| ReoFlex® urethane rubbers offer superior physical and performance properties for production casting of wax, plasters, and resins. ReoFlex® urethanes are available in 20A, 30A, 40A, 50A and 60A Shore hardnesses and feature convenient one-to-one by volume mix ratios. Vacuum degassing is not necessary and ReoFlex® rubbers cure with negligible shrinkage to a durable rubber that will last in production. ReoFlex® “Wet” rubbers will shrink somewhat over time vs. “Dry” formulations. ReoFlex® mold rubbers are used for a variety of applications including making molds to reproduce sculpture and architectural elements, as well as for making special effects, toys and prototypes. Vibrant colors can be achieved by adding So-Strong® Color Tints, available from Smooth-On. Casting Concrete? Look into the VytaFlex® series of urethane mold rubbers. VytaFlex® urethanes were formulated specifically for casting concrete / pigmented concrete and feature Smooth-On’s exclusive ‘V-Polymer®’ technology.&& |
