Steel Bonding Adhesive (Paste)

Strong construction adhesives for bonding steel parts to concrete structures for structural strengthening

The steel bonding adhesive (paste)is a high-performance and labor-efficient epoxy material, engineered for structural strengthening and retrofitting. It is widely used for bonding steel plates to concrete, reinforcing load-bearing members, and securing equipment to structural surfaces, while ensuring high performance and structural reliability in critical construction environments.

Ideal for dry application scenarios, the adhesive offers high bond strength, easy handling, and excellent compatibility with concrete and steel substrates, making it suitable for both repair and reinforcement in civil, industrial, and infrastructure projects.

Features
  • Lightweight formula with a density of only 1.6 g/cm³—approximately 30% lighter per volume than typical market alternatives, reducing material weight without compromising strength
  • Persistent thixotropy prevents adhesive flow, minimizing the risk of hollow spots and rework caused by sagging or displacement
  • Maintains excellent vertical and overhead workability, with no sagging during application
  • Offers strong resistance to moisture, heat aging, chemical corrosion, and water exposure; can be applied in low temperatures and, in special variants, even in wet conditions
  • Available in standard, low-temperature, and damp-environment curing formulations, adaptable to varied on-site conditions
  • Provides high bonding strength, exceptional toughness, and peel resistance; flexural strength reaches up to 90.6 MPa
  • Reinforced with eco-friendly nano-fillers, delivering compressive strength up to 56.2 MPa
