Mike - The information is great for those who have airplanes which last for many years. There are a lot of pilots who don't have to worry about old age problems of their airplanes. :-)<div><br></div><div>Ron Van Putte</div><div><br><div><div>On Sep 13, 2011, at 10:52 AM, Michael S.

This is all helpful, my concern is what I have witnessed over many years as the heat and fuel ruined the 5 min epoxy. Since it is electric, fuel is not an issue but there is plenty of concern about heat. I don’t know the deformation temp of the epoxy nor the exposure to normal environment so that is why I was asking. I am going with the 5 min and doing a thin coating of laminating to have a seal and redundancy. Sunlight will eventually ruin the epoxies but since it is inside the fuse, that is not an issue. <o:p></o:p></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Thanks<o:p></o:p></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Mike <o:p></o:p></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p><div><div style="border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in"><p class="MsoNormal"><b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif"">From:</span></b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif""> nsrca-discussion-bounces@lists.nsrca.org [<a href="mailto:nsrca-discussion-bounces@lists.nsrca.org">mailto:nsrca-discussion-bounces@lists.nsrca.org</a>] <b>On Behalf Of </b>Ted Sander<br><b>Sent:</b> Tuesday, September 13, 2011 6:54 AM<br><b>To:</b> 'General pattern discussion'<br><b>Subject:</b> Re: [NSRCA-discussion] 5 min expoxy<o:p></o:p></span></p></div></div><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I tend to use whatever the local shop carries – but do lean toward Z-poxy. The current Pres. Of our local club spent his career formulating adhesives, so I trust his opinions, and in his view all hobby marketed expoxies are far stronger and longer lasting than we ever need, so go with price. That said, longer curing is stronger than shorter curing (but once you are good enough, do you really need it stronger?) and using laminating is better than thinning with alcohol, acetone, or whatever if you need to coat an area…..(thinning does dramatically reduce strength).<o:p></o:p></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">If you are getting into whole plane fabrication with epoxies (glass/composite construction, etc.) then you need to do some more research for thin film strengths, viscosity, etc. , especially since weight becomes a big factor.
