Hi
Does anyone know what are the shear strengths of the various
off-the-shelve adhesive for plexiglas? Are there any online
documentation somewhere?

Thanks

Isn't it usually fused with a solvent, like MEK?

I have heard that the bond can be stronger than the plastic itself. Just
want to verify if this is true.

As usual, it depends. I did a medical device whose PMMA raw stock in
two different colors was adhered by a 50-micron thick line of 10%
polymer dissolved in monomer plus initiator, then cured. Any
destructive testing sufficient to crack the plastic never did it along
the bond line. As the final part was less than a millimeter thick,
that's pretty good. Whether it was a wonderfully good join or just
fractionally less brittle than its surroundings was not determined.

Solvent welding largely depends on the skill of the operator. Glues
depend on the glue and the skill.
