    Silicone sealant for IOTA7500A lamps


    Description:

    The silicone sealant for IOTA7500A lamps is a one-component, medium-high modulus, neutral-cured silicone elastomer seal designed for the bonding and sealing of lamp housings and bulbs on bulbs in energy-saving lamps and LED lamps. gum. It has fast curing speed, good adhesion, high tensile strength, excellent electrical insulation, high and low temperature resistance, aging resistance and UV resistance. Also suitable for general sealing and electrical insulation.


    Features:

    1. Very low volatility, making the lamp difficult to fog.

    2. Neutral curing, non-corrosive to most materials.

    3. No primer is required for a variety of substrates.

    4. Excellent heat resistance and cold resistance; continuous operation from -55 ° C to 200 ° C.

    5. Excellent weatherability, ozone resistance and chemical resistance.

    6. Excellent electrical insulation.

    7. Single component, easy to operate.

    Use:

    1. Used for bonding, sealing and reinforcement of bulb lamps.

    2. Used for general lighting industrial sealing and bonding.

    3. Used in a variety of different OEM and assembly lines.

    Color and packaging:

    The color is white and is packed in 300ML plastic hose or 100ML aluminum tube.

    Storage and expiration date:

    Non-dangerous goods, please store in a cool dry place below 27 °C, valid for 12 months.


    Construction method:

    1. Identify the substrate First, eliminate the factors that cannot be determined.

    Such as: some metal coatings and lacquer layers.

    2. Clean the substrate Remove the loose layer that needs to be applied.

    If there is a coating or lacquer, make sure there is sufficient adhesion. Use a special cleaning agent to clean the area to be glued, making it clean, hard, dry, free of grease and surface dirt such as mold release agent, curing film and hydrophobic agent.
