Loctite highly flexible adhesives prove speed and strength can co-exist

In the past, users typically had to choose between an adhesive that offered fast fixture speed, or one that offered high strength. It has long been a trade-off. But today it doesn’t have to be. Henkel has developed two instant adhesives — Loctite 4902 and Loctite 4903 — that offer high flexibility and fast fixture speed while maintaining high strength on a majority of substrates.

Flexible adhesives

Henkel’s Loctite 4902 and 4903 are the first cyanoacrylate adhesives to offer elongations up to 155 per cent, and at the same time fixture in seconds, bonding to plastics, rubbers, metals and more.

These adhesives are ideal for applications where there are bond lines in the assembly that are highly flexing, as well as those that require sealing capability, like catheter assembly, tube-connector bonding, and devices undergoing bending and flexing, for example.

Loctite 4903 enables the use of dissimilar and opaque substrates while improving device performance, and offers significant performance enhancements compared to standard cyanoacrylates, including strength in flexing bond lines and resistance to leaks with excellent sealing capability.

Another bonus: both Loctite 4902 and 4903 have ISO 10993 certification for use in the medical device industry for the assembly of disposable medical devices.

A trusted brand

Henkel’s Loctite brand is the trusted choice for engineered, high-performance adhesive, sealant and coating solutions. The Loctite portfolio is designed to enable customer innovation, increase reliability and improve manufacturing operations in the most demanding industry applications.
