Platinum cure Skin Safe for SFX/silicone mask liquid RTV2 Silicone
Rubber
Description of RTV Silicone for Life CastingRTV silicone rubber is a two component 1:1 elastomeric
cross-linking at room temperature. The polymerization can be
accelerated by heat (max. 150 C). The silicone components are
delivered as liquids, which once mixed and cured transform into a
elastic and resistant material. Polymerization occurs without
formation of heat.
Advantages of RTV Silicone for Life Casting
Custom color
Convenient to operate with the RTV propertyEasy to mix due to the low viscosity (7000~9000Cps)High duplication with high tear and tensile strengthLong shelf life with low shrinkageExcellent chemical resistanceCan be accelerated for rapid cureApplications of RTV Silicone for Life Casting1.A range of materials can be cast into the cured silicone mold:polyurethane and other reactive resinsSmall pieces of cement,plaster,concrete products.Food like chocolate,fondantsWax,candle,soap;Low melt metal2.casting body parts,shoe insole,cloth label,texture coatingProcessing and Instructions of Addition Cure Silicone1. Mixing the two componentsAccording 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. MouldingThe 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. PolymerisationThe curing may be slowed down at lower temperature or accelerated
by applying heat.Note:1.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.2.Apply a release agent, Although not usually necessary, a release
agent will make demolding easier when casting into most surfaces.Storage of RTV Silicone for Life CastingWhen the silicone rubber is stored at or below 25 degree Celsius in the original unopened containers, Silicone Base and Curing agent
have a usable life of 12 months from the date of production. After
12 months' stockpiles, please use tool to stir the Part A silicone
for some minutes, then the silicone can be use again, no influence
for other performance.1.Store the original packing tightly sealed and at a temperature
below 25 degree Celsius.Use the product as soon as the packaging has been opened.2.Close the lid tightly after taking out the proper amount of liquid
silicone rubber.Packing of RTV Silicone for Life Casting20kg per drum, 200kg per drum20kg/drum;480kg/pallet or 640kg/pallet.Certificate and R&D:
