That looks like hot melt adhesive, i.e. glue.

  • Does it matter if you use high temp or low temp glue? I'm guessing you'd want low temp for most applications? – K H Mar 27 '21 at 01:39
  • @KH, I read somewhere that high temperature hot melt glue can damage insulation. – Mihail H. Apr 01 '21 at 15:12
  • @mihail-haritonov thank you. I always see a variety of goos used for mechanical support or thermal protection or as I recently learned as mechanical protection and isolation for a bare die chip. I figure if I need one I'll probably go with hot glue or try to find a silicone that doesn't wreck electronics, but now at least I know Dad's industrial glue gun is probably a bad idea. – K H Apr 01 '21 at 22:34
  • @KH, in https://electronics.stackexchange.com/a/18533/144719 helpful answer author recommends neutral cure silicone rubber (Dow Corning 839, for example, if I understood correctly the comments on the answer) instead of hot melt glue. – Mihail H. Apr 01 '21 at 23:18
  • @mihail-haritonov thank you that's golden. – K H Apr 01 '21 at 23:24
