[Nhcoll-l] Paraloid B-67 in naphtha....

[Cory Redman]

I have tried dissolving Paraloid B-67 in naphtha and mineral spirits that
were purchased from a local hardware store with no success.  The B-67 has
just turned into a large gooey mass at the bottom of the container and no
amount of agitation or time (going on 4+ weeks) seems to help.  What am I
doing wrong?

I am very familiar working/mixing Paraloid B-72 in acetone or ethanol, but
this is my first time using B-67 and yes, I need to use B-67 in naphtha for
the objects being numbered.

I would appreciate some help/tips/guidance.  I haven't been able to find
anything in the literature, but I probably am missing a key paper(s).
