I'm trying to speed up my infusion work process - normally when the resin infusion is complete, I turn off the vacuum. Then leave overnight, then post cure.... I could transfer to the oven straight after turning off vac - any suggested ramps for this to achieve fast cure and 60-70 degree post cure?

Thanks,
James

If the part is purely cosmetic it may be worth trying a Urethayle Acrylate resin as it is possible to add 1-2% of cobalt to the resin before adding the catalyst ( DO NOT MIX COBALT WITH THE HARDENER, IT WILL EXPLODE ). Often these have a much lower viscosity than epoxies and subsequently infuse much easier. The cure times depending on the size of the part can be very quick indeed.

I infused a car bonnet where I was able to remove the part from the mould in under 15 mins. Also if using UA resins with cobalt be careful not to leave large amounts of mixed resin in a bucket as it will exotherm very quickly. As an experiment I left 1/2 a pint in a bucket with a thermocouple in the resin, it reached 250 degrees Celsius in no time.
