Contains more pure natural gum rubber than Castaldo White Label, making Castaldo Gold softer and more pliable. The superior qualities of Castaldo Gold make it the ideal rubber for difficult molds containing undercuts, filigree or multiple settings. Easy to pack and highly flexible so that wax patterns release smoothly.
Vulcanize at 310°F for 15 minutes per 1/4" of mold frame thickness. Rubber is 1/8" thick.
Sold in Strips (2-7/8" x 18") or Rolls of 5 lbs. or 50 lbs. Rolls are 18" wide. Made of natural rubber.
