<p>This prompts me to ask a question: I've never used Paraloid B-72
before, but a colleague strongly suggested that we switch to using
it as an adhesive for point-mounting insect specimens, and that it
is well-known to the general museum community, even if not
well-known among entomologists.</p>
<p>The little bit of research I did online suggests that it comes in
different forms, and is used in different ways, which makes it
somewhat unclear how best to approach it for our needs. If being
used as an adhesive, is it preferred to buy the solid form and
dissolve small quantities in ethanol? If so, does the
concentration of the ethanol matter? We have 95% ethanol we use as
a preservative, it would certainly simplify things if we could use
that without having to dilute it.</p>
<p>Recommendations for suppliers might also be helpful, given how
many sources seem to offer it for sale. We'd prefer to work with a
vendor with a positive reputation and fair pricing.</p>
<p>Thanks in advance,<br>
