The Cyanoacrylate Accelerator Spray is the essential companion for working with cyanoacrylate adhesives when you need a truly instant bond. Apply it to one surface before applying the cyanoacrylate to the other and both parts bond the moment they make contact — no waiting. Ideal in the workshop for accelerating cure on difficult parts, production assemblies or repairs where time matters.

What it is used for
The accelerator spray is designed to reduce cyanoacrylate set time to zero, which is especially useful when working with parts you cannot hold in position for long, porous surfaces, or when you need production throughput. It is also very effective combined with Ciano Denso, which due to its viscosity cures somewhat more slowly and benefits from the accelerator to compensate.
- Fast assembly of parts in resin, polyurethane or composite
- Instant bonding of parts in foam, cork, wood or leather
- Urgent repairs in special effects and prosthetics workshops
- Bonding small parts that cannot be held under prolonged pressure
- Combination with Ciano Denso to accelerate its slower cure
- Series production where cycle time is critical
- Sealing and bonding porous materials that absorb the adhesive
How to use it
- Make sure both surfaces to be bonded are clean, dry and free of dust or grease.
- Shake the spray can before use.
- Spray the accelerator onto one of the two surfaces to be bonded, from a distance of approximately 15–20 cm.
- Wait a few seconds for the accelerator solvent to evaporate completely (the surface loses its wet sheen).
- Apply a small amount of cyanoacrylate — Ciano Normal, Ciano Muy Líquido or Ciano Denso — onto the other surface.
- Bring both surfaces together with positioning precision, as the grip is virtually immediate.
- Apply firm pressure for 5–10 seconds to secure the bond.
Caution: The spray contains volatile and flammable solvents. Always use in well-ventilated spaces, away from flames or heat sources. Avoid contact with eyes and skin. Cyanoacrylate can bond fingers instantly: if this happens, do not force separation. The accelerator also speeds up setting if cyanoacrylate spills on skin, so wear nitrile gloves whenever possible.
Usage tips
Use just the right amount of accelerator
Less is more. Excess accelerator can leave a whitish residue at the joint and in some cases weaken the bond. A light, even mist is sufficient. If you see too much liquid remaining on the surface, wait longer for it to evaporate before joining.
Match the cyanoacrylate to the material
For highly porous materials (foam, untreated wood, cork), Ciano Denso penetrates less and leaves more material at the joint; the accelerator compensates for its slower cure. For smooth, non-porous surfaces, Ciano Muy Líquido with accelerator gives very clean and strong bonds.
Storage and shelf life
Store the spray upright, in a cool place away from direct light. Heat and humidity degrade the accelerator over time. If the spray begins to discharge with low pressure or unevenly, it is a sign the can is nearly empty: it is better not to force it and to replace it to ensure consistent results.
Frequently asked questions
Is it mandatory to use the accelerator with cyanoacrylate adhesives?
It is not mandatory. Cyanoacrylates cure on their own by reacting with ambient moisture. The cyanoacrylate accelerator spray is used when you need an instant bond or when working with very dry or low-reactivity surfaces where natural curing would be too slow.
Can I apply the accelerator and the cyanoacrylate on the same surface?
No. The accelerator and the cyanoacrylate must be applied to separate surfaces. If you mix them on the same side before joining, the cyanoacrylate will set before you can position the parts and the bond will be poor or non-existent.
How long do I have to join the parts after applying the accelerator?
The accelerator remains active for several minutes once the solvent has evaporated. However, the optimum is to join within the first 1–2 minutes after evaporation to get the best performance.
What materials does the accelerator work with?
The cyanoacrylate accelerator spray is compatible with all materials that accept cyanoacrylate adhesives: metals, plastics (ABS, PVC, polystyrene), cured resins, wood, ceramics, leather, rubber and rigid foams. Always test on a hidden area if the material is delicate, as the spray solvent may affect some soft plastics or paints.
Does the accelerator leave a mark or stain on the part?
If applied in excess or not allowed to evaporate properly, a whitish residue may remain around the joint. By applying a minimal amount and waiting for complete evaporation, the result is clean with no visible marks.
Can the accelerator be used with any type of cyanoacrylate?
What should I do if my fingers get bonded together?
Do not force separation. Soak the area in warm soapy water, or use pure acetone to dissolve the cyanoacrylate. Work with gentle movements and patience. If the skin is compromised or there is pain, consult a doctor.
Where can I buy standard cyanoacrylate?
You can find Feroca's Ciano Normal directly in our online store. We also carry a very thin and a thick version depending on your needs.
