<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 clear="none"></div><div>Best Regards </div><div><br clear="none"></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. Waiting for an 80 + degree day . </font></font></div><div><font size="2"><font face="Arial, sans-serif"><br clear="none"></font></font></div><div><font size="2"><font face="Arial, sans-serif">Brian</font></font></div><div><font size="2"><font face="Arial, sans-serif"><br clear="none"></font></font></div><div><font size="2"><font face="Arial, sans-serif"><br clear="none"></font></font><br clear="none"><span style="font-family:Arial, sans-serif;font-size:10pt;">--- personal_submersibles@psubs.org wrote:</span><br clear="none"><br clear="none"><span style="font-family:Arial, sans-serif;font-size:10pt;">From: Brian Cox via Personal_Submersibles <personal_submersibles@psubs.org></span><br clear="none"><span style="font-family:Arial, sans-serif;font-size:10pt;">To: "Personal Submersibles General Discussion" <personal_submersibles@psubs.org></span><br clear="none"><span style="font-family:Arial, sans-serif;font-size:10pt;">Subject: Re: [PSUBS-MAILIST] Foam preperation</span><br clear="none"><span style="font-family:Arial, sans-serif;font-size:10pt;">Date: Mon, 24 Jun 2019 16:12:46 -0700</span><br clear="none"><br clear="none"><div><div style="font-family:Arial, sans-serif;font-size:10pt;"><font size="2">My first batch of foam cam today ! yay ! two five gallon pails, A and B, should be interesting !</font><div><font size="2"><br clear="none"></font></div><div><font size="2">Brian</font></div><div><font size="2"><br clear="none"></font></div><div><font size="2"><br clear="none"></font><br clear="none"><span style="font-size:10pt;">--- personal_submersibles@psubs.org wrote:</span><br clear="none"><br clear="none"><span style="font-size:10pt;">From: hank pronk via Personal_Submersibles <personal_submersibles@psubs.org></span><br clear="none"><span style="font-size:10pt;">To: Brian Cox via Personal_Submersibles <personal_submersibles@psubs.org></span><br clear="none"><span style="font-size:10pt;">Subject: Re: [PSUBS-MAILIST] Foam preperation</span><br clear="none"><span style="font-size:10pt;">Date: Fri, 21 Jun 2019 17:47:56 +0000 (UTC)</span><br clear="none"><br clear="none"><div style="font-size:13px;"><div></div>
