What are NAILINK press-on nails made from?
They use a PMMA acrylic structural base, HEMA-free pre-cured gel colour and finishing layers, and a removable jelly-tab attachment. These layers are stated separately because they do different jobs.

Quick answer
A finished press-on is a system: base material and geometry, colour and finish, width and curve, adhesive contact, daily movement and removal. NAILINK uses a PMMA acrylic base engineered with a thinner cuticle-side zone and flatter everyday curve, a HEMA-free pre-cured gel finish, and premium high-durability jelly tabs that require no liquid nail glue or customer curing lamp.
The finished system
Four layers. Four different jobs.
The finished wearing experience comes from the complete construction, not one premium-sounding material name.
- 01Pre-cured finishHEMA-free gel colour and hand-finished surface.
- 02PMMA baseTapered at the cuticle side for more local flex.
- 03Jelly-tab connectionFlexible, high-durability hold without liquid nail glue.
- 04Natural nailClean, dry, intact and pressure-free before application.
Representative manufacturer data
The raw-material result is not the finished-nail result.
These values compare one named ABS grade with one named PMMA grade. They correct the idea that PMMA is automatically lighter or softer; they do not measure a finished NAILINK nail.

Representative modulus
The customer routine
No liquid glue. No customer curing lamp.
Premium high-durability jelly tabs provide the removable connection. The colour and finish arrive pre-cured.
Start with the whole system, not one ingredient
Material alone cannot prove comfort, and stronger adhesive cannot correct the wrong curve. A useful comparison keeps six decisions connected: base, finish, fit, attachment, real-life movement and removal.
For NAILINK, the result comes from a PMMA base with deliberate thickness distribution, hand-finished pre-cured gel colour, a flatter everyday curve and a removable jelly-tab connection. These are separate parts with separate evidence.
ABS, PMMA and cured soft-gel systems compared
ABS is generally a lower-cost thermoplastic input used for efficient high-volume moulding. PMMA is generally a higher-cost acrylic input chosen for optical clarity, surface hardness and dimensional stability. Soft-gel tip systems are formulation categories rather than one universal chemical grade, so cost and performance vary by formulation, cure and thickness.
Representative manufacturer data show an ABS grade at about 1.04 grams per cubic centimetre and 2,100 megapascals modulus, compared with a PMMA grade at about 1.19 grams per cubic centimetre and 3,300 megapascals modulus. Those grade values do not make a finished-nail decision: geometry can make a thin PMMA press-on feel much lighter and more flexible than a uniformly thick one.
| Decision factor | ABS thermoplastic | PMMA acrylic | Cured soft-gel systems |
|---|---|---|---|
| Typical input cost | $ lower | $$ higher | $$-$$$ formulation-dependent |
| Useful strengths | Impact tolerance and efficient moulding | Clarity, hardness and dimensional stability | Conformability can be designed into a cured system |
| Important limit | Grade and moulding decide bulk, finish and flex | Not inherently lighter or softer than ABS | Not one universal formula, cure or allergy profile |
| Removal | Mainly decided by the attachment layer | Mainly decided by the attachment layer | Depends on whether the specific system is designed to soak off |
Why NAILINK's PMMA base feels lighter and softer-flex
NAILINK deliberately makes the cuticle-side root zone thinner than the main body. That tapered thickness distribution creates more local flex and less raised bulk where the press-on meets the hand. The benefit comes from product geometry, not from claiming that raw PMMA is softer or lighter than ABS.
The base also uses a flatter natural curve developed from nail profiles seen in Australian customer fittings. It is intended to reduce spring-back and pressure on flatter profiles, but it is not a universal-fit claim. Every finger still needs a pressure-free dry fit.
What HEMA-free and pre-cured mean
The NAILINK colour and finishing system is HEMA-free and cured before the finished set reaches the customer. Application therefore requires no wet gel and no UV/LED nail-curing lamp. The full-cover structural base remains PMMA acrylic; gel describes the colour and finishing layers.
HEMA-free does not mean allergy-free. Other acrylates can still sensitise some people, so product contact with surrounding skin should be avoided and irritation is a reason to stop use.
Jelly tabs, liquid nail glue and salon gel adhesive compared
NAILINK uses premium high-durability jelly tabs as its customer attachment system. They provide a flexible pressure-sensitive connection without liquid nail glue. Wear varies with fit, clean and dry preparation, water, oil and hands-on activity, so high-durability is not presented as one fixed day count for every wearer.
The current named jelly-tab sample MSDS reports 90% acrylates copolymer and 10% PET, with MMA and MEHQ not contained. That report applies to the submitted sample and is not a universal allergy or toxicology certificate.
| Decision | Jelly adhesive tab | Liquid cyanoacrylate glue | Salon gel adhesive |
|---|---|---|---|
| Typical input cost | $$ premium tab | $ lower-cost liquid | $$$ product, lamp and tools |
| Customer curing | None | None | UV/LED required |
| Wear character | Flexible and strongly affected by fit and preparation | Firmer bond and strongly affected by dose and preparation | System-specific and usually longer-commitment |
| Removal | Slow warm-water-and-oil release; never pry | Follow the glue and remover instructions | Product-specific soak-off or file-off process |
| Reuse | Often easier when the tip and finish remain sound | Residue removal may reduce reuse | Not usually a removable finished press-on routine |
UV/LED nail lamps: what the evidence supports
UV/LED nail lamps expose the hands to ultraviolet radiation. The American Academy of Dermatology recommends sunscreen or dark fingerless gloves for repeated gel-manicure curing. ARPANSA measured eight home devices and described risk as low at instructed curing times, while noting substantial variation between devices.
The strongest product-specific statement is simpler: NAILINK colour and finish arrive pre-cured, so applying NAILINK adds zero nail-lamp UV exposure to the customer's routine. This does not imply that every correctly timed lamp use causes observable injury.
Removal completes the product system
The NAILINK routine uses no liquid nail glue, drilling, glue scraping or customer acetone soak. Warm soapy water and oil soften the jelly-tab edge; the press-on should be released only where the bond begins to give. If it resists, add time rather than force.
The system is designed for damage-free removal when applied and released as directed. Incorrect fit, covering a compromised nail or forced removal remains outside a universal no-damage guarantee.
Read the evidence boundary before the headline
The jelly-tab MSDS supports the composition and classification of the named submitted sample. The available gel report supports named heavy-metal and microbiology results but does not itself prove HEMA-free or disclose the full formula. The available nail-tip reports support named contaminant results but do not prove polymer identity, thickness, flexibility, curve or cost.
NAILINK therefore labels product specifications, sample reports and general scientific sources separately. This is more useful than one vague whole-product claim such as non-toxic.
Frequently asked questions
What people ask next.
Is PMMA lighter or softer than ABS?
Not inherently. Representative PMMA grades are denser and stiffer than representative ABS grades. NAILINK's lighter, softer-flex wearing feel comes from its tapered cuticle-side zone, thickness distribution and flatter everyday curve.
Why is the NAILINK cuticle edge thinner?
The cuticle-side root zone deliberately uses less material to reduce raised bulk and create more local flex where the press-on meets the hand.
Do NAILINK nails need liquid nail glue?
No. Premium high-durability jelly adhesive tabs are the NAILINK customer attachment system. Wear varies with fit, preparation, water, oil and activity.
Do NAILINK press-on nails need a UV or LED lamp?
No. The HEMA-free gel colour and finish arrive pre-cured, so application requires no nail-curing lamp and adds zero nail-lamp UV exposure to the customer routine.
Are HEMA-free press-on nails allergy-free?
No product should make that leap. HEMA-free means HEMA is not used in the specified colour and finishing system; other acrylates may still sensitise some people. Stop use if irritation occurs.
Can press-on nails be removed without damaging natural nails?
NAILINK is designed for damage-free removal when its jelly tabs are applied and released as directed. The routine needs no drilling, scraping or acetone soak. Never peel or pry a resisting nail.
How long do high-durability jelly tabs last?
They are selected for secure everyday hold, but there is no honest universal day count. Fit, preparation, water, oil and hands-on activity all change the result.
Why does one press-on nail keep lifting?
That finger may need a different width, curve or tab placement. Check the single finger before changing the entire adhesive system.
Can NAILINK press-on nails be reused?
They can be reused when the shape and finish remain intact and old jelly-tab residue releases without scraping. Retire any piece that is cracked, warped, peeling, sharp or contaminated.
