Doug, we use BJB's 788 for smaller parts (less than 5"). Has decent
mechanicals, HDT listed at 175dF @66 psi, don't know if that fits what you
need. Regards, Bob Olsen, Protogenic

Subject: [rp-ml] Lense urethanes

Which urethanes are being used by companies doing
lense reproduction or prototyping. I am looking for a
high temperature urethane or maybe even an epoxy. It
must be moldable in a silicon rubber mold and be
tintable and durable as well.
