dlaery Posted September 7, 2016 Report Share Posted September 7, 2016 Is there any kind of glue that works with this? I tried some gel CA to glue 2 pieces together and clamped for 2 hours and it didn't get dry. so I screwed it together. Now I need to attach a thin piece of silicone to the HDPE. I would like to try RTV hi temp silicone but I dont think it will work. has anyone had any luck glueing HDPE? Quote Link to comment Share on other sites More sharing options...

goolies Posted September 8, 2016 Report Share Posted September 8, 2016 Heated to the right temperature HDPE will bond to itself. Quote Link to comment Share on other sites More sharing options...
Chuck Young Posted September 10, 2016 Report Share Posted September 10, 2016 The melting point of HDPE is 358 deg F. Then you face the issue of how to get both sides to melt at the same time, and only where you want it to. Sounds like more trouble than it is worth.

JimP Posted September 13, 2016 Report Share Posted September 13, 2016 (edited) Here is a copy of a fabrication guide that I found for working with HDPE. There was some mention in this thread of adhesive usage, page 11 in this guide addresses that subject. https://dl.dropboxusercontent.com/u/1924904/HDPE-Fabrication-Guide_Rev-B_2013.01.pdf Edited September 13, 2016 by JimP Quote Link to comment Share on other sites More sharing options...
