- Application Details
- Due to its good resistance to all common reproduction materials. e.g. casting resins, concrete, as well as the superior mechanical properties, CENUSILĀ® M 820 A/B is especially suitable for all molds of models with extensive undercuts.
- As a low-Shore A addition silicone rubber that cures without undergoing dimensional shrinkage, CENUSILĀ® M 820 A/B is also suitable if absolutely accurate copies of models are required.

Safety & Health
- Safety Notes
Components A and B of the additions-curing grades CENUSILĀ® M 820 A/B contain only constituents that over many years have proved to be neither toxic nor aggressive. Special handling precautions are therefore not required, i.e., only the general industrial hygiene regulations regulations apply.
