Dear Christian,
The adhesive OP29 you are using cures by UV-light and visible light. The
wavelenght of your UV source must match with the needed wavelength of your
adhesive. For this system you can also use a conventional spotlight. You also
have to check if your glass-type transmits enough (UV) light (filter
characteristic).
If you have to pre-adjust your system there is no need to cure the adhesive
complete. You can also use your UV-adhesive, there is no need for an additional
glue. Pre-cure your system, at the edges, so there is no movement. Then post-
cure your system beyond your bonder.
Otherwise look for some fast curing UV-adhesives such as products from DELO.
Best regards Matthias
