Loctite 480 Black Toughened Instant Adhesive 20g
Available
Loctite 480 is a black, one-part, rubber-toughened ethyl cyanoacrylate. It is a low-viscosity liquid that cures with atmospheric moisture and needs no mixing.
It bonds metals, plastics and rubbers. Henkel gives 22 to 30 N/mm² lap shear on grit-blasted steel after 24 hours at 22 °C.
Where this product is used
- Bonding metals, plastics and rubbers
- Rubbers such as neoprene and nitrile, which fixture in under 20 s
- Plastics including ABS, PVC, polycarbonate and phenolic
- Steel, aluminium and zinc dichromate parts
- Joints where a black adhesive suits the parts

Selecting the right option
For another black toughened grade see Loctite 438 Black Toughened Instant Adhesive 25ml; for a clear toughened grade see Loctite 435 Toughened Instant Adhesive 25ml. Compare the fixture times in each Henkel data sheet against your materials.
Using it
Henkel gives the thin bond gap (0.05 mm) as where the product performs well. Larger gaps slow the cure, and an activator can speed the cure but may reduce final strength; see Loctite 7452 Cyanoacrylate Accelerator 20g.
Curing continues for at least 24 hours before full chemical and solvent resistance develops.
Do not return used product to the container.
Storage and handling
Store unopened and dry at 2 °C to 8 °C. Storage outside this range can adversely affect product properties.
Limits and safety
Not recommended for pure oxygen or oxygen-rich systems, or as a sealant for chlorine or other strong oxidising materials. Read the safety data sheet before use.
Frequently asked questions
How fast does Loctite 480 fixture?
At 22 °C and 50% RH it reaches 0.1 N/mm² in 60 to 120 seconds on degreased steel and in under 20 seconds on neoprene and nitrile rubber.
How strong is Loctite 480 on steel?
Lap shear is 22 to 30 N/mm² on grit-blasted steel after 24 hours at 22 °C (ISO 4587).
What is the heat resistance of Loctite 480?
Henkel gives a glass transition temperature of 150 °C and a hot-strength graph, but states no rated operating range. After 24 hours at 22 °C plus 48 hours at 120 °C, steel lap shear is 18.0 N/mm² or above.
What bond gap suits Loctite 480?
Henkel says it performs well in thin bond gaps (0.05 mm). Larger gaps slow the cure.
Does Loctite 480 have any approvals?
The current Henkel data sheet lists no approvals; contact AIMS if you need a certificate for a specific application.
How should Loctite 480 be stored?
Unopened and dry at 2 °C to 8 °C.
