Yes Thank you.
I might have read a similar article.
The epoxy resins I'm using are way different from the ones I was using when I read that article.
The hardening process is more linear
Blush free low allergy resins 2:1 resin / hardener
Fully re-actable viscosity modifiers
Which is why I'm revisiting the the idea of freezing
The multi generation refreeze mix is dodgy.
It does allow laminate, glue & fill into a single day operation.
The fill layer would suffer most from any strength degradation as it is a two or more thaw.
I've reasoned if the mix flows smooth off the trowel it's OK.
Certainly don't want a lumpy fill layer
I'll work on better batch control.
Maybe a silicone ice cube tray filled with bogcicles.
Add dye at thaw to help identify sanding
Good comment "making your own pre-preg"
This could be a solution for tabbing in finished panels
without making a mess.
Wet out some lengths of tape.
Interleave with peel ply.
Package in Sarin Wrap
Freeze flat like Filo Pastry
Transport Thaw and apply at prepared work site.
Remove peel ply when dry.
Thanks for the idea
