A short questionnaire on polyvinyl acetate resins

As I reported here last month, Union Carbide is no longer
manufacturing PVAc resins (AYAA, AYAC, AYAF and AYAT).  I am
continuing to investigate possible replacement resins that would be
appropriate for use by the conservation community.  Possible
replacements include the Mowilith resins (20, 30, 40 and 50), McGean
B-15 and B-25 (formally Vinac B-15 and B-25), and the PVAc resins
currently supplied by TALAS (called AYA_ but not the same as the
Union Carbide resins as explained in my earlier post).

It would be helpful in my evaluation of possible replacements if you
would take a few minutes to answer the following questions (answers
should be e-mailed directly to me).

    Do you use polyvinyl acetate resins in your work?

    If yes:

        What manufacturer/type and grade do you use?
        How and why do you use it?
