The gel. Everything else in this family is a liquid that will find its way down a vertical face before it cures — 454 does not flow, so it stays exactly where it is put on overhead work, upright joints and porous surfaces that would otherwise drink a thin adhesive. It is also the strongest cyanoacrylate here on steel at 20.9 N/mm², and it bonds the same wide range as 401 including wood, paper, leather and fabric.
Key features
- Thixotropic gel — will not run on vertical or overhead surfaces
- Highest lap shear on steel in this family: 20.9 N/mm²
- 17.1 N/mm² on etched aluminium
- Bonds metals, plastics, elastomers and porous materials
- Non-drip, so it suits porous substrates that absorb a liquid grade
- ≥6.0 N/mm² tensile on Buna-N after 30 seconds
- NSF registered Category P1 for food processing areas (a regional approval)
- Gains strength in petrol, ethanol and isopropanol over 1,000 hours
Typical applications
- Vertical joints
- Porous substrates

Fixture time by substrate
At 22°C and 50% relative humidity — time to develop 0.1 N/mm² shear strength. Being a gel, it fixtures more slowly than the liquids: on steel, 30–60 seconds against under 5 for 401.
| Substrate | Fixture time (seconds) |
|---|
| Rubber, nitrile | <5 |
| ABS | <5 |
| Phenolic | <5 |
| Wood (balsa) | <5 |

How to use it
- Bond areas must be clean and free from grease — clean with a Loctite cleaning solvent and allow to dry.
- On low-energy plastics, a Loctite Primer improves bonding. Do not over-apply; let it dry.
- A Loctite Activator may be used where needed. Apply to one surface only, and not to a primed surface. Let it dry.
- Apply adhesive to one surface — not the activated one. Do not spread it with tissue or a brush.
- Assemble within a few seconds and locate accurately: the short fixture time leaves almost no room to adjust.
- Hold or clamp until fixtured. Activator can be sprayed on excess product outside the joint to cure the fillet.
- Allow full strength to develop before applying service loads — typically 24 to 72 hours.
Handling and storage
- Not recommended for pure oxygen or oxygen-rich systems.
- Not a sealant for chlorine or other strong oxidising materials.
- Store at 2°C to 8°C — cyanoacrylates want refrigeration, unlike the anaerobics which prefer 8–21°C. Outside that range the product properties can be affected.
- Full functional strength comes quickly, but chemical and solvent resistance keeps developing for at least 24 hours.
- Do not return decanted product to the original container.
- Humidity matters: best results at 40–60% RH at 22°C. Lower humidity slows the cure; higher humidity speeds it but can impair final bond strength.
When the gel rather than a liquid?
Reach for 454 whenever gravity is a problem — a vertical face, an overhead joint, or a porous material that would soak up a thin grade before it cures. It is also the strongest here on steel. The trade-off is speed: 30–60 seconds to fixture on steel against under 5 for 401. On a flat bench with metal parts, 401 is faster; for plastics use 406; where the joint will be shocked or peeled, 480.
