Loctite 410 Black Toughened Instant Adhesive 20g
Available
Loctite 410 is a black, rubber-toughened ethyl cyanoacrylate instant adhesive. It is a one-part, high viscosity liquid that cures with atmospheric moisture and needs no mixing.
It has increased flexibility and peel strength, along with enhanced resistance to shock. It bonds metals, plastics and rubbers, and it suits thin bond gaps.
Where this product is used
- Bonding metals, plastics and rubbers
- Rubber (neoprene, nitrile) bonded to metal
- Bonding ABS, PVC, polycarbonate and phenolic plastics
- Joints where a rubber-toughened bond line with enhanced resistance to shock is wanted
Features
- Black liquid, it is a liquid, not a gel
- Rubber toughened, with increased flexibility and peel strength
- Enhanced resistance to shock
- High viscosity: 1,700 to 5,000 mPa·s
- One part, no mixing
- 22 N/mm² lap shear on grit-blasted steel (24 h at 22 °C, ISO 4587)
- Glass transition temperature of 120 °C

Choosing the right option
Loctite 410 is the black, high viscosity toughened grade. For a clear to straw-coloured toughened grade, see Loctite 435 Toughened Instant Adhesive 25ml; for a black grade, see Loctite 480 Black Toughened Instant Adhesive 20g.
For a general purpose grade without toughening, see Loctite 401 Instant Adhesive.

Using it
The product suits thin bond gaps (0.05mm). Increasing the bond gap decreases the rate of cure.
Fixture times are the time to 0.1 N/mm² shear at 22 °C and 50% RH, and vary widely by substrate: degreased steel takes 60 to 120 seconds, aluminium 10 to 30 seconds.
Full chemical and solvent resistance takes at least 24 hours.
Steel lap shear is at least 19.3 N/mm² when cured 24 h at 22 °C plus 24 h at 121 °C and tested at 22 °C.
Storage and handling
Store unopened, in a dry place, at 2 °C to 8 °C. Storage outside this range can affect the properties of the product.
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.
