Castaldo Rapido Silicone Mold Rubber

Castaldo Rapido Silicone Mold Rubber

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.

  • 1/4" (6 mm) thick mold 9 minutes
  • 1/2" (12 mm) thick mold 10 minutes
  • 3/4" (19 mm) thick mold 15 minutes
  • 1" (25 mm) thick mold 20 minutes

Rapido™ silicone strips are 1/4" thick x 2-7/8" wide x 18" long. Sold by the pound. Made in USA.
