I recently tried TENAX+PLUS for glueing solid rubber cord to its
metal findings. I wore the cord every day for several weeks, tugging
on it when I thought about it. I wet it, pulled on it, bent it back
and forth, hooked and unhooked (I used a lobster clasp) and in
general gave it a rough time and so far it is still bonded tightly.
This was done strictly as a test before I use it on a finished piece.
The packaging says "Water clear bonding". "Tenax+ Plus is designed
to bond stones, ceramics, glass, porcelain, metals, wood, paper,
cloth, rubber, vinyl and some plastics. Too much adhesive prevents
bonding". It contains cyanoacrylate ester.
Now two weeks is not a conclusive test, but with the treatment I've
given it, I'm pretty convinced that it's solidly bonded to its
findings. As always, this is just my personal opinion, not a
spokesperson for or connected with Tenax+Plus.
