The rebar adhesive is a high-performance two-component epoxy-based adhesive specifically designed for anchoring steel bars, threaded rods and steel plates into concrete, masonry and other substrates, widely used in building reinforcement, structural renovation, bridge maintenance, tunnel construction and precast component installation. It offers outstanding advantages including strong bonding strength that exceeds the tensile strength of concrete, ensuring firm and reliable anchoring; excellent corrosion resistance that protects embedded steel from rust and deterioration, extending the service life of structures; good workability with easy mixing and smooth application, adapting to various construction environments and different rebar sizes; and stable performance under harsh conditions such as high temperature, humidity and vibration, complying with relevant construction standards and being suitable for both professional large-scale projects and small-scale reinforcement operations.
Features
High Bonding Strength: Epoxy-based formula provides superior adhesion between rebar and concrete, with bonding strength higher than concrete tensile strength, ensuring stable and reliable anchoring effect.
Two-Component Design: Easy to mix in a fixed ratio, fast curing (adjustable curing time according to temperature), and forms a hard, non-shrinkable bond after curing.
Excellent Corrosion Resistance: Effectively isolates steel bars from moisture, chemicals and other corrosive substances, preventing rust and prolonging the service life of reinforced structures.
Wide Applicability: Suitable for anchoring various steel bars, threaded rods and steel plates into concrete, masonry, stone and other substrates, adapting to different construction scenarios.
Good Workability: Low viscosity, easy to pour and inject into drill holes, ensuring full contact between adhesive and rebar/substrate, no sagging during vertical application.
Durable and Stable: Resistant to high temperature, humidity, vibration and aging, maintaining stable performance for a long time, complying with national and industry construction standards.
Applications
Building Reinforcement and Renovation: Anchoring steel bars in concrete beams, columns, slabs and walls for structural reinforcement; adding new load-bearing components, such as balconies, canopies and staircases, to existing buildings.
Infrastructure Projects: Bridge, tunnel and viaduct reinforcement; anchoring steel bars in highway guardrails, railway sleepers and municipal engineering structures to enhance structural stability.
Industrial and Commercial Construction: Anchoring steel frames, brackets and equipment bases in factories, workshops, shopping malls and office buildings; fixing curtain wall supports and decorative steel components.
Residential Construction: Home renovation projects, such as installing railings, awnings and air conditioning brackets; reinforcing load-bearing parts of old houses to improve safety performance.
Special Engineering: Seismic reinforcement of buildings in earthquake-prone areas; anchoring steel bars in precast concrete components, prefabricated houses and temporary structures.
