GlennCauley Posted July 25, 2012 Share Posted July 25, 2012 When making some PE parts, it requires folding pieces to make the part thicker. So what you end up is essentially a "sandwich" of layers of PE... sometimes several layers thick. QUESTION: How do you seal the edges of these layers of folded PE so when you paint the part it looks like a solid part and not layers of metal? Quote Link to post Share on other sites
Bigasshammm Posted July 25, 2012 Share Posted July 25, 2012 Soldering iron most likely. I know lots of people use them to join pieces of pe together. Don't see why it wouldn't work in this case as well. Since I don't have or know how to use a soldering iron I'd probably put a small glob of gap filling ca glue either before the fold or afterwards and then sand smooth.

Triarius Posted July 25, 2012 Share Posted July 25, 2012 I just run a bead of CA along the seam. If you use a super thin CA, like Mercury Adhesives thin formulation (thinnest CA I've ever seen) it generally leaves a smooth seamless surface. Sometimes needs more than one application.

smithery Posted July 25, 2012 Share Posted July 25, 2012 I use plain old white glue. Dries clear, and doesn't leave a mess. One the PE sandwich is completed, I apply it with a toothpick to all of the exposed edges, and remove it with a Mk.I licked finger. Let dry, and you're good to go.

MaRiO FDZ Posted July 25, 2012 Share Posted July 25, 2012 a couple of drops of CA in the layers does the trick usually... HTH Take Care Quote Link to post Share on other sites

I have some "Weld Bond" at home... is that essentially the same thing? Quote Link to post Share on other sites
