    Product properties & Features

    RE is a highly active cross-linking agent, Used in the adhesives made by hydroxyl polyurethane, natural or synthetic rubber,

    It has excellent bonding strength in rubber and cab be used in resin, antioxidant, plasticizing agent, pressure-sensitive etc.

    It can be used as crosslinker instead of BAYER’s Desmodur RE

    RE 1

    Usage

    Two-component adhesive must be used within the applicaable period after putting in RE.

    The length of applicable period is not only related to the polymer content of adhesive, but also other relevant components(like resin, antioxygen, plasticizer, solvent,etc.

    When close to the applicable period,usually a few hours or one working day, adhesive becomes more difficult to operate, and viscosity rises soon.

    Finally, It becomes the irreversible jelly. 100 quality adhesive, Hydroxyl polyurethane (Polyurethane account for around 20%), RE dose 4-7. Chloroprene rubber (Rubber account for around 20%), RE does 4-7.

    Storage

    Please stored in the original sealed jar under 23℃, the products can be preserved stable for 12 months.

    It very sensitive to the mosture; it will be produce carbon dioxide and insoluble urea in the reaction with water.

    If exposure to teh air or light, it will speed up color changes, but the practical function will not be affected.

    Package

    750 g/bottle or 50 kg/drum or 180 kg/drum or based on customer's requirements.
