Showcase colour with a concentrate’s economics. Add DI water and you have a gallon of opaque fluid.
Swatches are visual approximations of the listed range, always confirm against a physical sample for a colour-matched build.
This is the opaque range in concentrate form, the same solid, saturated colour and the same suspension chemistry as Vue and the Opaque Pre-Mix, finished with your own DI water. For a large loop that needs more than 32 oz, it is substantially cheaper per litre than buying pre-mix.
An opaque concentrate is less forgiving of a casual mix than a transparent one. Get the ratio wrong and you do not get a slightly paler fluid, you get a suspension that is either under-loaded and streaky or over-loaded and prone to dropping out. One gallon of DI, the whole bottle, mixed thoroughly.
Two True colours mixed together are not a new colour, they are two pigment packages competing for suspension. The listing is explicit about this and so are we: one colour per fill.
Fill slowly and bleed for 24 hours with the pump running and the system off. Check every fitting twice, a paper towel under each joint tells you more than a pressure gauge.
True — Non-Transparent’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 concentrate is good for 2 years from purchase. Top up only with more True — Non-Transparent, never water.
