Spillway abrasion-resistant epoxy mortar, elastic epoxy mortar for hydropower stations

Flexible epoxy mortar is a two-component elastic sealing material modified with epoxy resin. It combines the high strength and strong bonding force of epoxy resin with the excellent elasticity of flexible materials, making it particularly suitable for sealing and protecting concrete structures that need to withstand dynamic loads or deformation.Main Characteristics

The performance advantages of flexible epoxy mortar make it an ideal choice in many demanding environments: • High bonding strength: It forms strong bonds with both concrete substrates and rubber surfaces, with dry bonding strength exceeding 2.0 MPa and wet bonding strength exceeding 1.5 MPa. • Outstanding elasticity and flexibility: The elongation rate can reach over 80%, and some proprietary formulations even exceed 200%. This allows it to effectively adapt to joint movements and structural displacements, preventing cracking due to vibration or deformation. • Excellent durability: It possesses superior aging resistance, fatigue stress resistance (capable of withstanding millions of cycles of fatigue loading), resistance to acid, alkali, and salt corrosion, as well as impermeability and freeze-thaw resistance. • Environmental friendliness and ease of construction: Typically solvent-free, environmentally friendly, and non-toxic. Some products can be applied underwater, curing and bonding even on damp substrates or in the presence of water. Its long open time facilitates large-area application, and it can be applied in thick layers without sagging, making it suitable for vertical surfaces.Main Applications

The application range of flexible epoxy mortar is extensive, primarily including: • Anti-seepage treatment for concrete cracks and deformation joints: Used for surface sealing and crack grouting to prevent water penetration and leakage. • Hydraulic, hydropower, tunnel, and subway projects: Commonly employed for erosion and cavitation protection in water diversion tunnels and conveyance conduits of hydropower stations, as well as for joint sealing and leakage control in subway shield segment joints. • Reinforcement and repair of concrete structures: Used to repair cracks, honeycombs, voids, and other defects in building beams, columns, pile caps, etc. • Anti-corrosion protection: Suitable for protecting and repairing concrete or metal components in chemical, petroleum, dock, and other environments against acid, alkali, and salt corrosion, as well as for anti-corrosion applications in sewage treatment tanks and acid-resistant floors.
