Poly-Optic® 1420 Clear Casting Resin is a two-part, liquid polyurethane resin that cures (RTV) to a water-clear, Shore D85 plastic. 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.
Vacuum 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.
WARNING: This product contains Phenylmercuric acetate (CAS 62-38-4), a chemical known to the State of California to cause reproductive harm. For more information, go to www.P65Warnings.ca.gov.
