Two-component addition type silicone rubber Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to rubber elastomer . The polymerization can be accelerated by heat. The silicone components are delivered as liquids,which once mixed and cured into a transparent, elastic and resistant material. Polymerization occurs without formation of heat.
Characteristics of Platinum cure liquid silicone rubberConvenient to operate because the RTV propertyEasy to mix due to the low viscosity (7000~9000Cps) High duplication because of high tear and tensile strengthLong shelf life with low shrinkageCan be accelerated for rapid cureApplication of Platinum cure liquid silicone rubber:1.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 coating.
Instructions for Platinum cure medical grade liquid silicone for shoe insole1. 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.Note: It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mix to completely expand and then collapse. After a further 1-2 mins under vacuum, the mix should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture. So a suitably large container should be chosen.
Storage of Platinum cure medical grade liquid silicone for shoe insoleWhen the platinum RTV-2 Silicone Rubber is stored at or below 30 ° C (85° F) in the original unopened containers, RTVsilicone base and CA11curing agent have a usable life of
12 months from the date of production.
