This silicone-based rubber makes molds that cut like butter. Uncured, it has the consistency of soft putty, making it very easy to pack in undercuts and detailed areas. Produces a firm mold with excellent flexibility and tear strength. Strong enough to make complex multi-part molds. Gives waxes a smooth, shiny finish for easy release from molds and less finishing on castings.  Made in Thailand.

Vulcanize at 330°F for 15 minutes per layer of rubber.

Sold in 5 lb. boxes of 2-7/8" x 18" strips.
