Hi everybody,
I have the same problem with all EG160 moulds I prepared the last months: Taking the part out of the mould shows a perfect finish, but after postcuring in the recommended cycle there are points where it looks like air is trapped. But you could not see it before the curing process... any tips?
Regards and a wonderful christmas for everyone!

Thanks for your thoughts.
I do not think that the sealer is not usable for multiple pulls. In the tooling prepreg guide is written that you can sand the prepreg mould if you have minor imperfections and restore the gloss with the sealer - which makes no sense if you couldn’t use it multiple times.
I am also not sure if it is a good idea to sand the mould with much less than 1200grit because the sealer is not able to close deep scratches. Otherwise this could be the best bet why the sealer came down on the part!
For my part it is not that problem because I wanted to make a prepreg plug out of the EG160 mould to produce a tooling prepreg mould. I already cleaned the surface and try to make the „new“ mould this weekend. But it would be nice to understand what was going wrong.
Perhaps EC staff lets us know their opinion.
