Poly-Optic® 14-70 Clear Casting Resin

Poly-Optic® 14-70 Clear Casting Resin


Poly-Optic® 14-70 Clear Casting Resin is a two-part, liquid polyurethane resin that cures (RTV) to a water-clear, Shore A70 rubber. This is the only flexible rubber option in the Poly-Optic® Series. Poly-Optic® 14-70 rubber can be blended with Poly-Optic® 1410 Clear Casting Resin to achieve any hardness between Shore D80 and Shore A70.

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.
