Castaldo's new Rapido Silicone is the fastest curing, heat vulcanized rubber for wax-injection production rubber molds. Cures in just 9 to 20 minutes, depending upon mold thickness, at only 200°F (93°C).
Use it to make powder-separation or hand-cut-separation molds. And, like all silicone rubbers, it's eassy to use and requires no release agents when de-molding.
