Gord’s Notes:

Smith’s Prosthetic Deadener is an additive designed to work in concert with Platsil Gel-10
(or any platinum silicone) to create a complete theatrical prosthetic design system for the
motion picture industry.

The result of 25 years of research and development, to achieve greater creative freedom
and control over the many physical and visual qualities apparent in living tissue, while
at the same time creating a safe working environment.

Smith’s Prosthetic Deadener added to any platinum cure silicone liquid rubber lowers it’s
shore while, at the same time, eliminating the synthetic movement qualities inherent in all rubbers.

It is a chemically stable prosthetic gel system designed specifically to simulate the qualities of
softness and movement inherent in living tissue.

It is safe to use for both artist and the actor /patient creating a safe working environment on
or off the set.

Neither liquid or cured silicones will shrink or decay over time.

Add, by weight, as much as 250% Smith’s Prosthetic Deadener to mixed Platsil Gel-10
to create any softness of prosthetic gel you need.

Over 30% Smith’s Prosthetic Deadener will result in a not paintable sticky cured gel.
The stick can be eliminated with powder or by a paintable barrier coat of Platsil Gel-10.

Platsil Gel-10 is a perfect barrier coat for painting and creating skins surface tension.

It is therefore not necessary to encapsulate both sides of a prosthetic which means you can
achieve much finer edges that a fully encapsulated prosthetic.

Once a gel is powdered the stick cannot be brought back. If you want to use the stickiness
of the gel, cover the exposed gel with clean plastic.

Any gel can be glued with standard silicone prosthetic adhesives or you can design the sticky
factor into a self-sticking prosthetic or you can use a very thin layer of Platsil Gel-10 to adhere
the prosthetic to the skin.

If Platsil Gel-10 is used as an adhesive it will bond to the prosthetic and peel off with no solvents.

A self-sticking gel or Platsil Gel-10 adhered prosthetic frees the skins to move with none of
the restriction inherent in all glues (medical or latex) resulting in comfort and remarkable
movement qualities.

The prosthetic can be washed in the sink with soap and water ready for another day’s use,
if designed to do so.

Over 250% Smith’s Prosthetic Deadener achieves a super gel (IE: fat). However it results
in an over deadened gel, relative to living tissue. To return elasticity to a super gel, Smith’s
Prosthetic Deadener can be substituted, up to 10%, with Smith’s Prosthetic Gel Additive #1
without effecting the softness of the gel.

The system is designed for intrinsic and or external colouration.

For constant accurate colour control start with SiliClone Human Colouration System for
platinum silicone prosthetics. It is designed and hand manufactured to the highest laboratory
standards for the medical prosthetics industry. Colours are dispensed in graduated syringes
for control of colour formulations.

Flocking can also be used for colour that does not effect the opacity or the translucency of the gel.

Edges can be filled or repaired with tiny amounts of Platsil Gel-10 then matted out with
Smith’s Silicone Matting Powder.

Always vacuum materials for consistent results.

Easy reliable mixing. Platsil Gel 10 is a fast curing rubber. 50/50 mix by weight or by eye.

No de-lamination problems.

Minimize materials wastage by mixing only what you can use within the given working times.

Working time is generally 5 minutes for Platsil Gel-10 but is subject to room temperature and %
of Smith’s Prosthetic Deadener added.

Work slowly and accurately knowing that there will be no evidence of where you stopped
and started.

Smith’s 244 Silicone Fluid can be added, sparingly, to thin Platsil Gel-10 for brushing up
thin membranes.

Work time can be increased by cooling or freezing the materials. I suggest you keep it in the
fridge or in a freezer. Cure time is also accelerated with heat.

Generally no release is necessary except to control the ease of removal from the mould.
For mould releases we suggest Vaseline, Ivory soap, Parafilm wax or what ever works for you.
Always test.

When using a brush first rub Vaseline into the fibers before using it. Clean used brush with
D-Limonene Brush Cleaner. Rinse in 99% alcohol then wash with soap and water.

Do not use rubber glove or rubber sponges. Natural latex rubber will inhibit the cure of the
silicone. Some older Urethanes and Aloe Vera are the only other contaminates we have found
to date. Always test.

Do not use adhesive removers such as Detachol because elements in it will break down a
cured gel. Always test.


If your work space is contaminated with natural rubber this system will not work for you.
It is safe and reliable to use in any other environment.
