    Description 

    The silicone Condensation DC 3481 with the catalyst 3081 R is a professional 2-component (poly-condensation curing) castable molding silicone which cures at room temperature. The silicone has a good fluidity and gives great detail while still remaining strong. Silicone DC 3481 R is excellently suited for the casting of eg cement, plaster, wax, soap, and many other casting materials but also for aggressive resins like poly urethane, epoxy and polyester.

    Note: Pot life and de-mould time are highly dependent on the mixing ratio and Humidity! By adding more than 5% silicone B (hardener) or at high humidity, the pot life and de-mould time are shorter.

    Processing 

    The silicone DC 3481 with catalyst 3081 R can easily be mixed by hand or by machine. Mix the A and B component carefully and in the indicated ratio (preferably 5%, you can add between 4 and 6% B comp)

    Example: To 1 kg of A-Comp add preferably 50 grams of B-component. You can vary between 40 grams (4%) up to 60 grams (6%). Less or more will inhibit cure or alter the final properties of the rubber.

    At 4%, the silicone will take longer to harden giving air bubbles more time to escape. With 6% 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.
