Glueing Rubbercords


#1

Hello there,

This is my second posting this day.

Yesterday I was trying to glue some bajonetclasps to rubbercord, but
I failed!!! Every time I stopped the cord into the tubes of the
clasps, the cords popped out of the tube. I am using Uhu 2
components, the blue glue. Then I tried wih an ordinary
one-second-glue and the same thing happened. The cord fits good in
the tube.

What did I do wrong?

Normally I buy them ready made. Thougt I could make them myself. I
feel rather stupid.

greetings,

You can drill a tiny hole in the end of the tube to relieve the
pressure. What I do is drill all the way through both tube and
cord, insert a piece of wire and peen over the ends. It’s a little
more work, but I don’t have to worry about the cord coming out!

I use two part epoxy. Not the 5 minute stuff, the stronger
version! Let it dry very well and you should be good to go!

There is a website for everything, it seems. This is the address
for one called This to That, where you ask what type of glue to use
to glue this to that.

Marlein–

Is it possible that the cord fits so tightly that, especially with
the added layer of glue, the air in the tube does not have any way to
escape as you insert the cord; and therefore, the compressed air pops
it back out?

I generally use superglue to glue the cords. I generally prefer
epoxies with a long cure time- 8-24 hours, but my local hardware
store uses superglue to make O-rings to order. So I switched,it
works better than epoxy-quicker, neater, but nothing works that well
on rubber. They all give way with time.

Elaine,

Thanks for the glue site info. Checked out the FAQ. Gluing crayfish
is a hoot. Check out Jeff de Boer. Amazing.

Hi:

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.

Hi Gail:

I’ve not used rubber very much, but was pleased with the Tenax+Plus
for the short trial I gave it - two weeks of steady wearing, pulling,
tugging, wetting, bending, etc. and it’s still very tight…

But, you mention in your posting that all adhesives eventually fail
with rubber. If you have used rubber for a long time, how long would
you say it takes before the adhesive fails? Several years or longer?

I plan to use 4 mm rubber cord for a single bead pendant - not heavy.
I love the feel of the rubber and love the contemporary look. Would
appreciate your input if you used lots of rubber in your work.
Thanks.

Rio Grande sells a rubber cord that is riveted. not glued.

I don’t know whether to be happy or sad to be an expert is this
field, but, here goes. When it comes to rubber cords and glue-
years isn’t appropriate. If an article is worn 1-3 times a week, in
a matter of months (6-9) you’ll notice the rubber is getting stiff
(I don’t know if this is a reaction to lotions, soap, etc.) it will
break if the glue doesn’t fail first. When this trend first
appeared, I got my replacement rubber at the local Do It, I was a
hero, none of our suppliers had it. That has since changed, and I
would recommend fire mountain gems for replacement rubber. But you
need to inform your customers that this is a maintenence concern. If
it’s a favorite piece, it won’t last 1 year. Glue aside, the rubber
will break after prolonged contact with the skin. (I will say I
don’t know if this applies to male jewelry, all my experience has
been with female oriented jewelry- necklaces in particular-
bracelets are not as badly affected)

message combined

I just reread your question and realized I didn’t answer it. My
preferred glue is Tenax +. Also Tenax 7R is the best stuff around
I’ve used for plastic.

Hello all you people,

Thank you for your respons to my question on glueing findings on
rubber cords. I was relieved knowing I’m not the only one
struggeling with glue.
