Pourable, condensation-curing, two-component silicone rubber that vulcanizes at room temperature.
Special features
good flowability and self-deaeration
high Shore A hardness (approx. 60)
very good heat resistance
high thermal conductivity
outstanding resistance to common casting resins
Application
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
