Food Grade Platinum Liquid Silicone Rubber RTV2 For Candy/Chocolate/Cake Molds
Product description
MC Silicone MCPLA-L15 is a two-component elastomeric material consisting of Silicone Base, which when mixed with Curing Agent,cures to an elastic and resistant material at room temperature by an addition reaction. The curing can be heat accelerated. A range of materials can be cast into the cured silicone mold.
Good flowablility
High tear and tensile strenght
Flexible and dimensional stability
Easy to de-air
Long shelf life with low shrinkage
Applications
Molding applications requiring low shrinkage. Food grade molds for cake, chocolate, candy, fondant, and other resin crafts, plaster, cement art decorations, etc.

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.

Storage and shelf life
MC Silicone MCPLA Series should be used within 12 months from the
manufacturing date. Beyond this date, MC silicone no longer
guarantees the products confirms with the sales Specification. In
order to preserve best properties it is recommended to follow
strictly the following guild lines:
Store the original packing tightly sealed and at a temperature
below 30 degree Celsius.
Use the product as soon as the packaging has been opened.
