ELASTOSIL® M 4470 is particularly suitable for molding applications in which high elongation and tear strength can be sacrificed in favor of excellent deformation resistance and thermal stability, e. g., for making molds of models of models with nor or only minor undercuts if good heat dissipation and high rigidity are required.


Typical applications are molds with

  • high rigidity for foaming resins (for foaming polyurethanes, it is advisable to use a barrier coat!)
  • high swelling resistance to components of casting resins, such as styrene in the case of polyesters
  • high thermal stability and heat dissipation for casting low-melting metal alloys

ELASTOSIL® M 4470 is cured by adding Catalyst T37 for long pot lives and curing times, or Catalyst T40 for short pot lives and curing times.


Thin-walled molds are best suited for casting low-melting metal alloys (melting point: 300 °C max.) and should be placed on a sheet of aluminum or other material with high thermal conductivity. Before the casting process, the old should be post-cured for a few hours at about 150 °C. In order to improve wetting by the molten metal, a thin layer of extremely fine silicon carbide, graphite powder or acetylene black should be applied to the mold surface.
The first castings have normally to be discarded since the rubber still emits gases, giving the surface of the casting a pockmarked appearance.
The pot life is the period of time at 23 °C / 50 % rel. humidity during which the catalyzed mix to attain a viscosity of 100,000 mPa s and still be just pourable
