Two-component RTV silicone rubber compounds for moldmaking are suitable for mold masters for molding with polyester resin, epoxy resin, urethane foam, wax, plaster, and low-melt-point metal alloys. These RTV rubber compounds allow accurate reproduction of the shape of the original. They are easy to use and are thus used widely in industrial applications, as well as by hobbyists looking to create the perfect replica. |
 |
Workability |
| |
The base compound and curing agent are mixed and then poured into the mold to create a silicone rubber mold quickly. Workable time and cure time can be adjusted. |
|
Mold-releasability |
| |
The cured rubber releases easily from the mold, so mold-release agents (soapy water, wax, etc.) are unnecessary. |
|
Dimensional stability |
| |
These rubbers offer good dimensional stability, with little shrinkage. |
|
Flowability |
| |
They have excellent flowability, so the original form is reproduced accurately. This includes even intricate shapes and details such as fingerprints and wood grain. |
|
Heat and chemical resistance |
| |
These rubbers have outstanding resistance to heat and chemicals. |
|
Deep-section curability |
| |
Moldmaking RTV silicone rubber compound cures uniformly throughout the mold, regardless of thickness. |
|
Non-exothermic |
| |
No heat is generated during curing, meaning no adverse effects to the original. |
