Translucent Odorless Soft Skin Safe Platinum Silicone For Making
Candle Soap Molds
Product description
Two-component addition type silicone rubber Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone
system that cures (RTV) to a flexible rubber. The polymerization can be accelerated by heat. The silicone
components are delivered as liquids, which once mixed and cured
transform into a transparent, elastic and resistant material.
Polymerization occurs without formation of heat.
Features
Good flowability
Very stretchy
Odorless
Long Shelf life
Skin safe & medical grade
Easy processing - mixing ratio 1 : 1
Adjustable working time and curing time
Applications
Liquid platinum cure silicone rubber for soft fake pregnant belly
has 2 main applications:
First: making many kinds of molds:
Making molds for:
Low melt metals (mold life can be short), Cement, Concert,concrete
stones, wax molds, PU molds, resin molds, gypsum casting, candle
molding, chocolate , candy and any other food product mold making,
prototyping etc.
Making molds for food grade products: chocolate molds, cake molds,
sugar molds,ect.
Making molds for life casting: real hand molds, real feet
molds,ect.
Second: make silicone products, like silicone insoles, silicone
gel, ect. and prosthetics arms, prosthetics hands, prosthetics
foot, prosthetics legs, ect. and making molds for candle and soap,
ect.

Processing and Instructions of Addition Cure Silicones
1. Mixing the two components
According the mixing ration 10:1 or 1:1 weighting A and B, the two
components may be thoroughly mixed either by hand or using a
low-speed electric to minimize the degassing of bubbles and to
avoid any temperature increase. Note: It is also possible to use a
special mixing and dispensing machine for the silicone components,
further information is available upon request.
2. Moulding
The mixture should be degassed preferably at 30 to 50 mbar to
eliminate any entrapped air. If a dispensing machine is used, the
two components are degassed separately prior to mixing. The
silicone mixture expands to 3-4 times of its initial volume and
bubbles rise to the surface. The bubbles progressively disappear
and the mixture returns to its initial volume after 5 to 10
minutes. Wait a few minutes to complete the degassing and then
flash the vacuum. The silicone is ready for pouring, either by
gravity or under low pressure.
Note: Flashing the vacuum once or twice accelerates the degassing.
It is recommended to use a container with a high diameter/height
ratio (3 to 4 times of the initial volume)
3. Polymerisation
The curing may be slowed down at lower temperature or accelerated
by applying heat.
Note:
Contamination from sulfur (e.g., sulfur-based clay), amines, tin
compounds, cured polyester resin, some paints and some silicone
rubbers may inhibit surface cure of platinum-cured rubbers.
Apply a release agent, Although not usually necessary, a release
agent will make demolding easier when casting into most surfaces.
