I just finished a split mold, made of High temp gelcoat + putty reinforcement
Before completing the second halve, I applied 6 easylease coats on the first halve of the mold and the pattern.
I left the mold to cure.
Can I let the mold 5 days before separating the two halves ? Will the easylease still work in 5 days . I know this is semi permanent release but I was wondering if it had a limit in time.

Thanks

Absolutely yes. Semi permanent means that it is possible (but not really recommended) to do several parts without applying the release agent between the cycles.
There is nothing like a time limit for any release agent I know of. But usually you want to make your part (or mold) reasonably soon after applying the release agent, to prevent the mold from catching dust.

Ok , thanks for clarification
I have never been in this situation before , but this time I will leave home and the mold is not fully cured... so I hope this will work fine to open the mold when I will be back in 5 days

It is no problem. I often leave parts for several days or weeks prior to demoulding, to ensure the resin is well cured and reduce print-through. 

Hi Tony,

Just checking in on the support forum over the Christmas break; I can see that you've been well looked after by oakmont and Hanaldo on this one; they're both right that you should be fine to come back to your Easy-Leased part several days later without any problems at all. If you're ever unsure then you can always add one extra application of Easy-Lease at least 1 hr before you lay up but we wouldn't expect any problems either way. One time when we would recommend re-application is if you're pulling the mould out of storage where it's been for months or years, in this case it would certainly be recommended to re-apply, just to be sure that so contamination from storage has interfered with the release agent.

All the best and enjoy your New Year.

Hi Matt

My question was more about demoulding time,
But I think it was answered also on previous posts on the forum
I understood I can let a mold for curing or a closed mold with a cured parts inside for multiple days with no more problem for demolding as long as the release agent was applied during the process.

Thanks again
Have a good end of the year!

No problem Matt
All worked fine when I opened the mold 5 days later.
Really happy with the result
