As record-breaking rainfall batters China during the 2024 flood season, demand for building waterproofing has surged. A breakthrough polysilazane nano-coating developed by a CAS (Chinese Academy of Sciences) team is now being applied to landmark projects in Shenzhen. Its molecular structure penetrates micro-pores in building materials, forming an ultra-dense film with over 3 times the weather resistance of traditional materials. This liquid-applied coating cures to a ceramic-like hardness, withstanding impacts equivalent to Category 14 typhoon-driven rain. Crucially, it contains no volatile solvents, aligning with new green building regulations. Experts predict such silicone technologies will redefine architectural waterproofing standards nationwide.
