CONDENSATION SILICONE
- Hydrophobic
- Poor wetting
- Low stability
- Limited shelf life
- Catalyst – tin
- Byproduct – C2H2O4 (ethyl / methyl alcohol) – large byproduct high polymerization shrinkage
– highest dimensional change, therefore least preferred imp material
- Just economical
- Wear vinyl gloves only
- Wait for 20-30mins before pouring - for stress relaxation
