Two new highly flexible instant adhesives are now available: Loctite®4902™ and Loctite 4903™, which reportedly offer elongations up to 155% and provide high-strength bonds in seconds. Both cyanoacrylate adhesives reportedly bond reliably to plastics, rubbers, metals and other substrates, and offer ISO 10993 biocompatibility for use on disposable medical devices.

These one-part, low-viscosity instant adhesives flow easily onto any substrate and typically fixture to handling strength in five seconds or less. 4902 is the more flexible of the two, with an elongation of 155% and a modulus of 57,900 psi. 4903 offers 85% elongation and a modulus of 78,100 psi. In comparison, conventional cyanoacrylates offer limited elongations of less than 2% and moduli of greater than 200,000 psi.

Both adhesives are designed for use on close-fitting, flexible parts and can easily bond dissimilar substrates from plastics to elastomers.
