Heat-set adhesive

This is in response to Rebecca Cameron's inquiry on "Ademco tissue".
This product seems familiar, but off-hand I might suggest that since
you have used a few aliphatics, a few aromatics one chloro, one
ketone, one ester and one alcohol, you might want to sit down with
your Teas chart (see John Burke's article on "Solubility parameters:
theory and application" AIC Book and Paper Annual 1984, v.3)
<URL:http://palimpsest.stanford.edu/byauth/burke/solpar/> and note
the areas of solubility windows you might create by mixing some of
the chemicals you have already tried or adding some (the glycol
ethers might be useful or nitros). On the other hand, some tissues
made in the 60s used a mix of wax, resin and in some cases a Yes!
Paste-like adhesive which require the use of a narrow window of
solubility caused by aging or warm water or solvent exposure over
prolonged periods.  Hope this helps,
