Ask
Dr. Dan
Can you glue PETG?
Some
fabricators say no, others say yes. The one's who say yes have learned
that you can't just take what you know about gluing acrylic and
apply it to PETG and expect it to work. It's not just the solvent
you're using but your technique at applying the solvent that matters
most. Weldon 4, Schwartz Chemical's SC-94, and Rez-N-Bond will all
work acceptably as long as you make sure to use a generous amount
of it, have clean, machined, smooth edges, and clamp your parts
with light but firm pressure for a sufficient amount of time before
moving on to additional steps.
Also,
other adhesives may be used but will have longer curing times. Most
people accustomed to acrylic fabrication will reject adhesives outright
because of the length of time for curing, so for PETG they will
not make any new exceptions. For those people interested in learning
more about gluing PETG, I recommend cruising Sheffield's web site
on Vivak, http://www.sheffieldplasticsinc.com/sheffield/techtips/vivakfab/vbond.htm
