Rust’s Worst Enemy

Bridges and ships battle saltwater corrosion. Silane coupling agents use dual-bonding technology to make coatings "grow" onto metal surfaces.

Simplified Science

1. Chemical Bonding: Hydrolyzed silanes develop "micro-tentacles"—one end grips metal oxides, the other bonds with paint resins.

2. Active Protection: New dual-amine silanes absorb moisture to form protective silica layers.

The Hong Kong-Zhuhai-Macao Bridge’s steel pilings use silane-enhanced epoxy coatings, lasting 120 years—3x longer than conventional paints!
