Description
The Chem-Set™ H2O Glue AquaBonder Underwater Adhesive is a toughened, two-part structural adhesive designed to bond a wide range of plastics, fiberglass, and PVC. Engineered for pool, spa, and marine repairs, AquaBonder cures reliably at room temperature—even in submerged and damp conditions—making it a go-to solution for pipes, skimmers, main drains, and plastic components.
Its fast fixture time, high lap shear strength, and minimal surface prep requirements make it both installer-friendly and performance-driven. Unlike H2O Epoxy (optimized for concrete and stone), AquaBonder excels with non-porous materials such as ABS, engineered plastics, and composites.
Key Features & Benefits
-
Bonds Difficult Plastics: Works on PVC, ABS, fiberglass, epoxy, urethane, and more.
-
Minimal Prep Needed: Bonds even on poorly prepared surfaces.
-
Fast-Setting: Fixture time of 10–15 minutes at 72°F.
-
Room-Temperature Cure: No heat required.
-
Non-Sagging Formula: Holds in place for vertical or overhead applications.
-
Durable Bonds: Resistant to weathering, impact, and solvent exposure.
-
High Strength: Lap shear values up to 3,500 psi on GBS (glass bead-filled substrate).
Common Applications
-
Repairing pool and spa pipes, skimmers, and drains
-
Bonding fiberglass panels and PVC components
-
Structural repairs on ABS and other engineered plastics
-
Fixing marine plastic parts exposed to water and weather
-
General-purpose underwater bonding where fast fixture is required
