Castaldo® QuickSil® molds are not weak, delicate prototypes that can be used only once or twice. They can produce dozens or hundreds of injections, depending on the complexity of the design. They do not deteriorate or become soft over time but instead last for decades. QuickSil® makes production molds but is also ideal for short runs or the last-minute emergencies that are typical in any jewelry manufacturing business. QuickSil® is a two-part room temperature vulcanizing (RTV) silicone rubber putty that is easily mixed by hand. It is not a liquid rubber, making it ideal for those without a vulcanizer or a vacuum pump. Molds cure ready-to-use with 0% rubber shrinkage in only 15 minutes at room temperature. QuickSil® molds are easy to cut and require no lubrication, powder or release sprays as the rubber is self-lubricating. Instructions. Part A MSDS. Part B MSDS.
