How do Permabond cyanoacrylate adhesives work?

Permabond cyanoacrylate adhesives are one part adhesives that cure by reacting with minute traces of moisture on the surface of the material being bonded. They cure in seconds at ambient temperatures and have been formulated to bond flexible or rigid surfaces made from a wide range of plastics, rubbers or metals.
How do Permabond UV-curable adhesives work?
UV adhesives do not dissolve, melt or weaken the two component. They form strong chemical bonds between the two substrates and provide a high strength alternative to other joining methods. They can be used to replace solvent welding to help reduce stress cracking and to increase bond strength and performance. UV-curables are also a good alternative to ultrasonic welding as they are more able to cope with gaps or varying tolerances, this helps reduce reject rates.
Which sterilisation procedures will the 4C range withstand?
Ethylene oxide sterilisation
● Gamma irradiation
● UV-irradiation
● Not suitable for autoclave sterilisation.

Typical Applications:
● Catheter bonding
● Bonding components for breathing masks
● Tacking wires and bonding materials for electro-cardiogram pads
● Bonding connectors to tubes
● Disposable scalpals - bonding blade to handle
● Bonding sponge swabs to swab stick.
Typical Applications:
● Face mask bonding
● Needle bonding
● Bonding connectors
● Catheter bonding
● Blood collection reservoirs.
Benefits of cyanoacrylates
● Cure in seconds - ideal for high-speed production
● No need for curing equipment
● Form high-strength bonds - often exceeding that of the substrate material.
● Colourless and transparent for a clean, aesthetically pleasing finish.
● Can adhere to difficult-to-bond materials.
Benefits of UV-curables
● Cure in seconds - ideal for high-speed production lines
● Form high-strength bonds – often exceeding that of the substrate material.
● Colourless and transparent for a clean, aesthetically pleasing finish.
● Can adhere to difficult-to-bond materials.

Products pass USP Class VI and cytotoxicity testing.

UV-Fluorescence: The 4UV80 range products are UV-fluorescent for easy in-line QC inspection. These products can be supplied without UV fluorescence if desired.
Light Sensitivity: The 4UV80 range is highly reactive to allow cure through difficult plastics. Should a less-active product be required due to strong factory lighting, Permabond can produce light insensitive versions of the above products.
OTHER MEDICALLY APPROVED UVS
Permabond UV630 series UV-curables have cytotoxicity approval.
Other Permabond adhesives commonly used in medical device manufacture include acrylic adhesives, epoxy adhesives and anaerobic adhesives.
● Two part epoxy ET500 for glass to metal
● Anaerobic MH052 for metal connections in oxygen delivery devices
● Anaerobic A1042 for tamper proofing medical equipment case covers
● Structural Acrylic TA 440 A&B for sealing attachment points of equipment carts, gurneys and stretchers.
