OK, now, the Epoxy I normally use, trade name Araldite, is two part and
the warning on the side of one of the tubes, which I am holding at the
moment says (next to the "irritant warning cross) "contains reaction
product Bisphenol A-Epichlorohydrin Epoxy Resin (number average molecular
weight <700).

It sets fully in around 24hrs at normal room temperature though setting
can be speeded up by heating. No autoclave.

Polyester resins, often used as fillers in car body repairs have a very
distinct smell and Araldite smells nothing like them.

Please explain.

Stuart.
