Happy Days:
Thanks gentlemen :D

Epoxy generally takes longer to cure, has a set mix ratio and can cure in a vacuum. Poly cure time is dependant on amount of catalyst used and usually comes mixed with styrene which evaporates during curing.

That’s the most interesting bit. :?:

Evidently,  in Epoxy glue/resin the hardener forms an integral part of the adhesive compound.
In polyester resin the hardening is triggered by the addition of a catalyst which presumably remains within the cured compound or becomes part of the volatiles’ and evaporates off.

Thanks for that Joe. I do trust you’ll be staying around :)  to inject any further little gems of knowledge you may have into this otherwise rather drab & uneventful forum! :roll:  (I’m only joking lads. :D  Don’t start PM’ing me a load of hate mail. :lol: )

As always I shall endeavor to make your life a little less drab Keith  \:D/
