Nearly on topic, attaching Buna-N rubber to polyurethane
 

I have some 95A polyurethane grippers that are not holding on to the part we are attaching
fasteners to reliably. I want to take some .125" thick 60A (shore) Buna-N rubber sheet
and glue it to the grippers. Currently I'm thinking of something like Gorilla Glue but
I'm way open to suggestions. Fast cure time and not being something that gets the msds
readers upset is a plus.

Shoe Goo is the stuff to use for something like this

I would try 3M spray adhesive. It is contact cement in a fairly
easy to use form. Spray both surfaces for maximum hold.

"3M spray adhesive" covers a lot of territory. Did you have a
particular one in mind? Note that there's usually a two digit number on
the label, for example "3M Super 77", where the number identifies the
composition.

applications that I use.

My local suppliers only handle the 3M 77, so I never bothered to
think there were alternatives. I would point out that even at the
3M site, the standard answer for spray adhesive is the 77:
http://solutions.3m.com/wps/portal/3...3m.com/Super77

I did wander around though and found 99. I will need to get some
of this one to try:
http://www.shop3m.com/62494249709.ht...Spray-Adhesive
but at $21/can, I will use sparingly.

It's useful to know the different ones and what they do--I've got a
couple of cans (I forget the numbers and don't have them ready to hand)
that are roughly equivalent in adhesion to the adhesive on Scotch Tape
and on Postit notes respectively--both nice when I want to stick
something down and get it loose again, depending on how firmly I want it
stuck.

On the other extreme, back in the early '70s we used a hot patching
kit for tires. It involved spreading on the cement and burning off its
solvent. The patch was applied while the tire was still hot & soft.

Pre-mid 1975 until I left Indiana for the Marines, I patched a lot of tires using the
burning cement method. The guy that ran the gas station liked a dual strategy of plug and
patch for tubeless tires. The inside patch got the hot treatment.

I remember breaking down a tire for cop at that station. Said it went flat suddenly. Well
when I got it off the rim, I saw the little rubber balls that roll around except there was
one that had different dynamics which caught my eye. We figure it was a .22 mag rf. I
shot a few scrap tires with a .22LR and those tend to bounce off. ( I'll add bounce back
at you so don't do it)

Anyway, when I handed him the bullet, he got a bit quiet for a bit. Someone may have
tried to kill him. The tire was ruined. Steel belt.

Contact cement, the stuff that will kill you works best.


I'm going to try contact cement first. I picked up a can at a local hardware store today.
It has kidney failure warnings so it has to be good ;)

Before I posted I thought of:

3M #2001 Yellow death.

(not a current partnumber but it stuck to everything and I'm out of it after 30 years,
that stuff was awesome. I *think* the current Description and PN is Super Weatherstrip
and Gasket Adhesive, 8001, Yellow, 5 oz Tube)

I guess I'll find out Monday.

I misunderstood -- I thought you were replacing the urethane with
buna. Urethane is tough to glue. RTV silicone sticks to some urethanes
pretty well, and I imagine it would stick to buna.

In that vein, I've used RTV beads applied to a urethane feed belt to
increase grip. Perhaps that would work on your grippers.

If contact cement doesn't work, I'll try RTV.
