Five UV gel lines, all of them fillable from 200 pcs per shade
In short
Senyuan makes five UV gel lines — base coat, colour, cat eye, builder and top coat — with roughly 10,000 standard shades on file. Every line is available from 200 pcs per shade, or 5 kg in bulk. All current formulas are HEMA-free and TPO-free, and viscosity is set to your application rather than to a single factory default.

Base coat
The adhesion layer. Formulated to the base coat you already use, or to the adhesion result you need — 4B by ASTM D3359 is our standard on natural nail and tips.
Available acid-free for sensitive markets, and HEMA-free as standard. Tell us your prep routine, because adhesion is a system: a 4B in our lab is only reproducible if your prep and cure match ours.
Colour
Roughly 10,000 standard shades on file, plus matching to your reference. Pantone, RAL, a physical sample or a photo — in that order of accuracy, because screen calibration and lighting shift colour more than most people expect.
Pigment load and opacity are set per shade, not averaged across the range. A dense white and a sheer nude behave differently under the same lamp, and a range that ignores that reads as cheap on the shelf.
Cat eye
Magnetic pigment, with the magnetic response tuned to the strength of the magnet you supply. Weak magnets need a more responsive pigment, and the difference shows in how sharply the line sits after curing.
We test with your magnet, not ours. Send one with the brief and we return samples with two or three pigment loadings so you can pick the effect you are actually selling.
Builder
Structure and apex for extensions and overlays. Viscosity is the whole conversation here: too thin and it runs before you can place it, too thick and it will not self-level.
We set viscosity to your application — brush, pot or syringe — and to your working temperature, which matters if your market is cold in winter and the gel behaves differently in transit.
Top coat
Non-yellowing, tested under UV ageing. Available in gloss and matte, with or without a dispersion layer, depending on whether your customers finish with alcohol or with a tack-free surface.
Shades and bulk
- Standard shade card: roughly 10,000 references, so a range can usually start from an existing formula rather than from zero.
- Custom shades: matched to your reference, three rounds of adjustment included.
- Bulk: from 5 kg per shade, in kg drums, if you fill and label in your own country.
- Packaging: you supply bottles, jars and closures, or we source them from our regular suppliers.
What we do not do
- We do not sell our own brand into your market, so there is no channel conflict with your range.
- We do not quote a unit price before we know the line and the shade. The range is USD 1.00–3.50 per bottle, and within that range the number depends on pigment cost and fill.
- We do not run a shade below 200 pcs and call it a sample. Samples are quoted separately, at cost.
Questions about a specific line
- What is your minimum order quantity?
- Can I order in bulk instead of bottles?
- Can you match a specific shade reference?
- Can you supply the packaging?
- What is the adhesion grade?
