the fluid stays transparent. Vue is dyed too, but it also holds fine solid particles evenly through the fluid, and those are what make it opaque. White is the exception, particles with no dye. The colour only reads as solid while the particles stay suspended, and everything on this page is about keeping them there.

Why it asks more of your prep

Machining oil, brazing flux and plasticiser all interfere with suspension. In a clear loop you might see a faint film and shrug. In an opaque loop the same contamination shows as separation, colour pooling low in the reservoir, thinner fluid above it. Almost every "my Vue separated" is a loop that went together without a full prep.

UV behaviour

Three greens in the range are UV reactive. The rest are not, and no amount of UV lighting will make them glow, reactivity is a property of the specific formulation. Continuous UV exposure does degrade any dye package over time, so treat heavy UV lighting as a reason to inspect more often.

Vue’s life in the loop depends on pump hours and how restrictive the loop is, not the calendar, so we will not promise a number. Twelve months is the outside limit; a loop run hard every day can wear a fill out in weeks. Unopened, the bottle is good for 6 months from purchase. Top up only with more Vue, never water.
