- Application Details
As a low-Shore addition-curing RTV-2 silicone rubber that cures without undergoing dimensional shrinkage, ELASTOSIL® M 4119 is extremely suitable for casting all common reproduction materials, particularly if accurate copies of models with pronounced undercuts are required. Perfect mold making material for very fast de-moldings.
Processing
- Mix components A and B in a ratio of 1:1.
- Important note: The platinum catalyst is contained in component A.
Caution:
- A and B components may only be used together if they have the same batch number.

Safety & Health
- Safety Note
- Components A and B of the addition-curing grade ELASTOSIL® M 4119 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 apply.
