Quick answer — Loctite 480 essentials
What it is: Loctite 480 is a black, rubber-toughened ethyl cyanoacrylate ("super glue") instant adhesive, built for joints that take a knock — shock, vibration and peel loading — rather than static assemblies alone.
Cure time: Fixtures in under 20 seconds on neoprene and nitrile rubber, 10–30 seconds on aluminium, and 60–120 seconds on degreased steel. Full chemical/solvent resistance develops over at least 24 hours.
What it bonds: Metals, plastics and rubbers, with genuine impact and peel resistance once cured. Doesn't suit: visible joints (cures black) · applications needing the absolute highest shear strength · gaps beyond a thin bond line.
Loctite 480 vs 401 vs 406 vs 454: 480 = rubber-toughened, for shock and vibration. 401 = general purpose, medium viscosity. 406 = low viscosity, for plastics and rubber specifically. 454 = gel, for gap-filling and porous materials.
Loctite 480 is the Prism-range instant adhesive AIMS reaches for when a cyanoacrylate joint needs to survive more than a static bench test — dynamic loading, shock, vibration, or a joint that gets flexed or knocked in service. Standard instant adhesives like 401 and 406 produce a rigid bond line that's strong under pure shear but brittle under impact or peel. 480's rubber-toughening trades a little raw shear strength for genuine flexibility and impact resistance, which is exactly what a lot of maintenance and assembly work actually needs.
This guide covers what Loctite 480 is, exactly what it bonds and how well, how it compares to 401 and 406, and how to apply, troubleshoot and remove it — sourced from AIMS's own product data and Henkel's published Technical Data Sheet, not generic marketing copy.
What Is Loctite 480?
Loctite 480 is a rubber-toughened ethyl cyanoacrylate instant adhesive — the same cyanoacrylate chemistry as 401 and 406, but formulated with a rubber-toughening agent that gives the cured bond increased flexibility, peel strength and shock resistance. It's part of Henkel's Prism range of industrial instant adhesives, alongside 401 and 406. The trade-off for that toughness is colour: 480 cures black, rather than clear, and its recommended bond gap is thinner than a general-purpose grade.
Like all cyanoacrylates, it cures by reacting with trace atmospheric moisture — no mixing, no clamping equipment, no cure oven required. Full functional strength develops quickly, but curing continues for at least 24 hours before full chemical and solvent resistance is reached.
Loctite 480 — Quick Reference
| Property | Value |
|---|---|
| Chemistry | Ethyl cyanoacrylate, rubber-toughened (one-part, moisture-cured) |
| Appearance | Black liquid |
| Viscosity | 100–200 mPa·s — low-to-medium |
| Specific gravity | 1.05 at 25°C |
| Fixture time — steel | 60–120 seconds (AIMS product data: ~90 seconds representative) |
| Fixture time — neoprene, nitrile rubber | Under 20 seconds |
| Full cure | At least 24 hours for full chemical/solvent resistance |
| Operating temperature | –40°C to +100°C |
| Shear strength — steel | 22–30 N/mm² (3,200–4,400 psi); AIMS product data: 26.0 N/mm² |
| Max gap fill | 0.18 mm (AIMS spec) — TDS notes best performance in thin bond lines around 0.05 mm |
| Bonds well | Metals, plastics and rubbers where impact or peel resistance matters |
| Trade-off vs 401/406 | Lower raw shear strength on rigid substrates in exchange for flexibility and shock resistance; cures black |

Fixture Time by Substrate
⚠️ Verify before specifying: Figures below are drawn from Henkel's published Technical Data Sheet (fixture time to reach 0.1 N/mm² shear strength, 22°C / 50% RH) and AIMS's own product data. Always confirm against the current TDS before use in a critical or regulated application.
| Substrate | Fixture Time |
|---|---|
| Neoprene | Under 20 seconds |
| Nitrile rubber | Under 20 seconds |
| Aluminium | 10–30 seconds |
| Phenolic | 20–60 seconds |
| ABS | 20–50 seconds |
| Polycarbonate | 30–90 seconds |
| Zinc dichromate | 50–150 seconds |
| PVC | 50–100 seconds |
| Steel (degreased) | 60–120 seconds |
480 fixtures noticeably slower on steel than 401 or 406 do — that's the rubber-toughening trading assembly speed for a bond that tolerates impact and flex. If fast handling on plain steel is the priority and the joint won't see shock loading, 401 is the more efficient choice.
Lap Shear Strength by Substrate
Measured to ISO 4587, 24 hours after assembly at 22°C.
| Substrate | Shear Strength |
|---|---|
| Steel (grit blasted) | 22–30 N/mm² (3,200–4,400 psi) |
| Aluminium (etched) | 14–22 N/mm² (2,000–3,200 psi) |
| Polycarbonate | 5–20 N/mm² (730–2,900 psi) |
| ABS | 6–20 N/mm² (870–2,900 psi) |
| Zinc dichromate | 8–15 N/mm² (1,200–2,200 psi) |
| Phenolic | 5–15 N/mm² (730–2,200 psi) |
| Nitrile | 5–15 N/mm² (730–2,200 psi) |
| Neoprene | 5–15 N/mm² (730–2,200 psi) |
| PVC | 4–20 N/mm² (580–2,900 psi) |
On steel, 480's shear strength (22–30 N/mm²) is actually competitive with a general-purpose grade — the difference isn't raw strength so much as what the bond does under a shock or peel load rather than steady shear. One data point worth knowing: after 24 hours' cure followed by 48 hours at 120°C, tested back at 22°C, Henkel's own published data shows steel lap shear strength holding at 18.0 N/mm² or better — a useful indicator that a 480 bond isn't fragile after a heat excursion.
Environmental Resistance: Heat and Chemical Exposure
This is the data that determines whether a 480 bond survives in service, not just on the bench.
Hot strength (mild steel, tested at temperature): published data shows strength holding close to its room-temperature value up to around 50°C, then declining as temperature rises further — reaching roughly half of room-temperature strength in the 90–100°C region and continuing to taper toward the upper end of the –40°C to +100°C operating range. Treat the published operating ceiling as a limit, not a level where full bench strength still applies.
Heat ageing (aged at temperature, then tested at 22°C, tracked out to 5,000 hours): at 80°C, strength stays close to its initial level across the full test window. At 100°C, strength declines gradually over the 5,000-hour period. At 120°C, the decline is much steeper, with most of the strength loss happening within the first 1,000–1,500 hours of exposure. The published chart is a trend line rather than a numbered table — for a joint running continuously above 80°C, checking the current TDS chart directly (or asking AIMS) is worth doing before finalising a design.
Chemical exposure (percentage of initial strength, aged then tested at 22°C, on steel):
| Environment | 100 hrs | 500 hrs | 1,000 hrs |
|---|---|---|---|
| Motor oil (40°C) | 85% | 85% | 85% |
| Gasoline (22°C) | 90% | 70% | 70% |
| Ethanol (22°C) | 95% | 95% | 80% |
| Isopropanol (22°C) | 75% | 75% | 75% |
| Freon TA (22°C) | 90% | 90% | 85% |
| Heat/humidity (95% RH, 40°C) | 80% | 80% | 65% |
Polycarbonate is the standout case: tested under the same heat/humidity conditions (95% RH, 40°C), a 480 bond on polycarbonate retains 100% of its initial strength across the full 1,000-hour test — noticeably better than the same exposure on steel. For polycarbonate assemblies exposed to sustained heat and humidity, that's a useful data point in 480's favour.
What this means for selection: motor oil and Freon exposure barely move the needle on 480, gasoline and high humidity cost more over time, and steel joints under continuous high humidity should be designed assuming roughly two-thirds of bench strength applies long-term rather than the full published figure.
Loctite 480 vs 401 vs 406 vs 454 — Which Do You Need?
| Product | Viscosity | Best For | Key Feature | Avoid For |
|---|---|---|---|---|
| 480 | Low-medium (100–200 mPa·s, black) | Dynamic assemblies subject to shock, vibration, peel or impact | Rubber-toughened; flexible, impact-resistant bond | Visible joints (cures black); where maximum raw shear strength is the only priority |
| 401 | Medium (100–120 mPa·s) | Metals, rigid plastics, rubber, porous materials — general purpose | Surface-insensitive; works on chromated & acidic surfaces | Dynamic loading; PE, PP, PTFE without primer |
| 406 | Low (~20 mPa·s) | Rubbers, ABS, PVC, polycarbonate and other difficult plastics | Surface-active ingredient for low-energy plastics and elastomers | Dynamic loading; large gaps |
| 454 | High, thixotropic gel | Vertical/overhead joints, gap-filling repairs, porous materials — wood, paper, leather, fabric | Won't run, drip or wick away; non-drip gel | Dynamic loading; rubber-to-rubber bonds needing max shear strength |
Default choice rule: reach for 480 when the assembly will see shock, vibration, or repeated flexing in service — a rigid 401 or 406 bond line is more likely to crack under that kind of load. Use 401 for static, general-purpose metal and mixed-substrate work. Use 406 for static bonding on rubbers and difficult plastics. Use 454 gel where the joint is vertical, overhead, gap-filling, or on a porous material like wood, leather or fabric — none of which is what 480 is built for. If the joint is both plastic/rubber and dynamically loaded, 480 still bonds all three material families — check the substrate-specific shear figures above against 406's to weigh the trade-off for your specific case.

What Changes 480's Cure Speed
Bond gap
Thinner bond lines cure faster. Henkel's own guidance is that 480 performs best in thin bond gaps around 0.05 mm — AIMS's published maximum gap fill is 0.18 mm, but the thinner end of that range gives the fastest, most reliable cure.
Relative humidity
Cure speed tracks ambient humidity. Testing on Buna-N rubber shows full cured strength developing fastest at 60% RH, more slowly at 40% RH, and slowest at 20% RH. In a dry workshop environment, expect cure to take longer than the headline fixture-time figures suggest.
Accelerator
Where cure speed is unacceptably slow because of a larger gap, an accelerator applied to the bond surface will speed things up — but Henkel's own guidance is direct about the trade-off: this can reduce the ultimate strength of the bond, so testing is recommended to confirm the effect before relying on it for a load-bearing joint.
How to Apply Loctite 480
- Clean both surfaces. Remove oil, grease, dust and release agents with Loctite SF 7063 general purpose cleaner or isopropanol. Dry completely — surface contamination is the most common cause of bond failure.
- Check the fit. 480 performs best in thin bond gaps around 0.05 mm, up to a maximum of 0.18 mm. It is not a gap filler — address poor-fitting surfaces before bonding.
- Apply adhesive to one surface only. A thin film is sufficient. Excess adhesive slows cure, reduces strength, and increases the risk of bloom (white residue).
- Assemble immediately and hold firm contact. Position parts accurately before contact — the short fixture time on rubber and aluminium leaves little room for adjustment.
- Respect fixture time before handling. Neoprene and nitrile fixture in under 20 seconds; steel needs 60–120 seconds. Allow at least 24 hours before the joint sees full chemical or solvent exposure, or full design load.
- Remove excess adhesive promptly. Uncured 480 wipes off with Loctite SF 7063 or acetone before it cures.
⚠️ Skin contact: Cyanoacrylate bonds skin immediately. Wear nitrile gloves. If skin bonding occurs, soak in warm soapy water and gently peel apart — don't pull forcefully. Acetone applied after soaking helps separate bonded skin. Eye contact requires immediate flushing with water and medical review.
Common Failures and How to Fix Them
Bond feels weaker than a 401 or 406 joint on the same substrate
Cause: that's expected, not a defect — 480 trades some raw shear strength for flexibility and impact resistance. If the joint isn't subject to shock or vibration, a general-purpose grade will often out-perform 480 on pure shear.
Fix: if maximum static shear strength is the actual requirement and the joint doesn't see dynamic loading, 401 or 406 may be the better-suited product.
Slow cure, especially in a dry workshop
Cause: 480's cure rate is humidity-dependent, and low relative humidity (around 20% RH) noticeably slows it down compared with 40–60% RH.
Fix: if the workshop is consistently dry, allow longer fixture and cure times than the headline figures suggest, or consider an accelerator — understanding the strength trade-off that comes with it.
White residue (bloom) around the joint
Cause: excess adhesive vapour reacting with atmospheric moisture and depositing as white polymer residue nearby.
Fix: use less product — a thin film is sufficient. Improve ventilation. Bloom is cosmetic, not structural.
Bond fails under sustained heat or humidity
Cause: the environmental resistance data above shows real strength loss under prolonged high humidity or elevated temperature, particularly on steel.
Fix: design joints with this de-rating in mind — for polycarbonate substrates under sustained heat/humidity, 480 holds up better than it does on steel, so substrate choice matters here too.
Visible black bond line on an assembly that needed to look clean
Cause: 480 always cures black — this is inherent to the rubber-toughening formulation, not a fault.
Fix: if appearance matters and the joint doesn't need impact resistance, 401 (clear) or 406 (clear) are the better choice.
Removing Loctite 480
Mechanical removal (metal or rigid assemblies): apply heat with a hot air gun. Cured cyanoacrylate softens with heat — once softened, pry apart with a flat tool. Clean and degrease the bond area with Loctite SF 7063 before re-bonding.
Uncured product: wipes off cleanly with Loctite SF 7063 or acetone before it cures.
AIMS doesn't currently stock a dedicated chemical cyanoacrylate debonder — for a fully cured bond on a substrate that can't take heat, mechanical separation or replacement of the bonded part is the practical option; check with AIMS if a specific debonding chemical is needed for your application.
Typical Applications in Industrial Settings
Assemblies subject to shock or vibration
Bonding components on mobile plant, vehicles and machinery where the joint experiences ongoing vibration. Attaching brackets, guards and fittings in environments where knocks are routine rather than exceptional.
Rubber and elastomer bonding under dynamic load
Anti-vibration mounts, rubber bumpers and feet subject to repeated flexing, where a rigid 401 or 406 bond line would eventually crack.
Maintenance and repair
Field repairs on equipment that will go straight back into service under load, rather than sitting static on a bench — where impact resistance from day one matters more than maximum shear strength.
What Loctite 480 is not suited for
Structural, load-bearing joints where maximum shear strength is the only requirement (use 401 or a structural epoxy). Visible joints where a black bond line is unacceptable (use 401 or 406). Joints loaded in peel beyond what the rubber-toughening is designed to absorb — cyanoacrylates remain fundamentally weak in peel compared with epoxies. Large gaps beyond a thin bond line.
Loctite 480 Storage and Shelf Life
| Condition | Guidance |
|---|---|
| Storage temperature | 2–8°C — performance is adversely affected outside this range |
| Container | Store unopened in a dry location; do not return removed product to the original container |
| Best humidity for application | 40–60% RH — lower humidity slows cure, higher humidity can reduce final strength |
| Keep away from | Direct sunlight, heat sources, and prolonged exposure outside the 2–8°C range |
If the adhesive is stringing, gelling, or producing noticeably poorer bonds than expected, the product has likely degraded from incorrect storage and should be replaced — don't rely on out-of-condition product for a joint that matters.

Frequently Asked Questions
What is Loctite 480 used for?
Loctite 480 is a rubber-toughened instant adhesive used where a joint needs to survive shock, vibration or impact rather than just static loading. Typical uses include bonding components on mobile plant and vehicles, anti-vibration mounts and rubber feet, brackets and fittings in environments prone to knocks, and any assembly where a standard rigid cyanoacrylate bond line would be at risk of cracking in service.
Is Loctite 480 waterproof or resistant to moisture?
Reasonably, but with some de-rating over time. Published data for sustained high humidity (95% RH at 40°C) shows a cured 480 bond on steel retaining around 65% of initial strength after 1,000 hours, while the same test on polycarbonate retains 100%. That's suitable for equipment that gets wet or lives in a humid environment, but for a joint that will be permanently submerged, check the specific exposure conditions against the environmental resistance data above before committing to it.
Is Loctite 480 superglue?
Same underlying chemistry — ethyl cyanoacrylate, the same family as consumer super glue — but 480 is an industrial rubber-toughened formulation with published, substrate-specific fixture time, shear strength, and environmental resistance data that consumer super glue doesn't carry. It's also formulated for a different job: flexibility and impact resistance rather than pure static bond strength.
What is the difference between Loctite 406 and 480?
406 is a low-viscosity, rigid-bond formula built for difficult plastics and rubber under static loading. 480 is rubber-toughened and flexible, built to survive shock, vibration and dynamic loading — at the cost of some raw shear strength on rigid substrates, and it cures black rather than clear. Choose 406 for a strong, low-visibility static bond on plastic or rubber; choose 480 where the joint will be shaken, knocked or flexed in service.
How long does Loctite 480 take to cure (dry)?
Fixture time depends heavily on substrate: under 20 seconds on neoprene and nitrile rubber, 10–30 seconds on aluminium, 20–90 seconds on ABS, phenolic and polycarbonate, and 60–120 seconds on degreased steel. Full chemical and solvent resistance develops over at least 24 hours — don't load a joint to full design strength before that window has passed.
What temperature range can Loctite 480 handle once cured?
The rated operating range is –40°C to +100°C. Published hot-strength data shows strength holding close to its room-temperature value up to around 50°C, then tapering as temperature climbs toward the upper end of that range — so treat the 100°C ceiling as a limit, not a point where full bench strength still applies.
What is the shear strength of Loctite 480?
It varies by substrate: 22–30 N/mm² on grit-blasted steel (AIMS product data cites 26.0 N/mm² as representative), 14–22 N/mm² on etched aluminium, 5–20 N/mm² on polycarbonate, and roughly 5–15 N/mm² on nitrile and neoprene rubber. On steel, that's competitive with a general-purpose cyanoacrylate — the real difference from 401 or 406 is how the bond behaves under impact and peel, not raw shear numbers.
Will Loctite 480 fill gaps in an uneven joint?
No — AIMS's rated maximum gap fill is 0.18 mm, and the manufacturer's own guidance is that 480 performs best in thin bond gaps around 0.05 mm. It's designed for close-fitting parts, not loose or uneven joints. Wider gaps need a gap-filling adhesive such as an epoxy rather than an instant adhesive.
Does Loctite 480 resist chemicals, oil or fuel?
Reasonably well, with some variation by chemical. After 1,000 hours of continuous exposure at 22–40°C, published data on steel shows around 85% strength retained against motor oil, 70% against gasoline, 80% against ethanol, 75% against isopropanol, and 85% against Freon TA. Sustained high humidity (95% RH at 40°C) is harsher, retaining around 65% on steel — though the same test on polycarbonate retains 100%. Build this de-rating into the design for any joint that sees sustained chemical exposure.
Does Loctite 480 need primer or activator?
Not for its core substrates of metals, plastics and rubbers under normal conditions. An accelerator can be used if cure speed is too slow because of a larger bond gap, but Henkel's own guidance notes this can reduce the ultimate strength of the bond — worth testing before relying on it for a load-bearing joint. AIMS stocks Loctite 7452 Tak Pak Accelerator for this purpose.
Is Loctite 480 stronger than Loctite 401?
Not on raw shear strength — 401 and 480 are broadly comparable on steel (401 rated around 14 N/mm², 480 published at 22–30 N/mm², so 480 actually tests higher on steel specifically). Where 401 wins is rigidity and surface tolerance on a wider range of static substrates; where 480 wins is flexibility, peel resistance and impact tolerance. "Stronger" depends on whether the joint is static or dynamically loaded.
Why does Loctite 480 cure black?
The black colour comes from the rubber-toughening agents added to the formulation to give the cured bond flexibility and impact resistance. It's a direct trade-off — the same additives that make 480 tougher than a standard cyanoacrylate are what give it its colour, so a clear, invisible bond line isn't an option with this grade.
How should Loctite 480 be stored?
Store between 2°C and 8°C — storage outside this range can adversely affect the product's properties. Keep it in its original unopened container in a dry location, and don't return removed product to the container once it's been dispensed. Best application results come at 40–60% relative humidity.
Where can I buy Loctite 480 in Australia?
AIMS Industrial stocks Loctite 480 Prism Instant Black Adhesive with fast Australia-wide delivery.
People Also Ask — Loctite 480
Q: Can Loctite 480 be used outdoors?
Within its rated –40°C to +100°C operating range, yes, but like any cyanoacrylate it isn't a long-term UV-resistant or fully weatherproof adhesive on its own — for permanent outdoor structural bonding, check the specific exposure conditions against the environmental resistance data above, or consider a purpose-built outdoor adhesive.
Q: Does Loctite 480 work on rubber to metal bonds?
Yes — this is one of its strongest use cases. The rubber-toughened formulation is specifically suited to mixed rubber-to-metal joints that see vibration or flex, where a rigid cyanoacrylate would be more likely to crack at the interface over time.
Q: What's the difference between Loctite 480 and epoxy?
480 fixtures in seconds to minutes with no mixing; epoxy typically takes longer to cure but offers gap-filling ability and often stronger peel resistance for structural, load-bearing joints. 480 is the faster option for close-fitting parts that need some flex tolerance; epoxy is the better choice for structural bonds, larger gaps, or where maximum peel strength is the priority.
