Custom OEM
Custom UV gel manufacturing, from your shade card to your label
In short
We formulate UV gel to your reference and your specification: colour, viscosity, adhesion, cure response, and whether the formula is HEMA-free. Three rounds of adjustment are included, led by an engineer with fifteen years in UV gel. The minimum is 200 pcs per shade, samples take 5–7 days, and production runs 15–20 days after you approve a sealed standard.
What you can specify
| Parameter | What we can do | What we need from you |
|---|---|---|
| Colour | Match Pantone, RAL, a physical sample or a photo; ~10,000 standard shades to start from | The reference, and the substrate you cure on |
| Viscosity | Adjusted to your application — brush-on, pot, or syringe | Target viscosity or a competitor sample to measure |
| Adhesion | 4B by ASTM D3359 on natural nail and tips | Your prep steps and base coat, since adhesion is a system |
| Cure response | 365–405 nm, peak 395–405 nm | Your lamp: wavelength and wattage |
| HEMA / TPO | Free of both, in current formulas | Your market's limit, if it is tighter than the EU baseline |
| Finish | Gloss, matte, cat eye, magnetic response strength | The effect you are selling |
| Packaging | Bottle, jar or kg drum; you supply or we source | Spec sheet, closure type, label dimensions |
| Label | Private label, your artwork, your shade names | Print-ready file, and the mandatory text for your market |
How matching works
Round 1 — direction. We send a first batch built from your reference. You compare it on the nail, not on paper, because colour reads differently once cured on a curved surface.
Round 2 — correction. You tell us what is off in physical terms: too thick, too yellow, shrinkage at the free edge, adhesion failing after four days. Vague feedback costs a round; specific feedback usually lands in one.
Round 3 — lock. We adjust and send the final sample. When you approve, we keep a sealed standard and every production batch is checked against it.
Three rounds are included. A fourth is possible and quoted separately.
What we need from you to start
- Shade references: Pantone or RAL codes, physical samples, or photos — in that order of accuracy.
- Packaging format: bottle, jar or bulk, plus who supplies it.
- Target market: country, because labelling and notification requirements differ.
- First order quantity per shade, and the total.
- Launch date, if you have a fixed one.
- Any formula constraint you already know: HEMA-free, TPO-free, acid-free, peel-off, or a limit from your own regulatory review.
Send these and the sample clock starts. Without them, we are guessing, and guessing costs a round.
What sits outside the standard scope
Being clear about this saves both sides a month.
- Colour tolerance. We match to the sealed standard. If you need a tighter tolerance than a normal production run holds, that has to be written into the standard before production, not argued afterwards.
- Formula ownership. Your shade card and your artwork stay yours. The base formulation stays ours; you get the documentation you need for your regulatory file, under NDA where required.
- Regulatory filing. CPNP notification is filed by your responsible person and paid by you. We supply the data and answer the assessor.
- Testing for a changed formula. A formula you change needs its own test report. A report on a previous formula does not carry over.
- Volume pricing. If your model is one shade at 20,000 pcs, a custom conversation is the wrong instrument — tell us and we will quote it as volume instead.
