PlatSil Gel-10 is a two-part platinum (addition) silicone with Shore A10 hardness, translucent and easy to mix in equal parts. Developed by Polytek, it is a well-established reference in special effects, encapsulated prosthetics and animatronics thanks to its fast cure, exceptional reliability and precise pigmentation capacity for mimicking soft tissue.

What it is used for

PlatSil Gel-10 is designed for applications requiring a soft, translucent silicone with controlled cure. Its Shore A10 hardness makes it especially versatile for both mold making and direct fabrication of prosthetic pieces.

Encapsulated prosthetics for special effects and prosthetic makeup (mixed with Deadener at 180–200 %)
Skins and membranes for animatronics and puppets
Flexible molds for low-relief pieces and complex geometries
Soft props: organs, wounds, synthetic tissues for film and TV
Masks and character pieces requiring natural movement
Reborn babies and hyperrealistic silicone figures
Artistic reproductions imitating flesh or human skin, pigmented with silicone-specific pigments

How to use it

Prepare the surface or mold and make sure it contains no inhibiting materials (latex, sulfur-containing clays, tin silicone, fresh polyester, epoxy). Apply release agent if necessary.
Weigh or measure parts A and B in a 1:1 ratio by volume. Use clean, dry containers.
If you are gelling for encapsulated prosthetics, add Deadener at 180–200 % relative to the total silicone weight and mix until fully homogeneous.
If you want to pigment, add platinum silicone-compatible pigments into part A before mixing with B.
Mix A+B with slow, folding movements for 1–2 minutes to minimise bubble incorporation. Remember that the working time is only 6 minutes.
Pour or apply the material immediately. If you need greater thickness or brush application, use PlatThix to thixotrope the mix before applying.
Allow to cure for 30 minutes at room temperature (25 °C). Higher temperatures accelerate curing; lower temperatures slow it down.
Demold carefully. The piece is ready to work with; if you need more handling time, refer to the use of PlatSil Retarder 71/73 R.

Warning — Platinum silicone inhibition
Addition silicones like PlatSil Gel-10 are sensitive to contamination by inhibitors. Contact with any of the following materials may prevent full or partial cure, leaving the silicone sticky or uncured:

Clays and plasticines containing sulfur (sulphide)
Tin (condensation) silicone — even surface traces
Natural latex
Freshly cast or incompletely cured polyester resins
Epoxy resins
Urethane rubbers
Vinyl and some plasticised plastic materials
Some paints, unsealed metals and contaminated surfaces

Always perform a compatibility test on a small area before working on unknown surfaces. If using plaster or resin molds, seal them properly before contact with the silicone.

Usage tips

Working time control

With only 6 minutes of working time, prior organisation is essential. Have all tools, molds and pigments ready before starting the mix. If you need more time, PlatSil Retarder 71/73 R can extend the working time; do not exceed 3 % of the total mix weight to avoid compromising the cure. Heat accelerates setting: in summer or in warm workshops, work with the components at a controlled temperature.

Encapsulated prosthetics with Deadener

For soft prosthetics that blend into the skin, mix PlatSil Gel-10 with Deadener in the ratio 1A : 1B : 180–200 % D. Gelling increases softness and translucency, mimicking subcutaneous tissue in a very convincing way. Pigment with flocking and silicone pigments in intrinsic layers for realistic colour depth. Always use an encapsulant (Key-cap Plastic or another compatible product) so that the edges of the prosthetic blend seamlessly into the actor's skin.

Pigmentation and translucent finish

The translucent base of PlatSil Gel-10 is a key advantage: it allows layered colour work with depth, just like real skin. Add pigments only to part A before mixing with B, which ensures even dispersion. If you are brushing the silicone onto an encapsulant, use Titanic FX flocking to reproduce the capillary fibres of the skin. Avoid overdoing the pigment, as high concentrations can interfere with curing.

Frequently asked questions

What materials inhibit the cure of platinum silicones?

Platinum silicones like PlatSil Gel-10 do not cure correctly if they come into contact with sulfur (sulfur-containing clays and plasticines), natural latex, tin (condensation) silicone, freshly cast polyester, epoxy, urethane rubbers, vinyl and some paints or unsealed metal surfaces. The usual result is that the silicone remains sticky or uncured in the contact area. Always perform a prior test on unknown surfaces.

Can I use tin silicone molds to cast this platinum silicone?

No. Platinum silicone does not cure against tin (condensation) silicone: tin compounds inhibit the platinum catalyst. If you need a flexible mold to reproduce pieces in PlatSil Gel-10, use molds also made from platinum silicone or from compatible materials that have been properly sealed.

How much Deadener should I add for encapsulated prosthetics?

For encapsulated prosthetic applications, the standard ratio is 1A : 1B : 180–200 % Deadener relative to the total silicone weight. This amount gels the mix and achieves the softness and translucency needed to mimic soft tissue. Adjust the amount according to the desired softness: more Deadener produces a softer, more gelatinous piece.

How can I extend the working time if 6 minutes is not enough?

You can add PlatSil Retarder 71/73 R at a maximum ratio of 3 % of the total mix weight. Exceeding that percentage may inhibit or compromise the cure. Working with the components at a lower temperature (below 20 °C) also helps, as the cold slows down the reaction.

Is it necessary to use an encapsulant for silicone prosthetics?

Yes, it is highly recommended. The encapsulant (such as Key-cap Plastic) creates an outer film that allows the edges of the prosthetic to be blended into the skin, making the transition invisible. Without an encapsulant, the silicone edges remain visible and the prosthetic does not adhere correctly for the makeup process.

Can I pigment this silicone with any colorant?

No. You should only use pigments specifically formulated for platinum silicones. Standard colorants, acrylic paints or oil pigments may inhibit the cure or fail to disperse correctly. Titanic FX flocking is a widely used option in prosthetic makeup for its ability to reproduce the texture and depth of skin.

How do I get a thicker silicone for brush application?

Add PlatThix (thixotropic agent for platinum silicones) to the mix before applying. PlatThix increases viscosity without altering the cure time, allowing you to brush layers onto molds or encapsulants without the material dripping.

At what temperature can the cure be accelerated?

The cure of PlatSil Gel-10 can be accelerated by applying moderate heat (between 40–60 °C in an oven or with a heat gun at a safe distance). At 25 °C the cure time is 30 minutes. Bear in mind that at very high temperatures the reaction may be too fast and hinder the work. Cold, on the contrary, slows down curing and can be used to gain handling time.
