Outgassing / Boiling of IN2 Infusion Resin

I've just infused my first test piece, a carbon/foam sandwich using your IN2 Infusion Resin and I am seeing *a lot* of outgassing from the resin under full vacuum. Small bubbles are visable within the within the resin transfer mesh and continue to form/appear as long as there is a hard vacuum. Will this compromise the strength or the cosmetic finish of the finished part? (I haven't de-molded yet.) Is there any way to elimitate outgassing?

Thanks,

Phil.

I've just been out to the workshop and the vacuum gage has dropped from -1bar to around -.8 overnight... so I do have a leak after all. I only did a short (5-10min) vacuum check before introducing the resin (impatients I guess.) Lesson learned - I'll perform a full 30min vacuum integrety test in future.

Apologies, mea culpa!
