I'm using Papi and occasionally DOA if the mix has high(er) solids.
Typically everything pours very easily without DOA.

I have also used PEVA quite a bit for wax based hybrids, as well as
melting
asphaltum into the wax.
The best combination I've found yet is of HTPB and powdered wax. The
Theencapsuates the powdered wax, yet allows for the lower melting point.
wax greatly increases the surface area of the HTPB, allowing it have a
high
regression rate. You can add in metals to this as well.

Out of curiosity, which isocyanate are using to cure the HTPB? Any
plasticiser?
Thanks,
James.
