Polyurethane, latex or metal molds should be dry and require a coat of suitable release agent. \u003cstrong\u003eUniversal Mold Release \u003c\/strong\u003e(available from Smooth-On) is ideal for this purpose. A liberal coat of release agent should be applied onto all surfaces that will contact the plastic. To ensure thorough coverage, lightly brush the release agent with a soft brush over all surfaces. Follow with a light mist coating and let the release agent dry for 30 minutes.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e\u003c\/em\u003e Shelf life of product is reduced after opening.

If you choose to vacuum the material, subject mixture to 29 h.i.g. mercury in a vacuum chamber until mixture rises, breaks and falls. Allow for 3 to 4 times volume expansion in mixing container.
