MC Silicone MCPLA-L25 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.

1. Easy Curing: polymerizes at room temperature (23C).
2.Fast mixing (1:1) and easy processing due to the low viscosity
3. Long shelf life with low shrinkage (0.1%)
4. High tear and tensile strength
5. Odor-free, eco-friendly, For Food Molds, Life casting
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.
Rocessing and Instructions of Addition Cured Liquid Silicones Rubber
The ideal working temperature is around a constant 25°C. Best results can be obtained at constant temperatures between 21°C and 26°C, in a clean, dry, dust-free environment. Avoid working in high humidity.
Measure product in accordance with your intended use. Prepare 1 part A to 1 part B by weight and pour into a clean, smooth-sided container large enough to hold all the liquid and allow room for mixing.
The material must be mixed thoroughly for at least 5 minutes. make sure to scrape the container sides, bottom, and corners as you mix. Be careful not to whip excessive air into the mixture.
Prepare a container(not silicone material),add the item and keep them face up.
Pour the mixed silicone onto the container and distribute evenly to cover the top of the item by at least 6-7mm
Adjust the position and then let it cure, the bubbles will melt gradually.
Pull the item out of the mold
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 -L 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.
