Port adhesive ? ABS to MDF

LexD · #1 10-06-2011, 11:26 AM

I am currently restoring an older Trace Elliot 1528 I purchased from a fellow TB'er.

This cab has 2 15's and 4 ports made of ABS plastic - the black pipe.

A few of the ports seemed to have wiggled their way free from the adhesive used on the backside of the baffle made of MDF.

I've removed all the old glue (looked like silicone caulk?)

What is a good adhesive to use to put the ports back in their place ?

Eclectic Products E-6000 (very similar to shoe repair glue). Dries clear and bonds to nearly anything. Available at most building supply stores.

Head on over to the Home Despot and grab a tube of goop.
The general purpose type.
It's in the paint section.
Smear it inside the hole and on the end of the tube.
Twist it in, ( hopefully it is a tight fit? )
Have a beer while it dries.

Cheers!!!!

Does PL Premium stick to plastic? That stuff is cement when it dries. I used GOOP years and years back to glue the PVC pipe ports inside car stereo sub boxes. 150+ degrees in a trunk during summer down here and never had a port come loose.

That said, if PL will work, it is the superior adhesive.

Unfortunately, it won't. Been down that path already.

PL Premium Technical Data Sheet Limitations

Not recommended for use on ABS or polystyrene tub surrounds

Looks like the E-6000 or GOOP, will be ideal.

Whoops, guess there's your and my answer then!

GOOP is very good for this application, as I stated above. Just "goop it on" . If you can get at the inside of the box with the port installed, run an additional thick bead around it on the inside of the box. Good luck.

Contact cement is another option. You apply to both sides, wait for it to partly dry and become tacky, then BLAMMO!! instant bondification.

Bondification. That is what you're looking for. Strong, steel-like Bondification. :thumbsup:

.
All I've ever used is plain old clear silicon on my ports.
I've never had one work loose yet.

Works for me!

Gorilla Glue, sticks to everything, stays flexible.

Update :
I went ahead and tried the GOOP (all-purpose). 1/2 tube spread around 4 4" ports. The bond is plenty strong enough. I tried to make a small height adjustment ~8 hours later to no avail. Cemented up good.

The end result was strong, but not very pretty. The Goop dried to clear, but against the black baffle it looked bad. Acetone is the suggested clean-up but as acetone is a no-no for ABS I ended up having a lot of excess glue that needed to be removed by hand and x-acto.

Just to make sure there was no air leaking around the ports I ended up going back over each joint with a thin bead of black silicone and made a fillet with a damp towel. Very happy with the results. Thanks all!
