Product Description

SILISIL RTV MD-Soft 0020 is a room temperature vulcanizing 2-component silicone of the MD — Medical (Dental, Podiatry, Skin Contact)series (Addition (Platinum), Soft Consistency, RTV-2) — Ultra-soft soft-touch silicone Shore 00 23 — extreme elasticity for medical and FX applications.

The mixture is prepared in a 1:1 ratio by weight . Pot life at 23 °C is approximately 25 minutes, demolding is possible after approximately 70 minutes, and complete curing takes 24 hours. Temperature resistant from -40 °C to +200 °C.

Key property

Extremely elastic (770% elongation at break) at Shore 00 23 — the softest flowable variant of the MD series for the most extreme soft-touch and FX applications.

What distinguishes SILISIL RTV MD-Soft 0020

Ultra soft (Shore 00 23)
Ultra-soft (Shore 00 40) — conforms to extreme geometries and transfers ink even to highly structured surfaces.
Maximum elongation at break: 770%
Skin-friendly for lifecasting
Tested for direct skin contact — suitable for body casts of face, hands and torso.
Very low density 0.95 g/cm³
Pot life 25 minutes
Very short processing time — suitable for high-throughput production with short mold cycles.
Mixing ratio 1:1 by weight
Simple 1:1 ratio — hand-mixable without a precision scale, ideal for workshops and hobbyists.

What is SILISIL RTV MD-Soft 0020 used for?

Special effects with maximum elasticity
SFX wounds, stunt doubles, deformation effects and prosthetic attachments with lifelike skin elasticity.
Anatomical soft-tissue models
Training models for soft tissue surgery, plastic surgery and lifelike teaching models.
Robotics and soft grippers
Industrial grippers for very sensitive workpieces — minimal contact pressures and maximum adaptability.
Rehabilitation cushions and compression elements
Pressure-relieving pads for patients with sensitive skin — decubitus prophylaxis and rehabilitation applications.
Sports equipment padding
Soft padding in helmets, shin guards and sports protective clothing with maximum wearing comfort.
Acoustic and vibration damping
Ultra-soft damping elements for audio studios, measuring equipment and vibration-sensitive devices.

Processing

1
Prepare the original
Clean, dry, and dust-free surface at 23 °C — cooler environments significantly extend pot life and curing time.
2
Mix components
Stir base and catalyst thoroughly before use. Weigh out 1:1 by weight. Mix in thoroughly, including container walls and bottom.
3
Vacuum degassing
Briefly degas under vacuum for a pore-free mold — entrapped air is removed and a smooth mold surface is guaranteed.
4
Processing
Pour in a thin stream from approx. 30 cm height — minimal air entrapment.
5
Vulcanize and demold
At 23 °C, demolding is possible after approximately 70 minutes, with complete hardening after 24 hours.

Important Notes

Avoid crosslinking inhibitors
Addition system (platinum) — sensitive to sulfur, amine, tin, and phosphorus compounds. Avoid contact with latex gloves and PVC plasticizers.
Storage and Shelf Life
Shelf life of at least 12 months in unopened original container when stored in a dry, cool place (10–25 °C). Consult the SDS before opening.
Available containers
1 kg + 1 kg, 5 kg + 5 kg. Other container sizes available on request.
Compatibility
Compatible with polyurethane, epoxy, and polyester casting resins. For aggressive resins, apply a release agent.

Frequently asked questions about SILISIL RTV MD-Soft 0020

Practical application and design questions — answered by SILITECH.

SILISIL RTV MD-Soft 0020 is a 2K silicone from the MD — Medical (dental, podiatry, skin contact) series (Shore A 00 23, translucent). This ultra-soft, soft-touch silicone (Shore 00 23) offers extreme elasticity for medical and special effects applications, making it suitable for high-elasticity special effects and related applications.

At 23 °C, the pot life is approximately 25 minutes and the demolding time approximately 70 minutes. Complete curing takes 24 hours.

SILISIL RTV MD-Soft 0020 is an addition-based (platinum) soft-consistency system. This addition-based system (platinum) is sensitive to sulfur, amine, tin, and phosphorus compounds. Avoid contact with latex gloves and PVC plasticizers.

SILISIL RTV MD-Soft 0020 is mixed in a 1:1 ratio by weight (base to catalyst). Homogenize both components separately before mixing, then thoroughly incorporate them – including the container walls and bottom.

SILISIL RTV MD-Soft 0020 achieves a Shore A hardness of 00 23 (ASTM D 2240), a tensile strength of 1.2 N/mm² (ASTM D 412), an elongation at break of approximately 770% and a tensile strength of 3.5 N/mm (ASTM D 624).
