- Reproduction Molding
- Application Details
- Due to its good resistance to all common reproduction materials. e.g. casting resins, concrete, as well as the superior mechanical properties, CENUSIL® 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, CENUSIL® M 820 A/B is also suitable if absolutely accurate copies of models are required.
