Violet sits between Blue and Orange. Blue's 8–15 µm can be too thick for tight-tolerance inspection. Violet's 4–8 µm layer gives you precision without rushing — the preferred choice for professional metrologists worldwide.
The 2–6 hour scan window lets you work methodically through complex parts without constantly re-spraying. Take your time on positioning, reference targets, and multiple passes.
Evaporates completely within 24 hours. Zero residue, zero cleanup. Delicate metrology components that can't be cleaned mechanically are completely safe.
Hold the can 15–20 cm from the surface. Apply an even coat with smooth back-and-forth strokes. One pass is sufficient — avoid wagging the can.
Begin scanning once the coating is stable and dry to the touch. Reference targets adhere cleanly to the coated surface. Re-spray areas as needed.
The coating sublimates completely — no cleaning required. Parts are reusable with zero residue. Higher temperatures accelerate sublimation.

Metrology work requires both accuracy and time. Violet's 4–8 µm layer is thin enough that dimensional offset is negligible for most inspection workflows, while its 2–6 hour window gives operators the time they need to capture every critical feature. It's why Violet has become the go-to choice among professional metrologists worldwide.

Blue: ~1–2hr scan, 8–15 µm. Violet: 2–6hr scan, 4–8 µm. Orange: 4–8hr scan, 2–6 µm. Violet is the precision middle ground — thinner than Blue, longer window than Blue.
Yes. Widely used with articulated arm CMMs, laser trackers, and handheld structured light scanners for precision inspection. The 4–8 µm layer works for most GD&T inspection workflows.
