<DIV>Brian, this is not syntactic foam. It's made for marine service but not for deep submergence. It is really for surface buoyancy. I would not use this if you are relying on it for buoyancy at depth. It is the macro-spheres and microspheres in syntactic foam that prevent it compression at depth. I don't think this foam has either.</DIV><DIV><BR></DIV><DIV>Best Regards</DIV><DIV><BR></DIV><DIV>Cliff</DIV><DIV><BR></DIV><DIV><BR></DIV>

<DIV>Brian, I have been tied up and have not had a chance to follow this thread but I wanted to make sure you understand that unless this pour-able 2 part foam has a filler like 3-M's glass micro-spheres or some kind of incompressible macrosphere, then while the foam may appear rigid, it would compress when subjected to deep water and thus your buoyancy would be reduced. I don't think this is a replacement for syntactic foam if that is what you are doing. Can you send a link to the foam you are using?</DIV><DIV><BR></DIV><DIV>Best Regards </DIV><DIV><BR></DIV>

This pouring of the foam is not going to be as straight forward as I thought, The barrier to contain the foam is working out good, I'm just using wood and thin 1/8" luan , then I'm covering that with 4 mil flexible plastic ( heavy garbage type bag) so the foam won't stick to it. But I'm worried that any little gaps I have and the liquid foam might run out the bottom of those areas before it starts foaming, so I'm cramming big blankets ( cheap moving blankets from harbor freight) in tight to contain any foam. That way I can get the cavity that I'm trying to fill completely maxed out.
