    Features:

    ● Component A: Component B = 2:1, two-component carbon fiber adhesive, modified epoxy adhesive

    ● Nearly odorless, non-toxic, there is almost no shrinkage during curing process

    ● Good resistance to weather, high temperature, age, corrosion, etc., excellent mechanical performance and high durability 

    ● strong permeability, high tensile strength and bonding strength. 

    ● Fast and easy stirring ensures accurate mixing proportion 2:1, when properly mixed, adhesive will be an even color for use

    ● NJMKT carbon fiber adhesive specialized for low temperature can still keep a perfect permeability in the temperature of -5℃, you can choose our special low temperature adhesive depending on your installation ● Mixed adhesive should be used up within 20~60 minutes (depending on specific ambient temperature)

    ● The density is about 1.15~1.20 g/cm3 (cured ), gel time is about 3~8 hours

    ● Moderate viscosity, meet the requirement of bonding thickness (1.5±0.5) mm for carbon fiber composite materials in "Code for Acceptance of Construction Quality of Strengthening Building Structures"


    ● Adhesion of various fibers, such as carbon fiber, basalt fiber, glass fiber, aramid fiber (kevlar fiber), etc.

    ● Widely used for carbon fiber materials, high initial adhesion and sustained tensile strength, especially strong permeability for carbon fiber sheet

    ● Wide working temperature range: 5℃~ 40℃, available in all working conditions, including dry, wet and underwater environment

    ● Excellent thixotropy and nearly non-drip for horizontal, vertical and overhead applications, low flowability for vertical construction



    Operating environment:

    *Dry condition

    *Wet condition

    *Underwater condition


    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


    Packing: 

    ● Two kinds of package, 30kg (A+B two barrels)/pair; 15kg (A+B two barrels)/pair


    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


    Standard: GB50367-2013, GB50728-2011

    NJMKT promises to meet the technical requirements of the following GB50367-2013 "Design code for concrete structure reinforcement" and GB50728-2011 "Technical code for safety identification of reinforcement materials for engineering structures".
