A pure duplication silicone, without dyes or filling materials ... crystal-clear. Its fast resilience and high tensile strength ensure an absolutely precise reproduction of your models. The transparency of the 1:1 silicone (Cast A + Cast B) prevents bubble formation when casting, therefore light-curing materials can be processed safely. We recommend the use of Matrix Cast Clear for the production of composite restorations in the anaxFORM Clear flasks. A Shore hardness of 22 makes it easy to divest the models.
