Product Description

Product Description

MCPLA-L Series Platinum-cure liquid silicone rubber also known as addition-cure silicone mold rubber.  It is called "platinum cured" because it uses a platinum catalyst to initiate the curing process. After mixing the two components liquid, RTV-2 platinum silicone rubber will cure into a translucent, elastic and resistant elastomer at room temperature,platinum silicone exhibit the lowest long-term shrinkage and have long library life, which are good for making molds for casting a variety of materials, like polyurethanes, epoxy resin, plaster, concrete,candle molds.

Features

Features of platinum silicone rubber for food molds:

1. Easy Curing: polymerizes at room temperature (23C). 
2. Fast mixing (1:1) and easy processing due to the low viscosity(7000~9000) 
3. Long Library life with low shrinkage (0.1%)
4. High tear and tensile strength, high duplication times 
5. Odor-free, eco-friendly, For Food Molds, Life casting 

Applications

1.RTV2 platinum cure silicone rubber is commonly used for making molds for industrial parts,various materials such as resins, plaster, and concrete, decorative objects.
 
2.Food and Confectionery: RTV2 platinum cure silicone rubber is used in the food and confectionery industry for creating molds for chocolates, candies, and other food items. 
 
3.Special Effects: RTV2 platinum cure silicone rubber is used in the film and entertainment industry for creating special effects and prosthetics.

Instruction

Processing and Instructions of Addition Cure Silicone Rubber

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.

Shelf Life and Storage

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 silicone for some minutes.
