Henkel Develops Loctite 3090, a Two-component Instant Adhesive for Gap Filling

Published on 2016-09-19. Author : SpecialChem

Düsseldorf, Germany -- Mind the Gap! Anyone who has traveled on the London Underground will be familiar with this safety notice. But “minding the gap” was also something that people had to do when using instant adhesives. With Loctite 3090, Henkel has developed the first gap-filling instant adhesive, thus considerably expanding the range of uses.

Instant adhesives can help to get quick results in many industrial manufacturing applications. They can be used to bond almost any kind of material, reliably and within seconds. Moreover, for maintenance and repair jobs, they often provide an economical alternative to expensive repairs or replacement parts.

Benefits over Traditional cyanoacrylate-based products


The conventional cyanoacrylate-based products generally have low viscosity and no gapfilling properties; they can only be used to bond close-fitting parts. This was a drawback that severely restricted the range of uses of these popular adhesives.

With Loctite 3090 from Henkel, a two-component instant adhesive is available that not only offers the same high bond strength and fast cure, but can also fill gaps. Henkel has thus vastly broadened the application range of instant adhesives, offering an unmatched capability to fill gaps up to 5 mm wide. Loctite 3090 is suitable for almost all materials, including metals, most plastics, rubber and ceramics. Even porous substrates such as wood, paper and cork can be reliably bonded with it.

Properties of Loctite 3090


  • It is a high-viscosity gel, which allows easier application to vertical surfaces – without dripping.
  • The convenient 2-chamber syringe packaging enabling precise and clean application
  • Loctite 3090 does not depend on the moisture in the air to cure, but has an additional activator

The two components are dispensed into an integrated static mixer, which ensures that curing is triggered within the defined timeframe, regardless of moisture or temperature, and that the components are always mixed in the right ratio. The adhesive has a working time of 90 to 150 seconds after application. The bond is then strong enough for use or downstream processing of the joined parts.
