Gomagom 37 Gel Adhesive 3g | Vertical Gel Cyanoacrylate Glue for 3D Printing

The Gomagom 37 Super Gom Applicator GEL is the gel format cyanoacrylate from the Gomagom family: 3 g of clear adhesive with a built-in applicator and anti-clog cap, designed for the situations where liquid CA glue falls short. The gel formula doesn't run, doesn't absorb into porous surfaces, and stays put on vertical or overhead applications — making it the right choice for bonding 3D printed parts on difficult joints, securing elements to vertical surfaces without dripping, and working with flexible materials, leather, rubber, or porous wood where liquid cyanoacrylate evaporates before it can cure. If you're working on horizontal surfaces with clean joints, liquid CA glues are still faster: Gomagom 7 for general use, Gomagom 9 with brush for precision, Gomagom 2 with pen tip for maximum precision.

Why gel format changes the game

The difference between liquid and gel cyanoacrylate isn't cosmetic — they're adhesives with fundamentally different behavior. Liquid CA is very fluid, cures extremely fast, and performs best on clean joints between horizontal surfaces in full contact. Gel CA is viscous, doesn't drip, doesn't absorb, and lets you work in situations where liquid is physically impractical.

No dripping. When you apply to a vertical surface — a raised arm on a miniature, a side detail on a printed part, a bracket being glued to a wall — the gel stays exactly where you put it. Liquid CA runs down by gravity before you have time to join the pieces.

Doesn't absorb into porous surfaces. Untreated wood, leather, MDF, cardboard. Liquid cyanoacrylate wicks into the pores, leaving insufficient material at the surface to form a bond. Gel stays where you apply it.

Longer working time. Gel takes slightly longer to cure (still 15–30 seconds), giving you extra time to adjust the position of your piece before the bond becomes permanent.

Fills small gaps. On joints where two surfaces don't fit together perfectly, the gel can fill minor gaps that liquid CA would leave empty (capillary action actually pulls liquid away from gaps). It's not a substitute for epoxy putty on large gaps, but it does help with small imperfect joints.

Typical use cases in 3D printing

The Gomagom 37 covers common workshop scenarios where liquid cyanoacrylate comes up short:

Assembling multi-part prints with vertical or angled joints. With multipart resin or PLA prints, you can't always lay the piece flat on the table: sometimes you need to bond at a vertical angle to maintain alignment, or assemble after part of the model is already mounted in its final position. Gel lets you apply without it running before you join the parts.

Setting neodymium magnets in printed parts. For modular parts with magnetic connections, you need to secure magnets in small cavities. Gel CA stays in the cavity without flooding the surrounding area or dripping, and gives you time to adjust the magnet's orientation before the bond sets.

Repairing joints with minor imperfections. When a printed part doesn't fit perfectly with its counterpart — slightly loose fit, layer separation at the contact zone — gel helps fill the fractions of a millimeter that liquid CA would leave as a gap. For larger gaps, epoxy putty like Gomagom 31 is a better option.

Working with flexible filament prints. TPU and other flexible materials have poor affinity with liquid cyanoacrylate, which tends not to bond well. Gel formula performs somewhat better on these materials — though it's still not ideal. For critical TPU bonds, you'll need a purpose-specific flexible adhesive.

Bonding painted surfaces or primed parts. Liquid formula tends to run across the finish and leave visible marks. Gel deposits a controlled drop that stays exactly where you apply it.

Use cases in scale modeling and crafts

Beyond 3D printing, gel format is the right choice for:

Scale models with difficult joints. Vertical structural details, photo-etched parts on non-horizontal surfaces, connections where the piece won't stay in position on its own. Works alongside Gomagom 20 Modeling Adhesive in situations where you need fast bonding without waiting for polystyrene cement to cure.

Leather and rigid textile materials. Bag repairs, belts, cases, footwear. Liquid cyanoacrylate soaks into the material and doesn't leave enough adhesive at the surface to create a solid bond — gel stays where you put it.

Porous wood, MDF, and DIY crafts. Same principle: gel won't get absorbed into the grain the way liquid formula does.

Vertical household repairs. Re-adhering a loose tile, fixing a broken handle back onto a mug in vertical position, any repair where you need the adhesive to stay put while it cures.

Which Gomagom adhesive is right for your project

A quick-reference guide to choosing within the Gomagom range:

• Gomagom 7 (liquid, 20 g, conical tip): general purpose. Large assemblies, workshop repairs, everyday household use.
• Gomagom 9 (liquid, 10 g, brush applicator): moderate precision. Miniatures, detailed assemblies, small printed parts.
• Gomagom 2 (liquid, 3 g, pen applicator): maximum precision. Jewelry, photo-etched details, sub-millimeter work.
• Gomagom 37 (this one — GEL, 3 g, anti-clog applicator): vertical surfaces, flexible or porous materials, imperfect joints, neodymium magnets in printed parts, any situation where liquid formula would run or soak in.
• Gomagom 87 (UV resin adhesive, 4 g, with UV flashlight): repairing UV resin prints with superior chemical affinity, extended working time, bonds where one surface is transparent.

These aren't interchangeable — each one is designed for a different type of work. Any active 3D printing or modeling workshop ends up keeping several formats on hand.

How to use it

Application instructions per the manufacturer's label:

1. Start with clean, dry, dust-free and grease-free surfaces. A quick wipe with isopropyl alcohol significantly improves adhesion — especially on UV resin prints (removing monomer residue) and porous materials (clearing deep-seated dust from the pores).

2. Apply a small amount of gel — one drop is enough. The manufacturer states this explicitly: applying too much reduces both bond strength and cure speed. The gel texture makes it easy to control how much you apply without it running when you squeeze the tube.

3. Join the parts while avoiding skin contact. Cyanoacrylate bonds skin to skin within seconds.

4. Hold for 15–30 seconds. This is the initial setting time. Maximum bond strength is reached at around 12 hours.

5. After use: clean any residue from the applicator with an adhesive remover. The manufacturer specifically recommends this to prevent clogging. Gomagom 21 Adhesive Remover is exactly what you need for this. Close the cap tightly and store in a cool, dry place away from light.

If your fingers get bonded together, the process is the same as with any cyanoacrylate: apply adhesive remover, wait 2–4 minutes, and gently pull apart.

Material Compatibility

According to the official product label, Gomagom 37 bonds:

• Rigid plastics (PLA, PETG, ABS, cured UV resin, HIPS for scale models)
• Ceramic and porcelain

Frequently Asked Questions

What's the difference between gel cyanoacrylate and liquid cyanoacrylate?
Viscosity. Liquid CA glue is very thin, bonds almost instantly, and works best for horizontal joints with full surface contact. Gel CA is thick, doesn't drip, won't soak into porous surfaces, and can be applied vertically without running. For clean bonds between two flat horizontal surfaces, liquid is faster. For angled or vertical surfaces, porous materials, or imperfect joints, gel is the right choice.

Can I use it to glue 3D printed parts together?
Yes. Cyanoacrylate is the go-to adhesive for 3D printed parts (PLA, PETG, ABS, UV-cured resin), and the gel formula is especially useful when bonding vertical surfaces, when the contact area isn't perfectly flat (common with visible layer lines), or when gluing small details in spots where you don't want the adhesive to run outside the application area.

Does it work for gluing neodymium magnets into printed parts?
Yes, this is one of its most common uses in 3D printing. The gel texture stays put inside the magnet pocket without spreading into surrounding areas, and gives you a few seconds to adjust the magnet's position before it sets. For magnet joints that will face repeated high magnetic force, consider reinforcing with epoxy putty inside the cavity for added mechanical strength.

Why only 3 g?
Because this format is designed for occasional use — specifically for situations where standard liquid CA glue isn't the right tool. For everyday cyanoacrylate use in the workshop, a larger liquid format offers better value per gram — we carry the Gomagom 7 in 20 g for that. The 37 is the gel you reach for when you need it, not your daily-driver CA glue.

Does the anti-clog cap actually work?
The manufacturer highlights it as a key product feature, and the label instructions spell it out explicitly: "Clean adhesive residue from the applicator with an adhesive cleaner" before closing the cap. In other words, the cap is engineered to resist clogging — but it does require
