LOCTITE 480 Rubber-Toughened Instant Adhesive is a black, low-viscosity cyanoacrylate developed for fast, high-strength bonding of close-fitting metal, rubber, and plastic components. Its rubber-toughened formulation improves flexibility and resistance to peel, impact, and vibration compared with conventional rigid instant adhesives. The one-component material requires no mixing and cures rapidly through atmospheric moisture, helping manufacturers shorten assembly time while producing durable, professional-looking black bond lines.

LOCTITE 480 Rubber-Toughened Instant Adhesive Benefits

LOCTITE 480 Rubber-Toughened Instant Adhesive combines rapid fixture speed with enhanced mechanical toughness for demanding industrial assemblies. Henkel lists a typical fixture time of approximately 90 seconds on steel, allowing bonded parts to move to the next production stage with limited waiting. Its low viscosity, typically around 200 mPa·s, supports controlled wetting of narrow joints and accurately matched components.

The black color offers useful visual contrast during dispensing and can help conceal the bond line in dark rubber, plastic, and metal assemblies. Rubber toughening helps absorb and distribute stress generated by shock, vibration, movement, or differential thermal expansion. This makes the adhesive suitable for parts that may experience repeated handling or dynamic service conditions.

Applications for LOCTITE 480 Rubber-Toughened Instant Adhesive

Typical applications include bonding rubber seals to metal housings, attaching elastomeric components, assembling automotive trim, securing electronic parts, bonding small mechanical components, and joining close-fitting plastic or metal parts. It can also support maintenance repairs where fast handling strength and improved impact resistance are required.

The adhesive is suitable for many metals, elastomers, and plastics, but production testing remains essential because substrate formulations, surface treatments, additives, coatings, and molded release agents can affect adhesion. For difficult-to-bond low-surface-energy plastics, users should evaluate an appropriate LOCTITE primer and confirm performance on the actual material before approval.

LOCTITE 480 Rubber-Toughened Instant Adhesive Technical Properties

LOCTITE 480 is supplied as a black, one-part ethyl cyanoacrylate liquid. Henkel publishes a gap-fill capability of up to approximately 0.18 mm and a typical shear strength of about 26 N/mm² on grit-blasted mild steel under specified laboratory conditions. The recommended operating temperature range is approximately -40°C to 100°C.

These figures are typical reference values rather than guaranteed purchase specifications. Actual fixture time, cure rate, and final strength depend on joint gap, surface condition, material type, humidity, temperature, adhesive quantity, and bond geometry. Very dry conditions or large gaps may slow curing, while higher humidity usually accelerates fixture development.

How to Apply LOCTITE 480 Rubber-Toughened Instant Adhesive

Ensure all bonding surfaces are clean, dry, accurately fitted, and free from grease, dust, oxidation, release agents, and loose contamination. Apply a small quantity to one surface only. Assemble the parts immediately and hold them in position until sufficient fixture strength develops. Because cyanoacrylates work best in thin bond lines, avoid excessive adhesive and maintain close contact between the joined components.

Allow the assembly to develop full strength before applying heavy service loads. Wipe dispensing tips clean after use and close the container securely to limit moisture exposure. For accelerated curing of exposed adhesive, porous surfaces, or larger gaps, evaluate a compatible LOCTITE activator. Always review the current Technical Data Sheet and Safety Data Sheet before storage, handling, or production use.

Why Buy LOCTITE 480 Rubber-Toughened Instant Adhesive?

LOCTITE 480 Rubber-Toughened Instant Adhesive provides manufacturers with fast curing, simple one-part processing, strong close-fitting adhesion, and improved resistance to peel, impact, and vibration. Its black appearance and toughened performance make it especially practical for automotive components, rubber-to-metal assemblies, electronics, industrial equipment, and precision repair tasks.

Choose this product when a standard brittle instant adhesive may not provide enough toughness for a dynamically loaded joint. Review the official Henkel LOCTITE 480 product information before qualification, and explore our industrial instant adhesives for additional low-viscosity, gel, flexible, and high-temperature bonding solutions.
