Resin Embedment
Resin embedment is one of basic skills for material research. We currently provide EpoxiCure 2 Resin for lab general use.
- Clear, general purpose epoxy system
- 6 hr cure time at room temperature
- < 40°C Peak Temperature
- ~80 Shore D Hardness
- Young's modulus: 120+/-10 GPa (tested in our lab)
Prcedure of mixing resin
- Prepare plastic embedment mold, seal the edges with wax or tape. Cover inner surface with very thin layer of Vaseline.
- Align your specimen(s) in the mold. You may use clips on the shelf or a bit wax to hold the position.
- Weigh resin and hardener: Measure resin part and hardner part 1:4 volume ratio, or 100 part resin with 23 part hardner by weight.
- Mix well with wooden tough presser. Poorly mixed resin could be either soft or brittle.
- Pour resin mix into the mold and leave overnight to set.
- Leave leftover resin in the cup to set. Any uncured resin is considered as chemical toxic. After set, the waste resin can be dumped as regular trash.
Tips
- Note: Use same type of hardner and resin, mismatched hardener doesn't provide desired epoxy hardness.
- Note: Avoid using exceesive vaseline in the mold, which may prevent setting.
- Note: Shapie marks may be smeared or dissolved in resin mix. Use pensile mark on embedded objects or include a printed label.
