    How to use

    When designing joints using DOWSIL™ 796 neutral silicone, the minimum joint width should be 6mm. For joints between 6 and 12 mm wide, a sealing depth of 6 mm is required. For joints wider than 12 mm, a width to depth ratio of 2:1 should be used.

    Substrate preparation

    Make sure that the surfaces to be sealed are clean, dry, sound and free from dust. Clean all joints of release agents, water repellents, cement laitance, dirt, old sealants and other contaminants.

    Non-porous surfaces should be cleaned and degreased with a suitable solvent such as DOWSIL™ R-40 Universal Cleaner.

    Porous substrates should be cleaned mechanically using a steel brush, grinding wheel or similar means.

    Masking / Protection

    Areas adjacent to joints should be masked with tape to prevent contamination of the substrate and ensure a clean line of sealant. The masking tape must be removed immediately after applying the silicone.


    For PVC-U and most common construction substrates, no primer is required. However, it is always recommended to test before use.

    Machining / Finishing

    The joint should be machined within 5 minutes of application to ensure good contact between the sealant and the substrate.


    Excess sealant can be removed in the uncured state using DOWSIL™ R-40 Universal Cleaner. If the sealant is incorrectly applied to porous substrates, it should be allowed to cure completely and then removed mechanically.


    DOWSIL™ 796 Neutral Silicone is not recommended for structural glazing. Do not use it on bituminous substrates, natural rubber, chloroprene or EPDM based substrates or on building materials that may bleed oils, plasticizers or solvents.

    Special tests must be carried out on sensitive substrates .
    DOWSIL™ 796 neutral silicone is not suitable for food contact.
    It is recommended that DOWSIL™ 796 Neutral Silicone not be applied to surfaces that are
    below 5°C (41°F).

    This product is not tested or claimed to be suitable for medical or pharmaceutical use.
