Luckily in the package with the epoxy that I got, they sent me a lot of info and a catalogue showing all their epoxy products. They have some amazing epoxies ! Ceramic, machine-able epoxy, and the perfect epoxy for what I need, which is: potting for my electrical penetrators. This stuff (Duralco 4461 IP) is really great because it's very pourable and it has a heat tolerance of 500 F , that means I can safely solder my #4 stranded copper wire within a close proximity to the potted copper rods ! It's also ideal for electrical resistance. And low shrinkage . </div><div> </div><div>Here's a link to the 4461 IP :</div><div> </div><div><a href="http://www.cotronics.com/vo/cotr/ea_electricalresistant.htm" target="_blank" rel="nofollow" shape="rect">http://www.cotronics.com/vo/cotr/ea_electricalresistant.htm</a></div><div> </div><div>Brian</div><div> </div></div></div></blockquote></div><blockquote><div><span>_______________________________________________</span><br clear="none"><span>Personal_Submersibles mailing list</span><br clear="none"><span><a href="mailto:Personal_Submersibles@psubs.org" target="_blank" rel="nofollow" shape="rect" ymailto="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a></span><br clear="none"><span><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank" rel="nofollow" shape="rect">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a></span><br clear="none"></div></blockquote>_______________________________________________
