Product Description
XTC-3D™
XTC-3D™ is a protective coating for smoothing and finishing 3D printed parts. Two liquids are mixed together and brushed onto any 3D print. Coating self-levels and wets out uniformly without leaving brush strokes. Working time is 10 minutes and cure time is about 4 hours (depending on mass and temperature). XTC-3D™ cures to a hard, impact resistant coating that can be sanded, primed and painted. Adding colors and metal effects is easy.
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.
