SMITHS DEADENER 

Smiths Prosthetic Deadener is the original and best for creating super soft gel appliances. By varying the ratio of deadener added to Platsil Gel 10 A&B combined you can vary the softness.
A basic rule of thumb would be:
- Silicone mask add 50% Deadener to a mix of A&B. This would be a 1:1:1 mix
- Animatronic skin add 100% Deadener to a mix of A&B
- Prosthetic appliance add 180% – 200% Deadener to a mix of A&B

When you create a gel the silicone no longer has a solid surface and the material becomes tacky to the touch. In order to create a dry workable skin on the gel you must encapsulate the gel. This can be done with a thin layer of Platsil Gel 10 silicone stippled or sprayed in to the mold first or with a bald cap plastic such as Syncap.
