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.

Final Color: Orange

Physical Properties Information

Orange Medium Body Physical Properties

Determined at 23°C (72°F) (Tested according to ISO 4328)

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

Dispensing time depends on mass extruded.

Working Time (prior to gellation)

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)

1.0%

Strain in Compression (A modified Modulus of Elasticity)

4-5%

Shore A40

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

Percent of Elongation

70%

Modules of Elasticity

770

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.

Disinfection

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.
