Opaque Pre-Mix

Built for the photograph

This is the fluid for a build that gets shot. Solid, saturated colour reads consistently under studio light in a way a translucent dyed fluid never does, because there is no depth-dependent colour shift, a 16 mm tube and a full reservoir show the same colour.

It is listed for experienced builders

PrimoChill flags this one for people who already know their way around a loop, and the reason is maintenance discipline rather than difficulty of use. An opaque fluid needs daily colour-separation checks early on, because you cannot see trouble developing through it the way you can in a clear loop.

Prep is not optional here

Every warning that applies to Vue applies here, this is the same suspension chemistry. Residual machining oil or flux will interfere with the pigment suspension, and the failure mode is visible separation rather than a subtle haze. Run a full prep. Rad Clean, SysPrep, PrimoPrep, before the first fill.

Opaque Pre-Mix’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 2 years from purchase. Top up only with more Opaque Pre-Mix, never water.
