SYSTEM FOR ELECTRICAL CASTING
EPOFIL -60- HF is a Filled solvent less, modified Epoxy Resin System. It is cured at room temperature with aliphatic polyamines to a solid, infusible mass and does not evolve any volatile substrate while curing.
Typical Properties
| Unit | Epofil-60-hf | Epoxy hardner pam | |
|---|---|---|---|
| Appearance | Viscous | Clear pale yellow liquid | |
| Color | Brick red | -- | |
| Sp gr | Gm/cc | 1.5 – 1.7 | 0.9 – 0.95 |
| Viscosity by BF at 27°C | mPa.s | 35,000 – 45,000 | 100 – 300 |
Mixing Proportion
- Epofil-60 -hf : 100 parts
- Epoxy hardner pam : 4- 5 parts
- Pot life : 15 – 20 mts at rt
Take required quantity of epofil-60-hf in a mixing chamber and add epoxy hardner pam in above proportion.
As the reaction is directly proportional to mass and temperature, users are advised to mix in small batches so that material can be consumed well before the expiry of pot life.
Mixing Proportion
- At 20°c - 48 hours
- Or at 30°c - 20 – 24 hours
- Or at 40°c - 16 – 20 hours
