    Product description

    Separate B 5 - B component for Silicone Condensation 5, 20 and 35 universal

    This hardener works on all condensation silicones.

    For standard use, the condensation B 5% catalyst is recommended.

    Processing

    The silicone Condensation 20, you can easily mix by hand or machine. Mix the A and B component carefully and in the specified proportion.

    Condensation B 5 = 5%, so on 100 grams of A you use 5 grams of B 5.

    You can use up to 0.5% less or more harder. If you use less hardener, curing takes longer and air bubbles have more time to escape. Make sure not to use too little hardener, because then the silicone may no longer cure (properly). With more harder the curing will go faster, so that the mold is ready sooner. The disadvantage is that the mold will also age earlier and have more shrinkage bag.

    Process the mixture within the pot life (working time) and never make more than you can process within the pot life. Wait with de-moulding until it has completely hardened.

    Note: Potlife (processing time) and demolding time are highly dependent on the mixing ratio and Humidity! When adding more silicone B (harder) or at higher humidity, the pot life and demolding time become shorter!

    Smearing or brushing

    If you want to spread/brush the silicone on something, you can add Thixo C (0.6%-2%) (usually 1%). Thixo C is a thickener and makes it possible to spatulate the silicone. You should take into account that in this case the mold must be provided with a support cap. This support cap can consist of a plaster cast, an epoxy support cap, or acrylic resin with thickener and glass fabric 

    shelf life
    Provided that the silicone is stored in closed packaging, cool and frost-free, the shelf life is at least 1 year.

    Safety requirements
    Use splash goggles, suitable liquid-tight gloves, an apron and work in a well-ventilated area. See Safety Data Sheet for more information
