Underwater Damp Environment Special Construction Structural Adhesive Underwater Construction Structural Adhesive Solution

The selection of raw epoxy resin differs; it is used in conditions with relative humidity above 90%, ensuring effective bonding between the original component and the substrate, as well as guaranteed curing time. Under special high-humidity conditions, underwater damp structural adhesives can easily handle the situation.
Structural adhesives that can be applied normally in underwater and damp conditions fully ensure construction quality and progress. Damp structural adhesives include impregnating adhesive, steel bonding adhesive, grouting adhesive, rebar planting adhesive, crack pouring adhesive, and crack sealing adhesive.

I. Product Features

Resistant to damp-heat aging, freeze-thaw cycles, and medium erosion with excellent performance.

Good workability, no delamination, no segregation, excellent thixotropy, saving usage amount.

Maintains ultra-high bonding strength and impact resistance even in underwater and damp environments.

II. Application Scope

Repair and bonding of roads, bridges, tunnels, and pipelines with relative humidity above 90%.

Anchoring of various load-bearing and non-load-bearing bolts to concrete and masonry with relative humidity above 90%.

Bonding and defect repair of concrete components, masonry components, wooden components, and metal components with relative humidity above 90%.

Reinforcement and renovation projects such as bonding steel plates, carbon fiber cloth, or rebar planting to concrete and masonry components with relative humidity above 90%.

III. Performance Indicators

Note: The specialized building structural adhesive for underwater and damp environments complies with the standard: GB50728-2011 "Technical Code for Safety Appraisal of Engineering Structure Reinforcement Materials".

IV. Precautions

When bonding steel in water-containing environments on the ground, the water must be drained first, and then the process for bonding steel plates under ordinary conditions should be followed. The same applies to repairs.

When bonding steel in completely underwater environments, first use an underwater grinder to remove attachments from the concrete surface. Then, mix the adhesive in the correct proportion on the ground, stir evenly, and have a diver apply it directly to the concrete surface or steel plate underwater. The same applies to underwater concrete repair.
