Smooth-On Mold Star 15 SLOW Silicone Rubber Kit
Smooth-On Mold Star 15 SLOW Silicone Rubber Kit
Mold Star rubbers are easy to use platinum silicones which are mixed 1A:1B by volume (no weighing scale necessary). Mold Star silicones feature relatively low viscosities and vacuum degassing is not required for most applications. The pot life of Mold Star 15 SLOW is 50 minutes and cure time is 4 hours at room temperature.
Mold Star silicones cure to soft, strong rubbers which are tear resistant and exhibit very low long term shrinkage. Molds made with Mold Star will last a long time in your mold library and are good for casting wax, gypsum, resins, and other materials. Cured Mold Star rubber is heat resistant up to 450 F (232 C) and is suitable for casting low-temperature melt metal alloys.
Mold Performance & Storage - The physical life of the mold depends on how you use it (materials cast, frequency, etc.). Casting abrasive materials can quickly erode mold detail, while casting non-abrasive materials (wax) will not affect mold detail. Before storing, the mold should be cleaned with a soap solution and wiped fully dry. Two part (or more) molds should be assembled. Molds should be stored on a level surface in a cool, dry environment.
