A high solids molding rubber based on natural latex. Apply in layers. It is not pre-vulcanized and must be vulcanized by either post curing at 110°F for four hours or permitted to stay at room temperature for 5 days. The mold may also be vulcanized by placing it in boiling water for 2 hours.
Mold Rubber is recommended for use with the following materials:
• Portland Cement
• Limited runs of polyester, wax, epoxy or some metals.
NOTE: The higher the degree of exotherm, the more difficult it is to cast into natural latex. It is recommended that all masters be sealed well. Mold releases should be used as an aid to remove the casts.
