  • Addition Curing
  • Fast curing at room temperature
  • Flowable
  • Low viscosity
  • Two-component

As a low-Shore addition-curing RTV-2 silicone rubber that cures without undergoing dimensional shrinkage, ELASTOSIL® M 4115 A/B is extremly suitable for casting all common reproduction materials, particularly if absolutely accurate copies of models with pronounced undercuts are required.


Important note:
The platinum catalyst is contained in Component A

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.

Please check also our brochures and info sheets.


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.
