Reservoir abrasion-resistant and corrosion-resistant epoxy mastic, Chengkan Institute hydraulic elastic epoxy mastic

Main Applications

The application scope of flexible epoxy mortar is very extensive, mainly including: • Anti-seepage treatment of concrete cracks and deformation joints: It can be used for surface sealing and crack grouting, serving to prevent seepage and water leakage. • Water conservancy, hydropower, tunnel, and subway engineering: Commonly used for impact and abrasion resistance, as well as cavitation protection in water diversion tunnels and water conveyance galleries of hydropower stations, as well as for joint sealing and leakage control in subway shield tunnel segments. • 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 environments such as chemical plants, petroleum facilities, and docks against acid, alkali, and salt corrosion, as well as for anti-corrosion in sewage treatment tanks and acid-alkali resistant floors. 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. • Excellent elasticity and flexibility: The elongation rate can reach over 80%, and some proprietary formulations can even exceed 200%. This allows it to effectively adapt to the opening and closing of joints and structural displacements, avoiding cracking due to vibration or deformation. • Outstanding durability: It possesses excellent aging resistance, fatigue stress resistance (capable of withstanding millions of cycles of fatigue loading), resistance to acid, alkali, and salt corrosion, impermeability, and freeze-thaw resistance. • Environmental friendliness and construction convenience: Typically solvent-free, environmentally friendly, and non-toxic. Some products have the ability to cure and bond even on wet substrates or in the presence of standing water. Its coating has a long open time, facilitating large-area construction; thick-layer application does not sag, making it suitable for vertical surface treatment.
