Product overview
Performance and application overview.
Zrete underwater adhesive excels in tough wet conditions. This underwater structural epoxy adhesive uses special epoxy resin to bond effectively when humidity exceeds 90%. It cures on time without issues, making it perfect as a wet surface epoxy for reinforcement and repairs
Why Choose Zrete Underwater Adhesive
Excels in Wet Conditions: This underwater structural epoxy adhesive uses special epoxy resin to bond effectively in humidity over 90%. It cures reliably as a wet surface epoxy, ideal for tough reinforcement and repairs.
Versatile Applications: Perfect for pasting steel plates, carbon fiber cloth, or planting rebar in concrete and masonry. It serves as an underwater repair adhesive for anchoring bolts or fixing defects in wood and metal. Great for humidity resistant adhesive needs in roads, bridges, tunnels, and pipelines.
Efficient and Durable: No segregation or layering, with good operability as a marine structural bonding solution. Reduces glue waste through thixotropy while maintaining impact resistance and fighting damp-heat aging in submerged areas.

Product usage
Application and installation guidance.
Prepare surfaces for best results with Zrete underwater adhesive. For above-ground wet spots, drain water first. Then apply as a wet surface epoxy following dry bonding steps.
In full underwater areas, grind off debris like shellfish using an underwater tool. Mix the underwater structural epoxy adhesive on land by ratio. A diver coats it directly on concrete or steel for underwater repair adhesive tasks.
This humidity resistant adhesive suits marine structural bonding. Use it to anchor bolts, seal joints, or repair defects in wet concrete adhesive projects. Always store in cool, dry places for optimal performance.
1.Structural bonding in underwater or humid environments
2.Repair and strengthening of bridge piers, tunnels, dams, tanks, harbors
3.Anchoring of bolts, dowels, or rebar in moist or flooded job sites
4.Bonding of steel plates, CFRP fabric, or masonry units in high-humidity conditions
5.Concrete crack injection and defect repair underwater
