Different wavelength to cure UV adhesive

In uv adhesive field, Loctite, Delo and Dymax are main supplier. Most these brand uv glue could be cured by uv led curing system. Alos these three uv glue supplier supply uv curing equipment for their own uv adhesive, but it is very experience.

Could we choose the other brand uv curing system to cure these uv glue? Answer is "yes!" You could find "secret" about uv wavelength in uv adhesive technology data sheet. Here are Some normal uv adhesive technology for your reference.

1.Loctite 3301

Here is the TDS from loctite website

HEIGHT-LED

Clearly it need 365nm uv led curing system. Actually 365nm and 395nm led uv light both ok, according to our test. 365nm is better.

2.DELO-PHOTOBOND® 4494

HEIGHT-LED

It is cured by both 365nm and 400nm.

3. Dymax

3025 had a higher mean maximum load when cured at 405 nm than it did with the broad-spectrum
control.
3099 had a higher mean maximum load when cured at 365 nm than with the control.
1403-M had similar mechanical properties at all three LED wavelengths and the control.
1201-M-SC had a higher mean maximum load when cured with LED than with broad spectrum.
1180-M had the best cured mechanical properties when cured with broad spectrum.
431 had the best cured mechanical properties when cured with broad spectrum but was very close to the
performance at 385 nm.
6-630-T had the best cured mechanical properties at 365 nm and 385 nm.
Of the four conformal coatings tested, only 984-LVUF cured tack free at 365 nm and 385 nm and with
slight tack at 405 nm.
So different wave maybe different curing result.
