- Main application: Making cost effective molds.
- Reproduction Molding for Foundry, Arts and Handicrafts.
- Application Details
- Being a kneadable grade that produces vulcanizates with high hardness and mechanical strength, ELASTOSIL® M 1470 is particularly suitable as an impression material, i. e., for molding models with only a slightly structured surface or for small models with no or only minor undercuts by either impressing a slab of catalyzed rubber onto the model surface or pressing the model into the surface of the rubber slab.
- Molds made of ELASTOSIL® M 1470 can be used with all common reproduction materials.
Processing
- ELASTOSIL® M 1470 is cured by adding Catalyst Paste T 40. The pot life is the period of time at 23°C, 50% relative humidity during which the catalyzed mix can be applied.

Safety & Health
- Safety Note
- Being a condensation-curing silicone rubber, ELASTOSIL® M 1470 contains 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.
- Catalyst Paste T 40 contains a tetraorganotin compound, is flammable and may cause irritation in contact with the eyes and skin. Adequate protective measures are required.
