What is RTV-2 platinum cured liquid silicone rubber
RTV2 platinum cured liquid silicone rubber is a two-part, high-performance elastomer that is used for mold making, casting, and other industrial applications. It is called "platinum cured" because it uses a platinum catalyst to initiate the curing process, which results in a higher quality and more durable end product.
What are the Advantages of RTV-2 platinum cured 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.
#Easy Release: RTV2 platinum cure silicone rubber has excellent release properties, which means that the mold or casting can be easily removed from the mold without causing damage to the final product.
#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.

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 by at least 6-7mm
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:
Apply a release agent, Although not usually necessary, a release agent will make demolding easier when casting into most surfaces.
