You quote curing times for your laminating resin at 60c , will it cure properly at lower temps given enough time?

As long as you have mixed correct ratio,epoxy will cure a very lw temperature it just takes longer to cure,you could introduce some ie energy to set off the epoxy and give it higher mechanical properties. 

Cheers for the info, it is taking me a bit of time to work out how to navigate the forum, hence the delay in replying ( only just found your post )
