SMIDA Nail Gel and Pigment Dispersion Mixer: From 100-Micron Clumps to Fine Colloids

What is a pigment dispersion mixer for nail gel?
It is a blade-free centrifugal machine that breaks pigment agglomerates down to micron-level fineness and removes air under vacuum for true, stable color.

Nail gel is built from photo-curable resin, reactive diluent, photoinitiator, and pigment or filler.
Cured color and performance depend on how well the pigments are dispersed — the industry's recognized process core.
As the nail market expands fast, dispersion quality separates premium brands from the rest.

Typical Problems in Color Paste Dispersion

•Pigment agglomeration.
Pigment powders are fine with large specific surface area, so they clump into particles of tens to hundreds of microns.
The result: gritty application and dull color.

•Uneven dispersion.
The same formula produces visibly different shades between batches.

•Bubbles ruin the look.
Air makes the gel whitish and cloudy, and the cured surface finishes uneven.

•Over-grinding damage.
Excessive milling destroys the color performance of shear-sensitive pigments.

A Proven Dispersion Workflow

1.Pre-mix wetting.
Mix pigment with the resin base at 500-1000 rpm for 1-2 minutes so the powder wets out evenly.

2.Centrifugal dispersion.
Run at 1500-2000 rpm for 2-4 minutes to break agglomerates as particles refine.

3.Vacuum degassing.
Degas down to 0.2 kPa for 2-3 minutes until the colloid turns clear and translucent.

4.Fineness check.
Confirm particle size with a grind gauge or particle analyzer — typically below 10 µm.

Why SMIDA for Color Paste

•Even, gentle shear.
Centrifugal shear is uniform with no local over-shear, so agglomerates break while pigment morphology and color performance stay intact.

•Sealed cups.
Sealed cups prevent solvent evaporation and moisture pickup for consistent batches.

•Dual-cup design.
Compare two formulas side by side in one cycle to accelerate R&D iteration.

•One platform, every scale.
From 150 g samples to 100 kg+ production with the same parameters, mixing volumes from 1 g to 100 kg+.
Factory direct: 17+ years, CE, ISO 9001, ISO 14001, ISO 45001, 2,000+ customers in 40+ countries.

Quick Answers

Can it handle shear-sensitive pigments?

Yes.
No blade touches the material — agglomerates break without damaging pigment shape.

How do I verify dispersion quality?

Use a grind gauge or particle size analyzer — typically below 10 µm.

Can I test two formulas at once?

Yes.
The dual-cup design runs two formulations in one cycle, ideal for comparing samples.

The color business is about stably reproducing the design — send a sample to the SMIDA lab to validate dispersion before you commit.
