Need to fix acoustic foam to the inside of a loudspeaker cabinet. Would prefer a glue with a non aggressive solvent in case it attacks the plastics etc used in the drivers. Or just leave the thing open for some time so it evaporates?
I was wondering if PVA would be ok?
Might be a good application for something like copydex - somewhat rubbery and elastic, no aggressive solvents etc.
I was thinking maybe that.
Or solvent free clear UHU type glue
PVA is good. Foam has to be flat, virtually no gap filling properties. Has to be left pressed together until it sets, may take a couple of hours.

I suppose a solvent-free contact cement would be OK; but the old solvent Evostick, etc. is a definite no-no; the vapour will rot cone suspensions.-hard won experience :( If the foam is for damping air vibration then stapling the foam to the wood will work. If you are trying to reduce the vibration of the wood panels then you do need to bond the foam to the wood
Copydex.... It was virtually made for this job :)
It's more normal to use bitumen or whatever panels to dampen vibrations to the wood. The foam is to reduce reflected sound within the cabinet. And stapling it would crush it, and reduce its effectiveness?
I'm thinking hot melt is probably as good as anything as the foam is largely self supporting anyway.
