[Nhcoll-l] Paraloid B-72 applicators?

[Fabian Neisskenwirth]

Dear Nate,

I know its a bit of a late response.
Have you tried different solvents than acetone (pretty aggressive and 
super volatile). Paraloid B72 can be dissolved in ethanol as well. You 
can use a wide variety of solvents actually, depending on what you want 
to work on of course. A magnetic stirrer will be useful, since some 
solvents takes a wile to dissolve the pellets. For many of the purposes 
I use it, my solvent of choice is ethyl acetate.

Hope this gives you a wider view on the use of the resin.

all the best from Germany,
