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
#Good flowability, with low viscosity
#Long Shelf life and library life
#Skin safe & medical grade
#Easy processing due to RTV properties.
#Adjustable working time and curing time
What are the Applications of RTV-2 platinum cured silicone rubber
Making silicone products, like silicone insoles, silicone gel, ect. and prosthetics arms, prosthetics hands, prosthetics foot, prosthetics legs, ect. and silicone mask, skin, ect. sex dolls, sex toys, ect.
Processing and Instructions of Addition Cure Silicones
1. Mixing the two components
According the mixing ration 10:1 or 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.
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)
The curing may be slowed down at lower temperature or accelerated by applying heat.
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.
