I dont use the Easy Composites pattern coatings, but I do use Scott Bader Primecoat and Glosscoat which will be very very similar in their chemistry - so based on that, I would expect they will have around a 25-30 minute pot life at 23C and 2% catalyst. This will be extended if you are thinning with acetone at all, and of course temperature will effect.
As with most polyester resins, you shouldn't have an issue dropping to 1.5% assuming you are working at around 25C - you just want to make sure you give it sufficient time to fully cure. If you are under 25C, I wouldn't drop the catalyst. In fact, I wouldnt drop the catalyst unless you're over about 32C. It's better to catalyze at 2% and just mix smaller batches.
I'm sure the EC staff will comment soon and can confirm, so just take my comments as a bit of a working idea in the meantime. It's possible these coatings are promoted completely differently to the Scott Bader coatings and I'm way off with my estimations, but that is what I would assume if I were working with them.
