It cures to a tough, impact and heat-resistant plastic that can be polished and machined and is used extensively in prototyping applications. Heat cure (150°F - 180°F) is required to achieve optimum physical properties. When cured at room temperature, the result is a brittle, glass-like casting.\u003c\/p\u003e\n\u003cp\u003eVacuum and\/or pressure casting techniques are recommended for this product. Cure inhibition can occur when casting this resin in tin-cured silicone rubber molds – use a platinum-cured silicone rubber mold if working with silicones.\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"height: 20px; width: 25px; margin-left: 5px; margin-right: 5px; float: left;\" src=\"https:\/\/polytek.com\/content\/images\/Prop65_Warning_Symbol.png\" alt=\"\" data-media-element=\"1\" data-fid=\"3630\" data-delta=\"1\"\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e This product contains Phenylmercuric acetate (CAS 62-38-4), a chemical known to the State of California to cause reproductive harm.
