Steel Bonding Adhesive (Liquid)
Structural Adhesives
Strong construction adhesives for bonding steel parts to concrete structures for structural strengthening
The steel bonding adhesive (liquid) is a groutable structural epoxy, developed for precision filling and high-strength bonding in steel-to-concrete reinforcement applications. Certified through structural safety evaluations, this metal bonding adhesive delivers outstanding impact resistance and fatigue durability, making it suitable for use in dynamic load environments such as railway and highway bridge repairs.
Formulated to meet diverse jobsite demands, the liquid steel bonding adhesive supports curing in standard, humid, and low-temperature conditions, providing flexibility for installation across varying climates and working environments.
