Softener for PlatSil® Gels: silicone that feels and moves like skin
Smith's Theatrical Prosthetic Deadener from Polytek Development Corp. is an additive for the PlatSil® Gel range, widely used in special effects and prosthetic appliances. Adding Deadener to Part A removes the springy, synthetic feel of ordinary silicone. The gel becomes softer, recovers more slowly and takes on the look, feel and movement of living tissue. You control how soft the result is through the amount of Deadener you add.
Key benefits
- Skin-like result: takes away the snappy silicone response, so appliances stretch and recover slowly like human tissue.
- No leaching: unlike silicone fluid, Deadener is bound into the network and does not seep out of the cured part. Bonding and use stay much easier as a result.
- Infinitely adjustable: from Shore A 17 down to Shore OOO 5, depending on the PlatSil Gel and the dosage.
- No change to the A:B mix ratio: PlatSil Gels are still mixed 1:1, Deadener is added as a third component.
- Not classified as hazardous under GHS and not regulated for transport.
⚠️ More Deadener means a tacky surface
Above the recommended dosage the cured gel becomes tacky and can no longer be painted. Deadened gels are therefore almost always encapsulated: with a thin layer of PlatSil Gel without Deadener that you stipple or spray into the mould first, or with a cap plastic. Talcum powder can reduce the tackiness further.
- ✓ Polytek advises not to add Deadener to PlatSil Gel-OO20 and PlatSil Gel-OO30.
- ✓ The safety data sheet states use for industrial and professional applications. We make no skin safety claim for the Deadener itself. If you make a product for skin contact, test the cured end product.
Typical applications
- ✓ Gel-filled prosthetic appliances for film, theatre and television
- ✓ Silicone masks and age make-up
- ✓ Animatronic skins and creature effects
- ✓ Wounds, scars and other SFX effects
- ✓ Lifelike simulation models and dolls

Processing
- Read the safety data sheet and the Technical Bulletin before use.
- Weigh out the required amount of Deadener, calculated on the total weight of A + B.
- Mix the Deadener thoroughly into Part A until the mixture is completely homogeneous.
- Add Part B and mix as specified for the PlatSil Gel you are using.
- Encapsulate the gel: first apply a thin layer of PlatSil Gel without Deadener or a cap plastic in the mould, then pour the deadened gel.
- Always carry out a test cure first to determine the right dosage for your application.
Points to note
- ✓ Always add Deadener to Part A before mixing in Part B.
- ✓ PlatSil Gels are platinum silicones. Sulphur-containing clay, latex, uncured polyurethane and epoxy, tin silicones and many SLA 3D prints can inhibit the cure.
- ✓ Wear nitrile or butyl gloves and safety glasses and work in a ventilated area.
- ✓ Store in the closed original container at 15 to 32 °C. Polytek recommends using the product within six months.
