Intertronics now offers Bond2Bond Aquafast, a new single-part, 'instant' adhesive ideal for environments with high humidity. The adhesive is a low odour, low bloom, medium-viscosity cyanoacrylate (CA) adhesive that provides outstanding adhesion to various materials. Its key benefits include the capability to withstand immersion in water after bonding, and its excellent service temperature of up to 120C.
Once cured, it forms strong bonds with metals (including aluminium), rubbers, and plastics, and is moisture and water-resistant. The very low water absorption rate of 0.8% over 24 hours enables bonds to sustain their strength when submerged in water, most solvents, and oils. It is, therefore, ideal for applications including electronics and appliances, power tools, outdoor lighting, and interior and exterior automotive aftermarket applications.
The adhesive offers a fixture time of 15 seconds, is low blooming, and is translucent when cured, enabling manufacturers to profit from productivity advantages in applications where visual aesthetics are crucial. Moreover, it has a service temperature of between -40C and 120C, much higher than a typical CA’s recommended maximum operating temperature of 80C.
“It’s generally thought that cyanoacrylate adhesives have poor moisture, temperature, and humidity resistance,” said Ben Swanson, chief commercial officer of Intertronics. “These historic trade-offs have limited the usage of cyanoacrylates in applications where high temperatures, humidity, and/or moisture are present.
“The Born2Bond range means that manufacturers using cyanoacrylates will no longer have to compromise,” added Swanson. “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.”
