The technical sheet doesn't specify the pot life with a 2% ratio, can some one confirm? Also, if I reduce the ratio to 1.5% what will the pot life be and will that still give a complete cure?
Thanks

Just the fact that you are making a mould means that everything you do with the pattern and the making your mould should be well cured!

Having a proper cure is key to moulding and releasing well so save yourself the risk of any stickups with making your mould from the pattern and making future new parts from your moulds with being certain that all is 100% properly cured. Check your temperatures and catylst % all the way through the processes but particularly the pattern surface coat and new mould gel coat.
