The Super Gom Precision Gomagom 2 is the maximum-precision cyanoacrylate in the Gomagom family: 3 grams of clear adhesive in a pen-style applicator with an extra-fine tip, designed for jobs where a normal drop of superglue is already too much material. It's the format jewellers use to set gems in mounts, modellers use to fix photo-etched parts and micrometric elements on scale models, and makers use for tiny joins on 3D printed parts with very fine details. The manufacturer itself illustrates it with an image of a ring with a gemstone — that's exactly its natural use case. For normal-sized 3D printed parts or general assemblies, you're better off with Gomagom 9 (brush applicator, 10 g) or Gomagom 7 (conical nozzle, 20 g).
Why the pen format changes micro-precision work
There's a level of detail where both the conical nozzle and the brush are too big. Gluing a 2 mm gem to a mount prong, fixing a photo-etched part on an N-scale train, attaching rigging line to a mast in ship modelling, repairing the broken arm of a pair of glasses, or fitting a 3D printed part with sub-millimetre details — these are scenarios where the problem is NOT the bonding strength of the cyanoacrylate (any brand delivers), but application control.
Gomagom 2 solves this with a pen-style applicator and an extra-fine tip. The application area is reduced to roughly half a millimetre, letting you effortlessly deposit a literal pinhead-sized dot of adhesive. You apply exactly where you need it, without spilling onto adjacent parts or smudging delicate finishes.
Typical use cases
Gomagom 2 shines in scenarios where application control matters more than the amount of adhesive:
Jewellery: gluing gems, pearls and decorative elements to mounts. The packaging itself shows this as its main use. The extra-fine tip deposits the minimum amount needed without the adhesive spreading onto the visible face of the gem or the mount.
N, Z, HO and similar scale modelling with micrometric details. Fixing railings, photo-etched parts, rigging lines, electrical connections and cockpit details on scale models where elements are around a millimetre in size.
3D printed parts with ultra-fine details. Assemblies of sub-millimetre geometries that appear mainly on high-resolution UV resin printers (Mono X 4K, Saturn Ultra, Photon Mono M5s, etc.). Gluing tiny neodymium magnets, printed connectors, joints on articulated models, etc.
Repairs to small, delicate objects. Glasses arms, handles on fine porcelain cups, non-mechanical watch parts, corners of small frames, toys with tiny elements.
Small-scale figure modelling. 28-32 mm scale miniatures have standard details that the Gomagom 9 brush handles well; for smaller scales (15 mm, 6 mm, historical scales), the Gomagom 2 pen gives you more control.
Which Gomagom adhesive to choose for your job
We stock several adhesives from the Gomagom family, each optimised for a different scenario:
-
Gomagom 2 (this one, liquid, 3 g, extra-fine pen): maximum precision. Jewellery, photo-etched parts, fine-scale modelling, sub-millimetre details.
-
Gomagom 9 (liquid, 10 g, brush applicator): moderate precision. Wargaming miniatures, assemblies with fine details, small printed parts.
-
Gomagom 7 (liquid, 20 g, conical nozzle): general use. Assembling large printed parts, workshop repairs, household use.
-
Gomagom 37 (GEL, 3 g, anti-clog applicator): difficult joins. Vertical applications, porous materials, neodymium magnets, where liquid would run.
-
Gomagom 87 (UV resin, 4 g, with UV torch): SLA part repair. Superior chemical affinity with UV resin printed parts.
Advanced 3D printing and modelling hobbyists end up with several formats in the drawer, each for its own type of job. They're not substitutes: they're complementary.
How to use it
The procedure is standard for any cyanoacrylate — the pen applicator only changes how you apply it:
1. Clean, dry surfaces. Both parts to be joined must be free of dust, grease and residue. In jewellery, wiping the mount and the base of the gem with isopropyl alcohol before gluing noticeably improves adhesion.
2. Apply a tiny dot of adhesive with the pen tip. With cyanoacrylate, less is more. On parts as small as those that justify this format, you'll usually need literally a fraction of a drop. The extra-fine tip deposits the minimum amount.
3. Join and press for 15-30 seconds. This is the standard initial setting time for cyanoacrylate. Hold the parts in position without moving them during this time. In jewellery with small gems, precision tweezers are very useful for holding position without touching the visible face.
4. Maximum strength after around 12 hours. For pieces that will be handled or worn (rings, earrings), it's best to wait until the next day before demanding full strength.
As with any cyanoacrylate, avoid contact with your fingers when joining parts. If your fingers get stuck, use Gomagom 21 Adhesive Remover.
Material compatibility
According to the manufacturer's official safety data sheet, Gomagom 2 bonds:
- Rigid plastics (including PLA, PETG, ABS and cured UV resin)
- Ceramic and porcelain
- Rubber
- Hardwoods
- Marble
- Metals (gold, silver, steel, brass — jewellery base)
- Mother-of-pearl

Why buy it at Mr Resin
It's not the cyanoacrylate you'll go through every week — it's the cyanoacrylate that sits in the drawer for that occasional moment of the year when you're gluing a tiny gem, building an N-scale model or repairing something with very fine detail. For those moments, having it at hand is the difference between finishing the job in 5 minutes or smearing the part trying to apply superglue with a toothpick. If you're already ordering resin, filament or paint, adding it to your cart ships in the same parcel at no extra cost. Shipping to mainland Spain is free from 79 €.
Mr Resin has been serving over 5,000 makers in Spain, Portugal and France for years. Our catalogue is built around what the community asks for: printers and materials as the core, plus the workshop consumables that end up being part of everyday work.
Frequently asked questions
Can it be used to glue gems in jewellery?
Yes, it's one of its best use cases, and the manufacturer's own packaging shows it as the main application with an image of a ring with a stone. The extra-fine tip deposits the minimum amount without the adhesive spreading onto the visible face of the gem or the rest of the mount. For silver or gold jewellery, we recommend cleaning the surfaces beforehand with isopropyl alcohol to improve adhesion.
How is it different from the Gomagom 9 with brush?
In the application area. The Gomagom 9 brush covers an area of around 2-3 mm — perfect for wargaming miniatures and standard-detail assemblies. The Gomagom 2 pen covers an area of roughly half a millimetre — necessary for jewellery, fine-scale modelling photo-etched parts and printed parts with sub-millimetre details. If your work is at the level of 28-32 mm scale miniatures or standard printed part assemblies, the 9 is enough. If you work below that level of detail, the 2 is the right choice.
Does it work on UV resin printed parts?
Yes, it works like any cyanoacrylate on cured UV resin. It's particularly useful for assembling printed parts with ultra-fine details that are only possible with high-resolution SLA printers. We recommend properly washing and curing the parts, and wiping the contact surfaces with isopropyl alcohol before applying.
Why only 3 g if it seems so little?
Because in the uses this format is designed for — jewellery, photo-etched parts, micro-precision — consumption per job is minimal. A single jewellery application can use the equivalent of a tenth of a drop. A 3 g tube can last you dozens or hundreds of spot applications before you need to restock. If your use requires more volume because you work with large parts, this isn't the right format and you should look at the 20 g Gomagom 7.
How long does the tube last once opened?
Like any cyanoacrylate, once opened it starts losing properties by absorbing ambient humidity. Stored correctly between 5 and 25 °C, in a cool, dry place away from sunlight (the safety data sheet explicitly states this), a tube can last you many months with occasional use. Always close the applicator tightly after each use.
What if my fingers get stuck?
Standard procedure for any cyanoacrylate: don't pull them apart by force (it tears off layers of skin), apply Gomagom 21 Adhesive Remover to the bonded area, wait 2-4 minutes and gently separate. Any residue can be removed by washing with soap and water. If the situation is serious (eyes, wounds, children), seek medical attention.
