Pourable, addition curing, two-component silicone rubber that vulcanizes at room temperature.
- High Shore A hardness (approx. 55)
- Fast and non-shrink cure at room temperature which can be accelerated considerably by the application of heat
- Good flow
- Excellent long-term stability of the mechanical properties of the vulcanizate
- High tear strength
- Outstanding resistance to common casting resins
Due to its outstanding resistance to casting resins as well as its superior mechanical properties, ELASTOSIL® M 4670 A/B US is perfectly suitable for all molds of models with only slight undercuts that are to be reproduced in casting resins, and a high inherent rigidity of the molds is required.
