| Elastosil M 4470 |
 |
RTV-2 Siliconkautschuk/ RTV-2 Silicone Rubber
ELASTOSIL M4470 is particularly suitable for moulding applications in which high elongation and tear strength can be sacrificed in favour of excellent deformation resistance and thermal stability, eg, for making moulds of models with no or only minor undercuts if good heat dissipation and high rigidity are required.
Typical applications are moulds 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. |
