I think I found the product you reference.
Here's what the company states:
I see no mention of ingredients or a safety datasheet which would provide the information as to ingredients.
My conclusion (inferred from statements on the product page and confirmed with what I found on AK) is given that (a) acetone can be used to clean it up and (b) the description of strings when gluing (see below), that it is an copolymer adhesive using acrylic (aka superglue or cyanoacrylate), with some added vinyl or styrene groups, maybe some rubbery groups to make it flexible, or some combination of the the above. Such an adhesive dries stiff, and is not suitable for use as a surround sealant. As I keep saying, there is a difference between adhering the surround to the frame and cone, and sealing a
flexible surround which must remain flexible.
The product description then goes on to say:
Q: i need to reseal the cloth surrounds on ar3a woofer, do you have the correct product? Asked by: matt - 5/31/2016
A: Yes, please use our PVA edge sealer part # MI-3035FG.
This makes me distrust anything written about those products, as PVA is unsuitable for such purpose. But, most important, if this were a butylene-rubber based (and it clearly is not) product then it would be suitable for use as a surround sealant, instead of a suggestion to use PVA, which, again, is totally unsuitable. Again, the company does not suggest this for use as a sealant. That alone ought to make anyone think twice.
BTW: that tube glue was not favorably reviewed on AK:
I suggest reading through this entire thread:
Note that some of the sealants hardened over time, raising Fs. Never a good thing.
