- Application Details
As a medium-Shore A addition RTV-2 silicone rubber that cures without undergoing dimensional shrinkage, CENUSIL® M 830 A/B is extremely suitable for casting all common reproduction materials.
Processing
Important note:
The platinum catalyst is contained in Component A
Caution- A and B components may only be used together if they have the same batch number.
- To ensure optimum flow of the material, the components must be stirred thoroughly before they are removed, or processed in their containers.
