High-performance two-component epoxy adhesive providing rigid bonds for load transfer in wind turbine precast segments and structural applications.
Product Introduction
Our Structural Epoxy Adhesive for Wind Turbine Precast Segments is an advanced two-component epoxy adhesive designed for high-strength bonding of precast concrete segments in wind power hybrid towers, bridges, tunnels, and structural repairs. Element bonding adhesives like this provide a rigid bond between elements to transfer loads effectively, ensuring reliable adhesion approved by CNAS-certified laboratories. This concrete bonding adhesive excels in epoxy for concrete repair, offering superior mechanical strength and durability. Ideal as a wind tower epoxy adhesive for onshore wind turbine assembly, it outperforms in thixotropic epoxy adhesive properties for non-sag performance.
Product Characteristics
◆ Good marina resistance, stronger bonding force in dry condition.
◆ High strength, high elastic modulus, low creep, waterproof and anti-corrosion.
◆ Good operability, special conditions can meet the wet surface and low temperature construction.
◆ High thixotropic paste, self-lubricating effect, easy to mix and apply, no hanging, no dripping.
◆ Easy to compact, no water seepage in adhesive joints, strong bonding ability with concrete, no rusting of steel reinforcement, and can effectively transfer loads.
