Steel and concrete structures in coastal or de-icing environments face severe corrosion. Traditional methods like zinc coatings are costly and short-lived. Silane-based hybrid coatings offer a sustainable alternative.

Silanes (e.g., methyltriethoxysilane) penetrate porous concrete or rusted steel, reacting with surface hydroxyl groups to form a protective siloxane network. This barrier resists water, salt, and UV degradation. Field studies show silane-treated concrete bridges exhibit 70% less chloride ingress after a decade.

Moreover, silane primers enhance the adhesion of topcoat systems, ensuring long-term protection for skyscrapers, pipelines, and marine infrastructure. Their low VOC content aligns with green construction trends.
