1:1 Translucent RTV2 Liquid Silicone Rubber Platinum cured silicone rubber Technical Properties
Two-component addition type silicone rubber Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a Shore A20 rubber. The polymerization can be accelerated by heat. The silicone components are delivered as liquids, which once mixed and cured transform into a transparent, elastic and resistant material. Polymerization occurs without formation of heat.
Applications
1.A range of materials can be cast into the cured silicone mold: Polyurethane, Epoxy resin and other reactive resins Small pieces of cement,plaster,gypsum,concrete products. Food like chocolate,fondants,desserts Wax,candle,soap; Low melt metal
2.Life casting,casting body parts,prosthetics.
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. Packaging 20kg per drum, 200kg per drum
