- Application Details
- Due to its outstanding resistance to concrete and superior mechanical properties, ELASTOSIL® M 4630 A/B is ideal for use in molds for making concrete reproductions of models with deep undercuts.
- As a low-shore, addition-curing RTV-2 silicone rubber, which cures without dimensional shrinkage, ELASTOSIL® M 4630 A/B is also extremely suitable for casting all other common reproduction materials, especially casting resins where absolutely accurate copies of models with pronounced undercuts are required.
Processing
Important note:
- The platinum catalyst is contained in component B.
- Only components A and B with the same lot number may be processed together.
