Structural Adhesives
Structural adhesive for fast setting anchoring of threaded and reinforcing bars in concrete
Developed for time-critical applications, the fast-curing anchoring adhesive is formulated to accelerate installation schedules without compromising performance. Ideal for sectors such as rail maintenance and emergency infrastructure repair, this structural adhesive reaches load-bearing strength in just 2 hours at 25-30°C, significantly improving onsite efficiency.
The formulation retains all the standard features such as high bond strength, seismic resistance, durability under fatigue loading, and long-term chemical stability while providing faster turnaround for projects that demand tight construction timelines.
