Could have been a summer day, but the temperature in my workshop never rises above 25°c. 1.5% gives a little more pot life, but not much. Still cured perfectly. But I am a conscientious resin stirrer. Thanks, I'd found the pattern coat was similarly 10-15 mins with at least a 60 sec stir, cutting it back to 1.75% seemed to make no difference. I'll go with 1.5% and be efficient, I think the data sheet says you can go down to 1%.

Pattern coat High gloss pot life and catalyst ratio

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....

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....

Thanks both, but that doesn't answer the original question.

Did you find that it is too fast for application? The data sheet says 2% for usual 20 Degrees C, if you could reduce it to 1.5% as a test but then you should also compensate for the lesser catalyst%...

Assuming I'm close with my estimation for pot life at 2%, I'd estimate you'll be around a 40 to 45 minute pot life at 1.5%. If you're concerned, the easiest thing to do is just do your own gel test....

If it's too fast for your needs, you could buy polyester inhibitor. This can easily double or quadruple the geltime without risking uncuring resin.
