Loctite 480 is a one-part ethyl cyanoacrylate that cures on the moisture already present on the parts — no mixing, no heat, no activator needed in normal conditions. What separates it from a standard grade like 401 is the rubber toughening: increased flexibility and peel strength, and markedly better resistance to shock. It is the grade to reach for on metal-to-rubber and metal-to-metal joints that see vibration, impact or intermittent load, and the black colour makes the bond line easy to inspect on dark parts.
Key features
- Rubber toughened — absorbs and spreads impact instead of cracking
- Much higher peel and shock resistance than a standard cyanoacrylate
- Fixtures on steel in 60–120 seconds; on nitrile and neoprene in under 20
- One part, no mixing, cures on ambient moisture at room temperature
- Black bond line, easy to inspect on dark components
- Retains ≥18 N/mm² on grit-blasted steel after 48 hours at 120°C
- Holds 85% of initial strength after 1,000 hours in motor oil at 40°C
Typical applications
- Metal-to-rubber joints subject to vibration or flexing
- Bonding magnets into housings and assemblies
- Close-fitting metal parts under impact or shock loading
- Nitrile, neoprene and EPDM gaskets and seals
- Engineering plastics — ABS, PVC, polycarbonate, phenolic
- Repairs where a standard instant adhesive has already failed brittle

Heat resistance
Cured for 24 hours at 22°C then aged 48 hours at 120°C and tested at 22°C, lap shear on grit-blasted steel remains ≥18 N/mm² (≥2,610 psi). Henkel publishes heat-ageing curves to 120°C; the cured polymer has a glass transition temperature of 150°C.

How to use it
- Surfaces must be clean and free from grease — use the appropriate Loctite cleaner.
- Apply sparingly to one surface only. Excess slows cure and causes blooming.
- Works best in a thin bond gap of about 0.05 mm.
- Assemble immediately and locate accurately — the short fixture time leaves little room to adjust. Hold or clamp until fixtured.
- Where a large gap makes cure too slow, an activator will speed it up, though it can reduce ultimate strength — test first.
- Excess uncured adhesive dissolves with Loctite cleanup solvent, nitromethane or acetone.
Handling and storage
- Not recommended for pure oxygen or oxygen-rich systems.
- Do not use as a sealant for chlorine or other strong oxidising materials.
- Full functional strength develops quickly, but chemical and solvent resistance continues to build for at least 24 hours.
- Store unopened in a dry place. Henkel gives optimal storage as 2°C to 8°C; outside that range product properties can be affected.
- Do not return decanted product to the original container.
Loctite 480 or a standard grade?
If the joint only has to hold, a general-purpose cyanoacrylate is cheaper and faster. Choose 480 when the bond will be shocked, peeled or vibrated — that is exactly where an untoughened grade fails, because a standard cyanoacrylate cures hard and brittle and a crack at the joint edge runs straight through it. The rubber phase in 480 blunts that crack. The trade-off is a slower fixture on steel, 60–120 seconds against roughly 20 for a general-purpose grade, so parts must be held a little longer.
