I have always counted on JB Weld (Epoxy) for super strong bonds but lately I have had magnets glued to ABS and they come loose from the plastic side but not the magnet side (can't get it off the magnets so it's strong). It peels cleanly off the ABS plastic leaving nothing on the ABS at all and leaving a perfect imprint of the print texture in the JB Weld. So, what is a good very strong and long lasting (years at minimum) for ABS to metal?

The_Digital_Dentist Mostly this is for gluing magnets to plastic for use in my home and here in Southern CA indoors is normally 55f-80f so nothing major.]]> tmorris9 General Fri, 08 Dec 2017 22:51:32 -0500 https://reprap.org/forum/read.php?1,799481,799656#msg-799656 https://reprap.org/forum/read.php?1,799481,799656#msg-799656 the_digital_dentist General Wed, 06 Dec 2017 07:29:49 -0500 https://reprap.org/forum/read.php?1,799481,799624#msg-799624 https://reprap.org/forum/read.php?1,799481,799624#msg-799624 LoboCNC General Wed, 06 Dec 2017 01:18:55 -0500 https://reprap.org/forum/read.php?1,799481,799488#msg-799488 https://reprap.org/forum/read.php?1,799481,799488#msg-799488 www.loctiteproducts.com]
It may be that ABS gets a fairly impervious surface from the hot end and giving it a brush over with acetone, MKS or a mixture of the two may work as may roughening the surface to be glued. Variations of the added ingredients in different ABS filaments may mean that what will work for one won't work for all though.
