adhesives are excellent for use on glass to glass or glass to metal applications.
They are very high strength so are suitable for load carrying joints such as
glass furniture and display cabinets. Flexible products are available for cases
where differential thermal expansion between parts occurs. Plastics, such as
acrylic and polycarbonate, would need to be checked for UV transmittance (as
quite often plastics are UV stabilised). Permabond technical staff can check
this and suggest or develop suitable products to meet your application requirements.
What are the benefits of UV-curable adhesives?
Single-part adhesive chemistry allows rapid preparation, application and cure.
UV-curable adhesives are capable of joining dissimilar materials, such as
acrylic to metal, with no compromise in bond strength.
Cure in seconds - which eliminates the need for costly jigs or ovens and accelerates
Permabond UV adhesives are solvent free and non flammable.
They exhibit superior bond strength which often exceeds that of substrate
The finished appearance is aesthetically pleasing.
Cures on demand to allow proper alignment of components before bonding.
Optically clear products.
How do Permabond UV-curable adhesives work?
Permabond UV-curables contain a photo-initiator which when exposed to Ultra
Violet or blue light radiation, triggers the acrylic adhesive to cure instantly.
To transmit the UV light requires at least one of the substrates to be clear.
For shadow areas, products with dual cure mechanisms are available.
How do you cure the product? Will it cure in normal daylight?
There are UV rays in normal daylight which can cause the adhesive to slowly
gel and cure although it won't achieve full strength, so you would need to use
a UV-lamp. Permabond can help you with this. Lamps are available in a variety
of luminosities from small inexpensive hobby lamps to larger high intensity
units. Permabond will hep you select the best type of lamp for your specific
How long do they take to cure?
We quote cure speeds for each of the products on thefollowing table. These
are rough guidelines as it is dependent on the intensity of the UV light, the
distance from light source and the transmittance through the substrate material.
