Collection: Henkel

Loctite is the industrial adhesives brand of the Henkel group. Dagobert Industrie stocks twelve of its references, focused on the technologies where it is the workshop benchmark: cyanoacrylates and anaerobics.

The 12 references in the catalogue

• Cyanoacrylates: Loctite 401, 402, 406, 409, 454, 480, 495, 496, 4902, and 3090 two-component high gap filling. See our cyanoacrylate adhesives.
• Anaerobic: Loctite 272 high strength threadlocker. See our anaerobic adhesives.
• UV: Loctite AA3926 one-component adhesive. See our UV adhesives.

Reading a Loctite reference

In the cyanoacrylate family, numbers follow a logic of viscosity and intended use, and a few landmarks are enough in practice.

401 and 406 are thin and versatile, 406 being geared towards elastomers and plastics. High numbers such as 480 designate toughened formulations, more resistant to impact and peel. 454 is a gel, which does not run and allows vertical work.

3090 stands apart: two-component, it fills gaps far larger than a conventional cyanoacrylate can bridge.

Choose viscosity before the reference

A thin adhesive penetrates by capillary action into an assembly already in place, but it requires well fitted parts: beyond a few hundredths of a gap, the joint is hollow.

A gel adhesive fills a few tenths and holds vertically, at the cost of slower curing.

Threadlocker, and the question of disassembly

A threadlocker is chosen on the expected breakaway force, not on its maximum strength. A high strength threadlocker like 272 often requires heat to loosen. On an assembly meant to be taken apart for maintenance, it is a poor choice, even if the stated hold looks better.
