I've ordered the Scotchcast 2131B resin from Digikey, and it looks like you can order the primer from them too. It's a bit expensive though (~$220 per can), and I'm not sure how much you'll need it... At Saildrone we just use the 2131B for potting cables, I don't think we use any primer, and it ends up being really tough stuff. But as Dan said, cleaning with acetone before potting would probably be good.<br></div><div>The 2131B is kind of annoying since it comes in pouches of 7.5oz, and you can't really save it after you've cut open the pouch. So it's best to line up all your casts and do them all at once if you have a few to do.<br></div>-justin<br></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Fri, Jan 17, 2025 at 7:02 AM Daniel Lance via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Sean ,<div>I did a quick Google search and found " 3M Scotchcast Electrical Primer 5136N" .
