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.
The platinum catalyst is contained in component B.
Only components A and B with the same lot number may be processed together!
