Castaldo Jewelry Mold Release Spray is pure silicone oil in an aerosol can for use in releasing wax patterns from rubber or metal molds.

Castaldo Jewelry Mold Release Spray is safe, non-toxic, colorless, odorless, greaseless and long lasting. It contains no CFCs, no VOCs (volatile organic chemicals) and is specially formulated not to damage molds made of natural rubber, such as our White Label®, Gold Label® and No Shrink Pink® jewelry molding rubber.

It is completely non-flammable and non-explosive, unlike most other mold release sprays.
