What is MCPLA-L20A/B RTV-2 platinum cured silicone rubber

MCPLA-L25A/B 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,The silicone components are delivered as liquids, which once mixed and cured transform into elastic and resistant material.

What are the Applications of MCPLA-L20A/B RTV-2 platinum cured silicone rubber

#Life casting, Prosthesis Hands, ect.

#Molding applications requiring low shrinkage e.g., jewelry, automotive,

#plaster, cement, cake decorations,candle, soap etc.

What are the Advantages of MCPLA-L20A/B RTV-2 platinum cured silicone rubber

#Easy to Operate : Due to the Room Temperature Cured feature and Low Viscosity, It's easy to use platinum liquid silicone rubber for your DIY Projects at home. No need for vacuum Pumping .

#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.

Processing and Instructions of Addition Cure Silicones

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:

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 RTV-2 platinum cured 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.

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.

Q4: Is platinum silicone food safe?

yes! It's safe to contact Food and skin, which is suitable for making food molds and making Prosthetics .
