what is RTV-2 platinum cured liquid silicone rubber
MCPLA-L15A/B Two-component addition type silicone rubber Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to flexible elastomer. The polymerization can be accelerated by heat. The silicone components are delivered as low viscosity liquids, which once mixed and cured into a translucent, elastic and resistant material.
what are the Advantages of RTV2 platinum cure silicone rubber
#High Tear Strength: RTV2 platinum cure silicone rubber has a high tear strength,
making it ideal for making complex molds that require multiple
demolding cycles.
#Excellent heat resistance:Platinum cured silicone rubber can withstand high temperatures without degrading or losing its properties, making it suitable for use in high-temperature applications such as automotive and aerospace industries.
#Non-Toxic and Skin Safe: RTV2 platinum cure silicone rubber is non-toxic and skin safe, making it safe for use in applications that come into contact with skin or food.
what are the Applications of RTV2 platinum cure silicone rubber
1.RTV2 platinum cure silicone rubber is commonly used for making molds for industrial parts,various materials such as resins, plaster, and concrete, decorative candles, Soap.
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.
Processing and Instructions of Addition Cure Silicones
Step 1
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.
Step 2
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.
Step 3
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.
Step 4
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.
Step 5
Adjust the position and then let it cure, the bubbles will melt
gradually.
Step 6
Pull the item out of the mold
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.

FAQ of RTV2 Platinum Cured Liquid Silicone Rubber
Q1: Why the curing time of platinum silicone varies in environment
with different temperature ?
Platinum (addition) cured silicone rubber,Which with platinum
catalyst and uses heat to transform from liquid to solid rubber.
Therefore, platinum cured silicone rubber is sensitive to
temperature, platinum systems are often cured quickly with heat,
although they can also be formulated to cure at low temperatures
and room temperature.
Q2:why the bottom and sides of platinum silicone molds are still
gummy?
platinum silicone rubber requires accurate and careful mixing. The
material must be mixed thoroughly for at least 3~5 minutes. make
sure to scrape the container sides, bottom, and corners as you mix.
