| Silastic 3120 Base&Dow Corning 1 Caralyst |
 |
General purpose silicone mold making rubber containing Iron oxyde for heat stability.
3120 Base with 1 Catalyst is recommended for casting low melt metals.
SILASTIC 3120 Moldmaking Rubber is a two-component material consisting of SILASTIC 3120 Base, which when mixed with DOW CORNING 1 Catalyst cures at room temperature by a condensation reaction.
A range of materials can be cast into the cured silicone mold: plaster, polyurethane, polyester and other reactive resins are materials typically used and especially low melting point metal alloys. |
