    Main Components: Modified epoxy resin, nanomaterials, other additives

    Component A: Component B = 2:1


    Features:

    Two-component anchoring adhesive, fast-cure, epoxy-based anchoring adhesive, nearly odorless, non-toxic, no drip, no sag, and easy clean up

    Quick load-bearing after cure, high initial bonding strength and anti-pulling capacity

    Strong anchorage bonding strength achieves the effect of embedded parts

    Higher strength than the concrete around it after cure

    Compared with other mechanical or chemical anchor, it has a larger load-bearing capacity

    There is almost no shrinkage during curing process

    No expansion stress, provide the best spacing and edge distance

    Good resistance to weather, high temperature, age, chemical corrosion, welding, seismic, flame, etc.

    Fast and easy dispensing by special double spiral mixing nozzle to ensure accurate mixing proportion

    When properly mixed, adhesive will be an even color to injection for use

    ● Suitable for anchor and rebar embedding in all construction base materials, such as cracked and uncracked concrete, granite, etc. 

    ● It almost can be applied to any holes with different diameter and depth

    ● Wide working temperature range: -5℃~ 40℃, available in all environmental/weather working conditions, including dry concrete, water-saturated and water-filled holes, and underwater environment (choose NJMKT special underwater adhesive), long-term stable loading performance

    ● NJMKT adhesive specialized for low temperature can still keep a perfect performance in the temperature of -5℃, you can choose our special low temperature adhesive depending on your installation condition

    ● Suitable for horizontal, vertical and overhead applications

    ● Suitable for static and seismic loading conditions and heavy-load fixings and fastenings 

    ● Widely used for curtain wall, guard rail, sound barrier, bridge beam, equipment fixing, seismic strengthening, repairing and retrofitting and bracing of reinforced concrete buildings, rebar doweling, connection of post-installed rebars and anchors, etc.

    Operating environment:

    ● Dry condition

    ● Wet condition

    ● Underwater condition


    Installation

    NJMKT NJMKT-390 Anchorage Adhesive

    1. Drill the hole to proper depth and diameter per specifications using drill systems.

    2. Clean the hole using brush and compressed air for three times.

    3. Use specialized cartridge or nozzle, discard the first injections until an even color is achieved. Inject adhesive until up to 2/3 depth of drilled hole.

    4. Insert the rebar/anchor/bolt/rod slowly into the bottom of the hole clockwise.

    5. Do not knock or strike the steel element during cure time. Adhesive must be fully cured before applying any load or torque.

    6. Finish installation and continue the follow-up construction and apply the load.


    Packing

    Packing: 390ml cartridge (24 pieces/carton)


    Storage:

    Shelf life: At least 12 months from date of manufacture in unopened container when store in dry and well-ventilated place. Please store in ambient temperature from 5 ℃ to 40 ℃, away from open flame, heating devices

    Adhesive specialized for low temperature can be stored in ambient temperature from -5 ℃ to 40 ℃

    Handle with care, protect from rain, sunlight and place upward during loading and unloading transportation


    Caution

    Mix the adhesive well according to its weight proportion strictly

    Construction crew should take steps of protective measures to keep it from eyes

    Remaining adhesive cannot be poured into original barrels

    Cartridge cap design is available for several times to use the total amount of adhesive, avoid wasting
