Simpact™ 85A
Simpact™ 85A 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.
