Mold Star 15 SLOW Moldmaking Silicone Rubber - Trial Unit
TEAR RESISTANT - Mold Star silicones cure to soft, strong rubbers which are tear resistant and exhibit very low long term shrinkage
HEAT RESISTANT - Cured Mold Star rubber is heat resistant up to 450°F (232°C) and is suitable for casting low-temperature melt metal alloys
CURING- Allow Mold Star 15 SLOW silicone rubber to cure for 4 hours at room temperature (73°F/23°C) before demolding.
VACCUM DEGASSING - Although not necessary, vacuum degassing helps eliminate any entrapped air in pourable silicone rubber
MOLD PREFORMACE - The physical life of the mold depends on how you use it (materials cast, frequency, etc.). Casting abrasive materials such as concrete 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
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. 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, concrete 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. Note: THI-VEX® is NOT compatible with Mold Star® rubbers.MIX RATIO: 1:1 by volume; POT LIFE: 50 mins; DEMOLD TIME: 4 hrs; SHORE A: 15; COLOR: Green
