Many of us have seen epoxy tooling dough. My question is can I post cure the tool so it can be used in an oven? I only need 180f degrees to cure.
I can just say: Check the datasheet. This should give you answers.
There are so many doughs, and not all will work.
There are lots of companys who make high temp tooling dough, but the trick is that it needs to be applied as near void-free as possible or you will end up with all kinds of blisters. I push progressive balls of dough into a slurry made of dough and hi temp laminating resin. Seems to do the trick.
Actually at 180F even some good R/T doughs should work nicely.
Who makes the dough you guys use? I have used the one from Polymer Composites and it works ok for room temp molds.
I use a product from Freeman Supply designated 1020, it has a published deflection temp of 190F. But I’ve never tried post cure.
What kind of dough is it? Is it basically a chopped strand/resin mix that you then add hardener too in a fashion similar to kneading bread?
I post cured a room temp cure tool of that nature on Monday past to 120 degrees C and it seems to be fine. Im only using it for two or three parts though…
