Application:
Platinum cure RTV silicone for jewelry molds is great to make molds either with simple or intricate patterns, like artificial jewelry, resin jewelry, artificial necklace etc.
Feature:
- High Shore A hardness (approx.40)
- Good transparency, high tear strength
- Almost nil shrinkage, cure at room temperature
- Outstanding resistance to common casting resins
- Food grade silicone(environmental, odorless and nontoxic)
- High chemical resistance to aggressive components of some types of resins
