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
#Very stretchy
#Odorless, Eco-friendly
#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.
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.
Storage and shelf life
