    Product description

    Silicone Condensation 20 (Medium Hard)

    Description 

    This silicone has a good fluidity and gives great detail while still remaining strong.The silicone Condensation 20  A + B is a 2-component (poly-condensation curing) castable molding silicone which cures at room temperature. Silicone C 20 -A + B are excellently suited for the casting of eg cement, plaster, wax, soap, and many other casting materials.

    Note: Pot life and de-mould time are highly dependent on the mixing ratio and Humidity! By adding more than 2% silicone B (hardener) or at high humidity, the pot life and de-mould time are shorter.

    Processing 
    The silicone C 20 - A + B can easily be mixed by hand or by machine. Mix the A and B component carefully and in the indicated ratio (preferably 2%, you can add between 1.5-3% B comp)

    Example: To 1 kg of A-Comp add preferably 20 grams of B-component. You can vary between 15 grams (1.5%) up to 30 grams (3%). Less or more will inhibit cure or alter the final properties of the rubber.

    At 1.5%, the silicone will take longer to harden giving air bubbles more time to escape. With 3% B component the silicone will cure considerably faster. Process the mixture in the pot life and never take more than you can handle within pot-life. Only de-mould after a complete cure.

    If you wish to make a mold by using a brush or spatula you need to add a 3rd component (0.6% -2% Thixo C). Typically 1% will do the trick. Thixo C thickens the mixture and makes it possible to set up the silicone agains vertical surfaces. Please be aware that the mold in this case must be provided with a support cap. This support cap may consist of gypsum bandages or epoxy support cover or acrylic resin with glass fibre fabric.

    Durability
    Provided that the silicone is kept in a sealed package and stored cool and frost-free, the shelf life is at least 1 year.

    Safety
    If you frequently work with the silicone is recommended to wear during processing gloves and properly ventilate the area. For safety instructions, see always the safety data sheet.

      Super fijn om mee te werken!
      Makkelijk aan te maken en na uit harden is het een mooie stevige siliconen maar die zich makkelijk laat ontmallen van het moeder product, met daarbij elk klein detail behouden.
      Kortom een aanrader!
