Features:
● Main components: modified epoxy resin, nanomaterials, other additives
● Component A: Component B = 2:1, two-component anchoring adhesive, fast-cure, epoxy-based anchoring adhesive, nearly odorless, non-toxic, permenent thixotropy.
● Quick load-bearing after cure, high initial bonding strength, good toughness and anti-pulling capacity
● Low density, excellent thixotropy, smooth, no sediment
● Good resistance to high temperature, age, chemical corrosion, welding, seismic, flame, etc.
● Almost no shrinkage during curing process
● When properly mixed, adhesive will reveal an even color
● Mixed adhesive should be used up within 10~30 minutes (depending on specific ambient temperature)
● The density is about 1.65~1.70 g/cm3 (cured ), gel time is about 1.5~6 hours
● Barrel package is suitable for applicator gun to inject adhesive
● Suitable for anchor and rebar embedding in all construction base materials, such as cracked and uncracked concrete, granite, etc.
● Suitable for horizontal, vertical and overhead applications
● Suitable for static and seismic loading conditions and heavy-load fixings and fastenings
● Fixing of post-installed rebars and anchors, etc.
● Wide working temperature range: -5℃~ 40℃, available to all working conditions, including dry , water-saturated and water-filled holes, and underwater NJMKT underwater MT-500), long-term stable loading performance
● NJMKT Epoxy Anchoring Adhesives specialized for low temperature, which has good performance in the temperature of -5℃
Operating environment:
Dry condition
Wet condition
Underwater condition
Package:
Packing: 10kg barrel
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
Handle with care, protect from rain, sunlight and place upward during loading and unloading transportation
If the temperature is low, component A and B can be separately warmed in 40 ℃ warm pot (barrel) to decrease the viscosity
The construction environment temperature is better for below 40 ℃, at normal temperature gel time is 2 hours, initial cure time is 24 hours, at negative temperature or wet condition, cure time will be a little longer.
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
Standard: GB50367-2013, GB50728-2011
NJMKT Epoxy Anchoring Adhesives 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".
