Mixing Instructions:

  1. Weigh out the required amount of Epoxosil RTV-1116.

  2. Measure the required amount of catalyst.

  3. Mix thoroughly, scraping both the bottom and sides of the mixing container.

  4. Evacuate mixture @ 29 in Hg for 3-4 minutes to insure a void-free casting.

  5. Pour into unit, cavity or mold.

Cure Schedule:

Overnight at room temperature (12-16 hours) @ 72ºF.  Faster tack-free surfaces achieved using varied catalysts.
