Using Techniques:
1. Formula A: CW200 Epoxy Resin: Silica Filler: Mixed Anhydride Hardener
= 100:200:30
2. Formula B: CW200 Epoxy Resin: Alumina Filler: Methyl Tetrahydr Opthalic Anhydride = 100:350:36
3. Operate Techniques: Put the epoxy resins in vacuum reactor system first, heat to 130°C and melt it, put the pre-heated filler, vacuum degassing 5 mmHg for twenty minutes than release the vacuum, put the hardener than pouring-in the moulds, after that put in the heater on 130°C to cure.
4. Curing Condition: 130°C curing for 24 Hours to de-mould.
The Properties of cured:
Formula A (Silica Formula) the curing technics with the mechanical and electrical properties of cured.
