Foam borders repair

Tubesin · 28th March 2007, 01:27 PM

Hello, my both AN low frequency drivers' borders are damaged due to humidity. I found new border in foam, but, I don't know which kind of glue to use, some suggested white glue... I'm afraid the glue can damage the foam border, so, may I have your kind assistance on which kind of glue to use? Thank you.

Hi,

PVA wood glue is perfect for foam to a paper cone, but not a plastic cone.

Hi

I have used "evostick" which is a rubber solution with success in the past. Being a rubber solution it remains pliable when set.

Thank you. The AN driver's cone is paper and surround in foam. If wood glue is good for paper to foam, how about foam to aluminum basket of this driver? Can same glue workable?

Hi,

Rubber solution, i.e water based latex adhesive, (brand name here
"copydex"), is almost certainly the adhesive supplied with the kits.

Hi,
the glue from Speaker Bits (AUS) and from Speaker Place (US) is not rubber solution like Copydex.

It may be a re-formulated PVA, but is stickier and faster setting than PVA.
Speaker Place glue dries clear and shiny and hard which is reminiscent of cured PVA

Hi,

OK.
Then it sounds like waterproof (for external use) PVA wood glue,
this will be fine as long as there is no tendency / tension to lift.

Hi
The advantage of evostick is that it remains very pliable when set. It is not water based. I am not sure what the thinners is but it can be removed before setting by using cellulose thinners. It is best to be careful with it though as it is very sticky.

I have used it on foam surrounds and rubber surrounds with success.

You must be doing something wrong. Evostick has always (7 times) worked just great for me. The first time was over 10 years ago on a castle speaker and the speaker is still fine - I just checked it.
