Orange Medium Body

Reprorubber® Orange Medium Body is a two component, addition cured, platinum catalyzed, hydrophobic vinyl polysiloxane. Its two components are extruded from a double-barreled cartridge, through a static mixer 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.

Orange Medium Body Physical Properties

Determined at 23°C (72°F) (Tested according to ISO 4823)

Base Paste
Appearance - Homogenous orange-colored runny paste, Filling loading approximately 25% silicon dioxide.

Catalyst Paste
Appearance - Homogenous, grey-colored runny paste, Filling loading approximately 25% silicon dioxide.

Mixed Material
Appearance - Homogenous orange-colored.

Mixing Time (prior to gellation)
Dispensing time depends on mass extruded.

Working Time
2.0 – 2.5 minutes

Setting Time
5 – 6 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)

Shore A55

Detail Reproduction
  • Smaller than 20-micron line
  • Contact Angle @ 0 minutes 65°
  • Contact Angle @ 15 minutes 5°
  • Contact Angle @ 30 minutes 5°
Dimensional Change
  • After 1 hour- 0.30% Change (negative 0.30% change) this means it shrinks 0.30%
  • After 24 Hours - –0.35 % Change (negative 0.35% change) this means it shrinks 0.35%
  • After 7 Days - –0.40 % Change (negative 0.40 % change) this means it shrinks 0.40%
Tear Strength
300-325 psi

Modulus of Elasticity

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, but should not be immersed in the disinfectant for longer than 10 minutes. The surface color may change due to the disinfectants used.

You can take impressions of:

  • All Metals
  • Non Metals
  • Paper or Cardboard Items
  • Ceramic and Glass items

Other Uses Include:

  • Fixturing where semi-rigid structure is desired.
  • Making joints where flexibility is required.
  • Replica is easy to remove - even if there are under cuts or grooves.
  • Cross-sectioning of replica is easily accomplished with a knife or razor.
  • It can then be checked on an optical comparator or microscope.
  • Surface finish replication is exact with excellent optical properties.
  • Replicas are permanent - will not leach or ooze out nor outgas.

  • Wood, Marble, etc.
  • All Plastics
  • Rubber

  • Prototypes of rubber type components such as gaskets, washers, etc.
  • As a mask for high temperature plasma spray of metallic coatings.
  • No more 16 hour cure time as with RTV silicones
  • More accurate than all other RTV compounds
  • Reprorubber® Putty will withstand up to 600°F (or more).
  • Reprorubber® copies can be recopied (copy from a “female mould” yields a male-shaped replica).
