The new Born2Bond™ moisture-resistant adhesive 07 November 2022

Intertronics has announced Bond2Bond™ Aquafast, a new single-part, low odour, ‘instant’ adhesive suited for a variety of industries and environments with high humidity.

Aquafast is a low odour, low bloom, medium viscosity cyanoacrylate adhesive (CA) that offers good adhesion to a variety of materials. The new adhesive can withstand immersion in water after bonding.

Once cured, Aquafast forms strong bonds with metals, plastics and rubbers and is moisture and water resistant. The low water absorption rate of 0.8% over 24 hours allows bonds to maintain their strength when submerged in water, most solvents and oils. It is therefore suitable for applications including electronics and appliances, outdoor lighting, power tools as well as interior and exterior automotive aftermarket applications.

Born2Bond™ Aquafast has a high moisture and humidity resistance, showing small reductions in adhesion strength after 1,000 hours in environments with high relative humidity. The products hot strength has also been tested, yielding high adhesion performance in environments up to 120°C.

The adhesive has a fixture time of 15 seconds and is translucent when cured. Furthermore, it has a service temperature of between -40 and 120°C, which is higher than a typical CA’s recommended maximum operating temperature of 80˚C. “It’s generally thought that cyanoacrylate adhesives have poor moisture, temperature and humidity resistance. “These historic trade-offs have limited the usage of cyanoacrylates in applications where high temperatures, humidity and/or moisture are present,” said Ben Swanson, chief commercial officer of Intertronics.

“The Born2Bond™ range means that manufacturers using cyanoacrylates will no longer have to compromise. Aquafast will greatly broaden the potential uses of cyanoacrylates into applications where water or humidity resistance may have previously hindered their use, meaning more manufacturers can benefit from the rapid curing and strong bonding CAs offer,” adds Swanson.
