Pourable, addition-curing, two-component silicone rubber that vulcanizes at room temperature.

Due to its outstanding resistance to concrete and superior mechanical properties, ELASTOSIL M 4630 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 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 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
