I can’t believe, here in 2019 already, how hard it is to find any info or easy answers to bonding PETG.
Has anyone had success with bonding / gluing PETG parts to PETG and other materials? Any experience with the below Loctite products?
The ‘low-energy’ polyethylene part of PETG seems to be the big challenge for most adhesives.
Interested in PETG to PETG for general use, and PETG to carbon steel for grips on a hatchet.
Had a helpful conversation with a Loctite technical rep, and am considering these three products:
Loctite HY 4070 - a two part ‘hybrid’ cyanoacrylate/acrylic gel (mix of both the below chemistries)
Loctite AA 3035 - two part acrylic methacrylate adhesive gel system designed for bonding low energy plastics
(same root as above)/structural-adhesives/loctite_aa_3035.html
Loctite 480 - toughened (rubber added) ethyl cyanoacrylate with high shock resistance.
(same root as above)/product/instant-adhesives/loctite_480.html
Also interesting is the Loctite 4090…, a variant of the 4070.
These are all expected to work with low energy plastics, and a couple of them specifically reference as good for polyethylene.
Appreciate any suggestions for other products, too.
