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.

 

What are the Applications of RTV-2 platinum cured 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 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.

 

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:

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 stillgummy?
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.
Q3: Why the platinum silicone rubber do not cure?
Platinum-cure silicone rubbers are critically sensitive to some materials and will not cure under any circumstances when exposed. like the materials below:
#Natural rubbers vulcanized with sulfur
#RTV elastomer is catalyzed with metal salts, e. G. Tin compounds
#Epoxy catalyzed with amines
#Certain organic solvents, such as Ketones, alcohols, etc.
