Description
|
Latex
False Face Compound is a one part pourable liquid that cures
to a high strength flexible casting rubber when poured into
a dry, unsealed gypsum mold. Latex False Face Compound has
been designed to construct flexible hollow parts for such
uses as novelty masks, flexible sculpture and animatronic
applications. A dipping technique may be utilized to create
latex molds faster than by brushing.

Model
Preparation
|
This product must be cast into a dry, unsealed,
porous plaster mold to permit proper curing. The master/model
must be made of dry, unsealed, porous plaster for proper rubber
buildup and curing when dipping is employed to create a latex
blanket mold. The suitability of other porous materials must
be determined by test results.

Casting
Produce
|
Latex
False Face Compound must be shaken or stirred before use. Pour
into a dry, unsealed gypsum mold. If the mold contains complex
undercuts or deep details, tilting or lightly vibrating the
mold may be helpful in eliminating bubbles. The excess material
may be immediately poured into the container for a thin skin
or allowed to stand longer for a thicker skin. A standing time
of 15 minutes yields a thickness of about 3/32 inches in a No.
1 Pottery Plaster mold.
Denser plasters cause the level of thickness
to build slower because they are not as absorbent. The material
should be allowed to dry in the mold for 24 hours at room
temperature. Higher temperatures will accelerate drying time. |
Using
the Casting
|
Lightly dusting the inside of the casting
with talc will stop the dry rubber from sticking to itself.
Avoid exposing the casting to oils, grease, solvents and direct
sunlight.
Thickener for Platinum Systems, is obtainable to utilize with
Platinum Silicone RTV's. |
Making
the Mold Using the Dipping Technique
|
Begin
with a bucket of False Face Compound. Dip the plaster model
into the latex. Extract and fix bubbles by rotating the model
or using a brush. Dip the model in again and suspend it in
the latex for 45 to 60 minutes. Remove and stand the model
upright. Close the False Face container securely.
Allow the rubber
to dry on the model for 2 or 3 days. At this time, a mother
mold can be constructed. Remove the mold from the model and
permit the latex to dry for an additional 2 or 3 days before
casting.
The process
does have limitations. The model must have a basic pyramidal
shape to allow seamless mold. The model must be made of dry
pottery plaster or some other unsealed plaster. The total
curing time may take numerous days, but the labor savings
is tremendous in comparison with brushing on multiple layers. |
Safety
|
Latex
60 contains ammonia, which is an alkaline dispersion and may
cause burns of skin and eyes. Allow adequate ventilation.
Avoid contact with skin and eyes. If contact occurs, flush
eyes with water for 15 minutes and call a physician. Use soap
and water to remove from clothes and skin.
|
Cleanup
|
Remove
wet latex with soap and water. Waterless hand cleaner may
be used to soften dried latex.
|
Storage
|
Store
between 50°F - 70°F. Exposure to temperatures below
40ºF or above 80°F may damage latex and produce irreversible
coagulation. DO NOT ALLOW TO FREEZE. Storage life is at least
three months from date of shipment. |
