Adhesive to hold Speaker crossover components

Started by amdx October 6, 2015
I'm replacing a couple of capacitors in speaker crossover.
The parts have a glue that holds them tight to the PCB, the glue is 
still a little bit rubbery after 33 years. (Pioneer HPM-700)
  What can I use that will do the same job, without solvent damage
to the electronic parts?

Sounds like RTV Silicone. That's what I use for heavier components subject to vibration. eg... http://uk.farnell.com/dow-corning/3145-90ml/rtv-silicone-clear-tube-90ml/dp/537007 Cheers -- Syd

A little hot melt?

Thanks Guys, A 10 minute search and a phone call to the wife, I just had to dig deeper into where I thought the hot glue was. Mikek

It is all over your synapses and holding your eyelids shut.

Expectations. I was looking for the orange power cord. It was in a bookcase behind other items, in a bag. I couldn't see the orange cord through the bag. In other words, it was my wife's fault! Mikek :-)

** Hot melt glue sometimes fails to adhere to particular plastics over the long term and components come loose. Seen this many times with large electros and crossover coils and caps on PCBs. Silastic is much better, but make sure you get a "neutral cure" type with no smell of acetic. ... Phil

Lexel Adhesive Caulk

read the fine print.
can use on polycarbonate as I did, so most anything it sticks to and 
remains slightly flexible.

I bought a gun-sized tuber for the bathtub, etc. but havenn't used it yet.
