Advantage
Synergistic effect of chemical bonding force and mechanical biting force
The modified epoxy material adheres tightly to the concrete substrate through intermolecular forces. At the same time, it penetrates into the micropores of the substrate to form a "mechanical locking key", enabling the steel bar and the concrete to form an integral stress system. The anchoring strength approaches or reaches the effect of pre - embedded steel bars.
High chemical stability
Epoxy resin itself has good resistance to acid, alkali, and salt - fog corrosion. After modification, its resistance to medium erosion is further enhanced, making it suitable for harsh environments such as humidity and chemical pollution (e.g., underground projects and marine projects).
Advantages in weather resistance and anti - aging
By adding anti - aging additives, it can resist the influence of factors such as ultraviolet rays and temperature changes (-40°C to +80°C). Its performance remains stable during long - term use, and its service life can reach more than 50 years, far exceeding that of ordinary rebar - planting adhesives.
