Do you happen to know what is the chemical nature of the said tackifiers?
It
might help when determining what is the nearest equivalent of Vactra
locally. It is not immediately relevant but might become so in the New
year.


I don't know what the tackifier is. KBCtools.com which has operations in
Canada has a
product called EEZ Way oil. Various weights are listed. Calling them
might be a good
idea. Sadly, McMaster-Carr doesn't ship to Canada obtaining small amounts
of vactra would
be easy.


Dealing with the Vancouver branch of KBC tools has its drawbacks. I
generally try to avoid them if I can. There is a local office of Shell
Canada with helpful staff whom I would probably approach if it became
relevant. Or I could use the doughnut method someone suggested in the past
:-)
Either way I thought it would have been useful to know a little more of the
actual science involved. But not essential...
