    Product details Application Usage / application examples Notes

    Field of application

    • For use indoors and outdoors
    • Casting of high-value original pieces with accurate detail
    • Production of solid and main moulds
    • Forming with strong undercuts

    Properties

    • High reproduction accuracy and detail reproduction
    • Excellent resilience
    • Very good elasticity and tear resistance
    • Good flow properties
    • Easy demoulding
    • Preparation
      • Substrate requirements

        The substrate must be clean, dust-free and dry.

    • Application
      • Application temperature: min. 5 °C max. 30 °C
      • Drying time: can be worked over after 20 h
      • Application requirements

        Temperature of the material, air and substrate: from min. +5 °C to max. +30 °C

      • Pour or apply by brush

        Reaction time approx. 20 hours

    • Application instructions

      • The addition of up to 1% by mass of Thickening Additive AFM (0738) can increase the viscosity until stability is reached.

        To ensure that the vulcanised material is completely free of bubbles, degas the silicone/hardener mixture in a vacuum prior to use (max. 5 minutes at 10-20 mbar).

        Pourable resins, such as polyesters and polyurethanes, limit the ability to take a large number of impressions due to their aggressive nature.

        When making impression of critical substrates, e.g. materials that are porous, silicate-based or moisture-absorbing, use a silicone-free releasing agent (e.g. wallpaper paste).

        When creating supporting moulds, a suitable release agent must be applied to the outer skin of the silicone mould, e.g. Framework Paste (1121).

    • Working tools / cleaning

      • Paintbrush, spatula, stirrer

      • Clean tools immediately after use with thinner and brush cleaner.

        Pull off any cured residue.

    • Storage / shelf life
      • Store frost-free and cool / protect for moisture / close containers
      • Shelf-life 12 months

      • If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 12 months.

    • Usage
      • 1.2 kg / l void

      • Approx. 1.2 kg/m²/mm layer thickness

    • General information

      • Current regulations and legal requirements must be taken into account and deviations from these must be agreed separately.

        The relevant test certificates must be observed when planning and carrying out work.

    • Disposal instructions
