Product Description

SILISIL RTV MD-Gel is a room temperature vulcanizing 2-component silicone of the MD — Medical (Dental, Podiatry, Skin Contact)series (Addition (Platinum), RTV-2) — Ultra-soft gel silicone (Shore Gel) for medical and dental applications with the lowest consistency.

The mixture is prepared in a 1:1 ratio by weight . Pot life at 23 °C is approximately 10 minutes; demolding is possible after approximately [timeframe missing] (gel consistency); complete curing occurs after 24 hours. Temperature resistant from -40 °C to +200 °C.

Key property

Gel consistency for medical soft applications — lowest hardness in the range, mixing ratio 1:1, suitable for skin contact after appropriate certification testing.

What distinguishes SILISIL RTV MD-Gel

Gel consistency — softer than Shore A 0
Very low viscosity 1,000 mPa·s
Low mixed viscosity — flows into finest structures without air entrapment, vacuum degassing optional.
Skin-friendly for lifecasting
Tested for direct skin contact — suitable for body casts of face, hands and torso.
Pot life 10 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.
Vulcanization at room temperature
Curing at room temperature — no oven, no UV lamp, no special equipment required.

What is SILISIL RTV MD-Gel used for?

Dental models and bite registrations
Ultra-soft gel for bite impressions, model fixation and soft-touch components in dentistry and dental technology.
Skin simulation and training models
Anatomical training models for medical and nursing education — lifelike soft tissue imitation.
Miracle simulator and surgical exercise
Realistic simulation for surgical training, emergency medicine and first aid training.
Soft-touch pads for medical devices
Cushioning and contact surfaces for patient supports, operating tables and ergonomic medical devices.
Acoustic and vibration damping
Ultra-soft damping in precision devices — audiometry, diagnostic equipment, vibration decoupling.
Forensics and anatomical replicas
Lost wax casting and detailed reproductions with the highest soft consistency for research and teaching.

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 approx. (gel consistency), 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-Gel

Practical application and design questions — answered by SILITECH.

SILISIL RTV MD-Gel is a 2K silicone from the MD — Medical (Dental, Podiatry, Skin Contact) series (Shore A Gel, Translucent). This ultra-soft gel silicone (Shore Gel) is designed for medical and dental applications with the lowest possible consistency — suitable for dental models, bite registrations, and related applications.

At 23 °C, the pot life is approximately 10 minutes and the demolding time is approximately [timeframe needed] (gel consistency). Complete curing occurs after 24 hours.

SILISIL RTV MD-Gel is an addition (platinum) system. Addition system (platinum) — sensitive to sulfur, amine, tin, and phosphorus compounds. Avoid contact with latex gloves and PVC plasticizers.

SILISIL RTV MD-Gel 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-Gel achieves a Shore A hardness of gel (ASTM D 2240), a tensile strength of (see TDS) N/mm² (ASTM D 412), an elongation at break of approx. (see TDS) % and a tear resistance of (see TDS) N/mm (ASTM D 624).
