Product Description

Simpact™ 60A

Simpact™ 60A urethane is a low odor, fast-setting urethane elastomer which offers very high tear strength, impact resistance and wear resistance. Simpact™ urethanes are phthalate free, mercury free and MOCA free. Simpact™ urethanes pour easily. Working time is 4 minutes, handling time is 2 hours and full cure time is 48 hours at room temperature.

Cured rubber has exceptional performance characteristics and dimensional stability. Simpact™ urethanes can be colored with SO-Strong™, UVO™ or Ignite™ colorants. Simpact™ urethanes are suitable for making impact resistant props, prototypes and display pieces.

This material may congeal if exposed to cold temperatures. To reconstitute, Part A & B must be heated to 90°F (33°C) then thoroughly mixed to an even consistency.

ReoFlex™ 30

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.
