transparent light curable adhesive

Dear Martin:

You cannot have it both ways. If it is light cured (before cure), it cannot be transparent to interact with light. Maybe there will be an infrared-activated transparent adhesive...

Superglue is clear...

Masterbond UV-15X-2 is worth a look

I have had good results with Loctite 352 structural UV adhesive. It requires a real UV source to cure, though. It doesn't perform very well with an ordinary "blacklight". Direct sunlight works fairly well, but is slow (depending on film thickness).

transparent doesn´t necessarily mean 100 % transmittance = no absorption

Dear Martin:

But it does mean something like 99% of all visible wavelengths, so 1% would still be inadequate unless the light intensity was high. So far the only "hits" have been UV cure, which is a completely different wavelength.

It can be if it's UV cured, some years ago I worked with UV cured adhesives to laminate layered eyeglass lenses. Crystal clear, but of course 100% UV blocking... which is what you want in glasses anyway. Check out Dymax, which is IIRC where we got it from.

UV is not >400nm, the requirement of the problem. So its IR cure, or its not transparent until it *is*cured (which might suffice).
