SILISIL RTV MD-Soft 10
SILISIL RTV MD-Soft 10
SILISIL ·

SILISIL RTV MD-Soft 10 is a room temperature vulcanizing 2-component silicone of the MD — Medical (Dental, Podiatry, Skin Contact)series (Addition (Platinum), Soft variant, RTV-2) — Soft silicone Shore A 10 for medical soft-touch applications without direct skin contact.

The mixture is prepared in a 1:1 ratio by weight . Pot life at 23 °C is approximately 7 minutes, demolding is possible after approximately 30 minutes, and complete curing takes 24 hours. Temperature resistant from -40 °C to +200 °C.

Key property

Soft variant Shore A 10 for medical and industrial soft-touch applications without direct skin contact — same mechanics as MD-Skin 10, without skin contact certificate.

What distinguishes SILISIL RTV MD-Soft 10

Final hardness Shore A 10 — very soft
High elongation at break 600%
High elasticity — reliable demolding of complex geometries without damaging the mold or the original.
Tear resistance 11 N/mm
Solid tear resistance — sufficient for medium series with standard materials.
Low viscosity 4'500 mPa·s
Low mixed viscosity — flows into finest structures without air entrapment, vacuum degassing optional.
Pot life 7 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 10 used for?

Industrial soft-touch components
Keyboard membranes, sensor pads, housing padding and soft controls in the medical device industry.
Medical device components
Soft components without direct skin contact — inner padding, cushions, vibration damping in medical devices.
Training and teaching models
Anatomical models for nursing and medical training with soft tactile sensation — without requirements for skin contact certificates.
Industrial acoustic damping
Vibration and sound damping in precision instruments and measuring equipment — elongation at break 600% absorbs mechanical shocks.
Soft bindings in robotics
Gripper and support components for robots that handle sensitive workpieces.
Mock-up and design models
Soft-touch prototypes for medical device development and industrial design — lifelike feel without medical certification.

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 30 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.

Recommended accessories

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

Frequently asked questions about SILISIL RTV MD-Soft 10

Practical application and design questions — answered by SILITECH.

SILISIL RTV MD-Soft 10 is a 2K silicone from the MD — Medical (dental, podiatry, skin contact) series (Shore A 10, translucent). This Shore A 10 soft silicone is designed for medical soft-touch applications without direct skin contact and is suitable for industrial soft-touch components and related applications.

At 23 °C, the pot life is approximately 7 minutes and the demolding time approximately 30 minutes. Complete curing takes 24 hours.

SILISIL RTV MD-Soft 10 is an addition (platinum), soft variant system. This addition system (platinum) is sensitive to sulfur, amine, tin, and phosphorus compounds. Avoid contact with latex gloves and PVC plasticizers.

SILISIL RTV MD-Soft 10 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 10 achieves a Shore A hardness of 10 (ASTM D 2240), a tensile strength of 3.5 N/mm² (ASTM D 412), an elongation at break of approximately 600% and a tensile strength of 11 N/mm (ASTM D 624).
