Poly-Optic® 1411 ES7 Clear Casting Resin


Poly-Optic® 1411 ES7 Clear Casting Resin is a two-part, liquid polyurethane resin that cures (RTV) to a water-clear, Shore D80 plastic. This is the slow version of Poly-Optic® 1411 Clear Casting Resin - it has a 400-minute pot life and 48-hour demold time. This product is often used for large pours and exhibits minimal shrinkage on cure compared to polyurethane resins with faster cure times. This product has a simple 1A:1B mix ratio by volume. 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.
