Mixing Instructions:

  1. Weigh out required amount of Epoxocast EB-502 LV and weigh into it 12 parts Epoxocure 9 per 100 parts Epoxocast EB-502 LV; or 16 parts Epoxocure 11 per 100 parts Epoxocast EB-502 LV.

  2. Mix curing agent in thoroughly.

  3. Evacuate for 2-5 minutes if void-free castings required.

  4. Pour into cavity, mold, etc

Cure Schedule:
