Specific features of ELASTOSIL® M 1470

  • Condensation-curing
  • Heat resistant
  • Kneadable
  • Two-component

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.

ELASTOSIL® M 1470 is cured by adding Catalyst Paste T 40.

Comprehensive instructions are given in our leaflet "ELASTOSIL® - PROCESSING RTV-2 SILICONE RUBBERS".

Detailed information on other mold-making compounds in the ELASTOSIL ® M range is contained in our brochure "ELASTOSIL® M. Mold-Making Compounds For Maximum Precision".

The pot life is the period of time at 23 °C / 50 % rel. humidity during which the catalyzed mix can be applied.



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.
