SILISIL RTV MF-Soft 00
SILISIL RTV MF-Soft 00
SILISIL ·

SILISIL RTV MF-Soft 00 is a room temperature vulcanizing 2-component addition silicone (platinum cross-linking, RTV-2) from the MF-Mold & Form range — Ultra-soft silicone Shore A 0 — for skin simulation and FX applications.

The mixture is prepared in a 1:1 ratio by weight (tolerance ±5%). Pot life at 23 °C is approximately 5–7 minutes, demolding is possible after approximately 50 minutes, and complete curing takes 24 hours. Temperature resistant from -40 °C to +200 °C.

Key property

Ultra-soft (Shore A 0) — the right choice for skin simulation, anatomical models and soft-touch applications with maximum elasticity.

What distinguishes SILISIL RTV MF-Soft 00

Ultra-soft Shore A 0
Ultra-soft — almost skin-like consistency for lifecasting, FX and soft-touch applications.
Very low viscosity 1,500 mPa·s
Very low viscosity — flows even into microscopic structures and the finest undercuts.
Very high elongation at break 550%
Very high elasticity — removes aggressive undercuts without tearing.
Translucent
Air inclusions, mold filling, and the embedded original are visible during processing and demolding.
Mixing ratio 1:1
Simple 1:1 ratio — hand-mixable without a precision scale, ideal for workshops and hobbyists.
Fast curing
Rapid vulcanization at room temperature — the mold is quickly ready for production.

What is SILISIL RTV MF-Soft 00 used for?

Special effects and film technology
Skin simulation for mask making, stunt doubles, wound and injury replicas — Shore A 0 corresponds to a soft skin feel.
Anatomical training models
Medical and veterinary teaching models, surgical simulators — lifelike soft tissue imitation.
Soft-touch components and grippers
Robotics and automation grippers for sensitive workpieces — elongation at break 550% and lowest contact pressures.
Acoustic and vibration damping
Ultra-soft damping elements, pads, vibration decoupling in precision instruments and audio applications.
Sports and orthopedic insoles
Cushioning and pressure distribution elements for shoemakers, orthopedic workshops and sports equipment manufacturers.
Prosthetic and rehabilitation applications
Skin-like comfort for individual prosthesis padding — use in rehabilitation and medical supply stores after self-testing.

Processing

1
Prepare the original
The surface to be reproduced must be clean, dry, and free of dust. The ideal processing temperature is 23 °C — cooler environments significantly extend pot life and curing time.
2
Homogenize and mix components
Stir base and catalyst thoroughly before use. Weigh out 1:1 by weight (tolerance ±5%). When mixing, thoroughly incorporate the walls and bottom of the container.
3
Vacuum degassing
For pore-free molds, briefly degas the mixture under vacuum — entrapped air bubbles are removed, ensuring a smooth mold surface.
4
Pour slowly into the mold
Pour from a height of approx. 30 cm in a thin stream into the deepest point — the silicone displaces air independently and reaches all undercuts.
5
Vulcanize and demold
At 23 °C, demolding is possible after approximately 50 minutes; complete curing takes 24 hours. Allow a 24-hour "maturation phase" before the first casting for maximum strength.

Important Notes

Avoid crosslinking inhibitors
Additive systems like MF-Soft 00 are sensitive to sulfur, amine, tin, and phosphorus compounds—especially latex gloves, modeling clay, adhesive tapes, and some paints. If in doubt, make a small test cast before use.
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 Safety Data Sheet (SDS) before opening.
Available containers
1 kg + 1 kg, 5 kg + 5 kg, 25 kg + 25 kg. Other container sizes available on request.
Compatibility
Compatible with polyurethane, epoxy, and polyester casting resins. For aggressive resins, apply a release agent to protect the mold.

Recommended accessories

SILISIL white petroleum jelly release paste
Universal release agent for polyester, epoxy, and polyurethane casts — protects the silicone mold from aggressive resins and extends mold service life.

SILISIL Delayer PA
Retarder for addition-curing silicones — extends pot life and setting time for more complex multi-part builds and relaxed processing.

SILISIL Silicone Remover
Cleaning agent for silicone residues on tools, models, and work surfaces — gentle and effective.

Frequently asked questions about SILISIL RTV MF-Soft 00

Practical application and design questions — answered by SILITECH.

SILISIL RTV MF-Soft 00 is a 2K addition silicone (Shore A 0, translucent) for special effects, film technology, and related applications. Ultra-soft silicone Shore A 0 — skin simulation and FX applications

At 23 °C, the pot life is approximately 5–7 minutes and the demolding time approximately 50 minutes. Complete curing is achieved after 24 hours. Lower temperatures extend, higher temperatures shorten these times.

As an addition system, SILISIL RTV MF-Soft 00 is sensitive to crosslinking inhibitors: sulfur, amine, tin, and phosphorus compounds can locally halt vulcanization. Avoid latex gloves, sulfur-containing modeling clays, some adhesive tapes, and PVC plasticizers in the immediate vicinity of the mold. If in doubt, make a small test cast.

SILISIL RTV MF-Soft 00 is mixed in a 1:1 ratio by weight (base to catalyst), with a maximum tolerance of ±5%. Homogenize both components separately before mixing, then thoroughly incorporate them – including the container walls and bottom. Brief vacuum degassing of the mixture is recommended for non-porous molds.

SILISIL RTV MF-Soft 00 achieves a Shore A hardness of 0 (ASTM D 2240), a tensile strength of >1.1 N/mm² (ASTM D 412), an elongation at break of approximately 550% and a tensile strength of 5 N/mm (ASTM D 624).
