Product Description

MC Silicone MCPLA Addition Cure Series is a two component material cures at room temperature to a Shore A 5~55 rubber by an addition reaction. A range of materials can be cast into the cured silicone mold:polyurethane and other reactive resins are the materials typically used. The polymerization can be accelerated by heat.

Features of platinum silicone rubber for food molds:
Convenient to operate because the RTV property
Easy to mix due to the low viscosity (7000~9000Cps)
High duplication because of high tear and tensile strength
Long shelf life with low shrinkage
Can be accelerated for rapid cure

Application of platinum silicone rubber for food molds:
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.casting body parts,shoe insole,cloth label,texture coating.

INSTRUCTION:Processing and Instructions of Addition Cure Silicone
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 platinum silicone rubber for food molds:
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.

Package:
20kg per drum, 200kg per drum
20kg/drum;480kg/pallet or 640kg/pallet.
