Define Silicone RTV Mold-Making System:

Silicone RTV Mold-Making System is a complete mold making system that can be used to make virtually any type of mold.  Silicone RTV is a two component, tin catalyzed, room temperature cured silicone rubber. It is designed as a 25 Shore A mold rubber – meaning it is flexible, good dimensional stability, and good elongation and tear strength. It has very low shrinkage, excellent long-term retention of rubber properties and accurate detail reproduction. It is excellent for casting cement, vinyl, wax, plaster, low-melt metals, urethane resins, epoxy resins and polyester resins. It is a safe product to use when directions are followed fully.  TAP Silicone has a 4-8 hour demold time allowing two part molds to be completed in one day.
