H2O Glue® Aqua-Bonder Underwater Adhesive

Product Description

H2O Glue® Aqua-Bonder Underwater Adhesive is a toughened structural adhesive designed for strong, load-bearing bonds on engineered plastics and other demanding substrates. It can be used wet or dry, making it a practical solution for underwater, outdoor, and high-moisture bonding applications.

This 50ml cartridge features a 1:1 mix ratio, room-temperature cure, non-sagging consistency, and rapid fixture time. The adhesive bonds to materials including PVC, fiberglass, ABS, FRT, PBT, PPO, polycarbonate, epoxy, RIM urethane, wood, and poorly prepared surfaces where outdoor weathering or solvent exposure may be expected.

Ideal for professional, industrial, marine, pool, spa, and repair applications, H2O Glue provides strong gap-filling performance and cures to a white finish.

Specifications

Applications

Great for bonding and repair work involving:

• Pools and spas

• Marine repairs

• Wet or submerged surfaces

• PVC and fiberglass components

• Plastic housings and assemblies

Application Instructions

1. Attach the cartridge to a compatible 50ml dispensing system.

2. Open the tip and “burp” the cartridge until both sides dispense evenly.

3. Attach the mixing nozzle.

4. Apply the mixed adhesive directly to one surface as an even film or bead.

5. Assemble parts within the recommended working time.

6. Apply firm pressure to minimize gaps and ensure contact.

7. For best adhesion, use a bond line thickness of approximately 0.015"–0.030".

Storage

Store between 55°F and 75°F. Continuous storage above 75°F may reduce shelf life. Prolonged exposure above 100°F should be avoided. Shelf life may be extended by refrigeration between 45°F and 55°F. Do not freeze.
