RTV2 Platinum Silicone Mold Rubber For Ice Cube Mold
Product description Of RTV2 Platinum Silicone Mold Rubber For Ice Cube Mold
Two-component addition type silicone rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a Shore A 0~55 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 Of RTV2 Platinum Silicone Mold Rubber For Ice Cube Mold
Outstanding release properties
Cure can be heat accelerated
High transparent appearance to cut split lines
Very low shrinkage and good dimensional stability
High hardness, but flexible and very tough
Can be used for high temperature casting applications
Applications Of RTV2 Platinum Silicone Mold Rubber For Ice Cube Mold
1. A range of materials can be cast into the cured silicone mold:
polyurethane and other reactive resins
Small pieces of cement,plaster,concrete products.
Food like chocolate,fondants
Wax,candle,soap;
Low melt metal
2. Label manufacturing, toys, jewelry, automotive, rapid
prototyping etc.

Processing and Instructions of Addition Cure Silicones
1. Mixing the two components
According the mixing ration 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:
1. 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.
2. Apply a release agent, Although not usually necessary, a release
agent will make demolding easier when casting into most surfaces.

Storage and shelf life Of RTV2 Platinum Silicone Mold Rubber For Ice Cube Mold
When the silicone rubber is stored at or below 25 degree Celsius in
the original unopened containers, Silicone Base and Curing agent
have a usable life of 12 months from the date of production. After
12 months’ stockpiles, please use tool to stir the Part A silicone
for some minutes, then the silicone can be use again, no influence
for other performance.
1. Store the original packing tightly sealed and at a temperature
below 25 degree Celsius.Use the product as soon as the packaging
has been opened.
2. Close the lid tightly after taking out the proper amount of
liquid silicone rubber.
Use the product as soon as the packaging has been opened.
