Product Description
Rebound™ 25
Rebound™ 25 is an easy-to-use platinum-cure silicone rubber which self-thickens for making brush-on molds of almost any model. Mixed 1A:1B by volume (no scale necessary), Rebound™ rubber can be applied with a brush or spatula to vertical surfaces without sagging and will cure with negligible shrinkage to a flexible rubber.
Simpact™ 80A-II
Simpact™ Series urethanes are low odor, fast-setting urethane elastomers which offer very high tear strength, impact resistance and wear resistance. Simpact™ urethanes are phthalate free, mercury free and MOCA free. Simpact™ urethanes pour easily. Simpact™ urethanes have fast handling times, allowing them to be demolded quickly. 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, dimensionally stable prototypes and rubber mechanical parts. Simpact™ 80A-II offers exceptional UV resistance and can be combined with URE-FIL™ 13 to create high strength simulated vines, branches, etc. for zoos and other themed environments. See separate Vine Making bulletin for instructions.
