Mixing Instructions:

Pre-mix Part A and Part B separately. Then measure out parts by weight. Mix thoroughly scraping the sides and bottom of the container. Evacuate @ 29in. Hg for void free casting. Pour into mold or cavity.

Cure Schedule:

Room temperature cure @75°F with full properties after 24 hours.
To accelerate cure, allow 2 hours @ room temperature, then 2 hours @ 125°F.
For higher service temperature, use Polycure 110.
