Thin PourReprorubber® Thin Pour

Reprorubber® Thin Pour is a two component, addition cured, platinum catalyzed, hydrophobic vinyl polysiloxane. Its two components are poured into a container and mixed to obtain a uniform mixture. It may be used to reproduce surface characteristics. It is able to reproduce surfaces down to submicron particles or scratches. It is cured at room temperature. However, warmer temperatures accelerate the setting time and cooler temperatures slow the setting time.

Final Color: Light Green

Further information on composition is available on MSDS.

Mixing Time

  • 30 seconds, Larger masses may take up to 60 seconds.
  • Working Time (prior to gellation) – 4.0 – 4.5 minutes

Setting Time

8 – 9 minutes. Varies with ambient temperature. Warmer temperatures accelerate the setting time. Cooler Temperatures slow the setting time.

Compression Set (Recovery from deformation)


Strain in Compression (A modified Modulus of Elasticity)

6 – 7%

Shore A30

Dimensional Change

  • After 24 hours –0.50 % Change (negative 0.50% change) this means it shrinks 0.50%
  • After 7 Days –0.50 % Change (negative 0.50 % change) this means it shrinks 0.50%

Tear Strength

200 psi

Flash Point of the polymers used

130°C (266°F)

Ignition Temperature of the polymers used

470°C (878°F)

Fully set material may be autoclaved, but its dimensional stability may be compromised. If allowed to return to room temperature, should return to original shape.


Since material is hydrophobic, immersion in disinfectants is acceptable. The surface color may change due to the disinfectants used.
