Mixing Instructions:

1. Pre-mix contents of each container before use to assure uniformity.  Some slight settling may occur, but it will be soft and easily re-incorporated.

2. Measure out equal volumes of each component and mix together thoroughly. Be careful to scrape sides and bottom of container to incorporate all unmixed material, or serious loss of physical and electrical properties will result.

3. De-air (if necessary) at 0.5 cm. Hg. for 5 minutes.

4. Pour into cavity or mold.

5. Re-cover both containers immediately after each use as deterioration can result.

Cure Schedule:

Allow 16 hours at 77 degrees Fahrenheit. To accelerate cure allow 2 hours at room temperature then 130 degrees Fahrenheit for 2 hours.
