    Two Parts RTV Polyaddition Platinum Cure Silicone Rubber For Resin Arts And Crafts

    Transparent Two Parts RTV Polyaddition Platinum Cure Silicone Rubber For Rapid Prototype Casting


    Product description

    Two-component addition type silicone rubber , liquid silicone rubber is a two component elastomer cross-linking at room temperature. 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.


    Features

    High Transparency

    High tear and tensile strength

    Long shelf life with low shrinkage

    Fast mixing (10:1)

    Easy processing due to the low viscosity

    Applications

    Label manufacturing, Molding applications requiring low shrinkage e.g. toys, jewelry, automotive, rapid prototyping etc.

    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: in general contact with certain materials can inhibit the cross linking of RTV.
    Natural rubbers vulcanized with sulfur
    RTV silicone compound catalyzed with metal salts, e.g. Tin compounds PVC stabilized with tin salts and additives
    Epoxy catalyzed with amines
    Certain organic solvents, e.g. Ketones, alcohols, etc.
    Packaging
    20kg per drum, 200kg per drum


    Storage and shelf life
    MC Silicone MCPLA -H Series should be used within 12 months from the manufacturing date. Beyond this date, MC silicone no longer guarantees the products confirms with the sales Specification. In order to preserve best properties it is recommended to follow strictly the following guild lines:
    Store the original packing tightly sealed and at a temperature below 30 degree Celsius.
    Use the product as soon as the packaging has been opened.
