Injection Adhesive for Steel Bonding
ASR-200 Injection Adhesive is a solvent-free, two-component, low-viscosity modified epoxy resin adhesive. It is widely used for structural strengthening realized by steel-to-concrete bonding. ASR-200 can also repair cracks in concrete, grout base plates, ground bolts and holes.
ASR-200 infiltrates well into concrete and has great strength performances. It is highly durable and resistant to environmental effects, stress, acid and alkali.
Uses
Reinforcement of large-area steel blocks or injection bonded steel whose thickness is ≥5mm outside the concrete components, such as bridges
Reinforcement of wet-encased steel concrete structure
Grouting and repair of concrete internal defects (honeycombs, holes)
Perfuse, glue and construct the prefabricated component assembly gaps, steel-concrete assembly gaps, and wide concrete cracks (1-5mm)
Secondary grouting and cable hole grouting of anchor bolts and equipment bottom plate
Advantages
Two components and solvent-free
High permeability into concrete surfaces
High resistance to hygrothermal aging, heat aging, freezing-thawing, long-term stress, and fatigue stress
Good resistance to environmental effects such as acid, alkali, salt spray, and seawater immersion
Easy to apply
Applicable within a wide temperature range
